Natural History of the Mammalia of India and Ceylon - Robert Armitage Sterndale 7 стр.


SIZE.Head and body, about 3 inches. This bat is alluded to by Jerdon as M. Horsfieldii.

RHINOLOPHINÆ

Nasal leaf complicated, and crests resting on the forehead, presenting more or less the figure of a horse-shoe; tail long and placed in the interfemoral membrane; ears large, but separate, and not joined at the base, as in the last genus; without a tragus, but often with a lobe at the base of the outer margin; wings large and long; forefinger of a single joint.

GENUS RHINOLOPHUS

Nose-leaf cordate, or semi-orbicular, bi-lobed in front of the nostrils; a longitudinal crest along the nose and an erect frontal leaf posteriorly more or less lanceolate.Jerdon.

Dental formula: Inc., 2/4; can., 11/11; premolars, 22/22; molars, 33/33.

NO. 39. RHINOLOPHUS PERNIGERvelLUCTUSThe Large Leaf-Bat (Jerdon's No. 17)

HABITAT.Nepaul, Darjeeling, Khasya Hills.



DESCRIPTION.Ears very large, much longer than the head; broad, acutely pointed; nasal apparatus very complicated; the lower leaf very large, concealing the upper lip like a door knocker; the upper leaf like a graduated spire; ears transversely striate; a rather large semi-circular lobe at base of ear; fur long, dense, soft, and lax, slightly curled or woolly black with a silvery grizzle, or greyish-black or rich chestnut-brown.Jerdon.

SIZE.Length, 3¾; tail, 1¾; wing expanse, 17 inches.

NO. 40. RHINOLOPHUS MITRATUSThe Mitred Leaf-Bat (Jerdon's No. 18)

HABITAT.Chybassa, Central India, Mussoorie(?)

DESCRIPTION.Ears large; anti-helix moderately developed; upper leaf triangular acute; tail extending beyond the tibia; color above light brown; paler beneath.Jerdon.

SIZE.Head and body, 2½ inches; tail, 1½ inch; wing expanse, 12 to 14 inches.

NO. 41. RHINOLOPHUS TRAGATUSvelFERRUM-EQUINUMThe Dark-brown Leaf-Bat (Jerdon's No. 19)

HABITAT.Nepaul, Mussoorie.



DESCRIPTION.Upper process like a barbed spear-head; central one small and narrow, a little expanded at the summit; anti-tragus less developed than usual; lips simple; colour a uniform deep brown, with tips of the hair paler, and somewhat rusty.Jerdon.

SIZE.Head and body, 2-5/8 inches; tail, 1-7/8 inch; wing, 15½ inches.

The tail of this species seems unusually long. It is found in cavities of rock, and issues forth soon after dusksooner, according to Hodgson, than the species of vespertilio.

NO. 42. RHINOLOPHUS PEARSONIIPearson's Leaf-Bat (Jerdon's No. 20)

HABITAT.Lower Himalayan range, Darjeeling, Mussoorie, &c.

DESCRIPTION.Colour above dark brown, with a slight shade of chestnut; underneath brown, with a sooty cast; fur very long, dense and soft; ears distinct, with an additional rounded lobe below, measuring anteriorly nearly three-fourths of an inch; point of the facial crest moderately developed; length from the tip of the nose to root of tail three inches; tail half an inch; length of fore-arm two inches; expanse of the wings eleven inches. Although allied to Mr. Hodgson's R. tragatus, possesses distinct characters.Horsfield.

SIZE.As given by Horsfield above.

This bat was first sent from Darjeeling by Mr. J. T. Pearson, and was named after him. It has also, according to Jerdon, been found by Captain Hutton at Mussoorie; it is therefore reasonable to suppose that it inhabits the whole range of the lower Himalayas. One striking difference between it and the last species is the very short tail, and it is easily to be recognised by the great length of the fur.

NO. 43. RHINOLOPHUS AFFINISThe Allied Leaf-Bat (Jerdon's No. 21)

HABITAT.Ceylon, Burmah, and perhaps the Malabar coast.

DESCRIPTION.Above bright red ferruginous brown; tips of hair darker, paler beneath; ears pointed and external; edge deeply emarginated; internal edge and basal third of external surface hairy; anti-helix well developed; nasal process apparently very similar to that of R. mitratus (Kellaart). Upper leaf triangular, emarginate at the tip, reaching above the base of the ears (Jerdon).

SIZE.Head and body about 2-3/10 inches; tail, 1 inch; wing extent, 12 inches.

This bat seems to vary much in colour. Kellaart says some are of a brighter red than others, and a few had a yellower tinge. Another marked variety was of a uniform pale yellow brown.

NO. 44. RHINOLOPHUS ROUXIThe Rufous Leaf-Bat (Jerdon's No. 22)

HABITAT.India generally.

DESCRIPTION.Ears large, pointed, externally notched; tragus broad; tips of upper nose-leaf triangular, with its sides well emarginate, reaching above the base of the ears; no upper incisors [as in Megaderma lyra]; lower molars only five; canines very large; fur short, crisp; colour above smoky brown in some, reddish brown in others, and golden rufous in some; beneath paler.Jerdon.

SIZE.Length, 2-3/8 inches; tail, 1-1/8; wing expanse, 13 inches.

Hodgson considers this bat as allied to the two following species. It is the R. lepidus of Blyth.

NO. 45. RHINOLOPHUS MACROTISThe Large-eared Leaf-Bat (Jerdon's No. 23)

HABITAT.Lower Himalayas.

DESCRIPTION.Ears very large, broad, oval, with pointed recurved tip, and a large obtuse tragus; anterior central crest of nose-leaf produced in front over the top of the flat transverse front edge; hinder leaf lanceolate triangular; above sooty brown or light earthy olive-brown, paler below, some with a rufous or Isabelline tint; no pubic teats.Jerdon.

SIZE.Head and body, 1¾ inch; tail, ¾; wing expanse, 9¾.

NO. 46. RHINOLOPHUS SUB-BADIUSThe Bay Leaf-Bat (Jerdon's No. 24)

HABITAT.Nepaul.

DESCRIPTION.Ears not larger than the head, obtusely pointed and ovoid; nasal appendage quadrate, with a transverse bar nearly surmounting it; upper leaf triangular, with slightly emarginate sides; clear brown above, paler below and on head and face.

SIZE.Head and body, 1½ inch; tail, 1¼; wing expanse, 7½.Jerdon.

NO. 47. RHINOLOPHUS RAMMANIKA (Kellaart)

HABITAT.Ceylon.

DESCRIPTION.Above rufescent, beneath ashy brown; face slightly fulvous; round the base of the ears and on the sides of the posterior half of the body bright fulvous; tail enclosed in the interfemoral membrane.

SIZE.Head and body, 2½ inches; tail, 1; wing expanse, 10 inches.

This is a doubtful species. Dr. Kellaart got one from Amanapoora hill at Kaduganava. He says: "As the specimen reached us in a dried condition, we are unable to say anything more about its nasal processes than that in place of a transverse process above the nostrils it had a small triangular peak over the usual horse-shoe process surrounding the nasal opening. This triangular crest was hairy; superiorly there was no appearance of a sac above it to the best of our recollection."

NO. 48. RHINOLOPHUS ANDAMANENSIS

HABITAT.Southern Andaman Island.

HABITAT.Southern Andaman Island.

DESCRIPTION (apud Dobson).Like R. affinis generally, but the anterior horizontal horse-shoe shaped membrane is very broad, completely concealing the muzzle when viewed from above, as in R. Pearsonii; the posterior terminal leaf is also much longer, produced backwards between the ears, and not concave on the sides as in R. affinis. The thumb is also much longer. Fur bright reddish brown above and beneath.

NO. 49. RHINOLOPHUS MINOR

HABITAT.Burmah, Yunan.

DESCRIPTION.Light brown above, greyish brown beneath; ears slightly shorter than the head, sub-acutely pointed; anti-tragus large, separated by a deep angular notch; lower lip with three vertical grooves.

SIZE.Length of head and body from 1 to 1¾ inch.

NO. 50. RHINOLOPHUS COELOPHYLLUS

HABITAT.Burmah.

DESCRIPTION.Fur brown, with whitish roots, light brownish white below; ears large, with pointed tips projecting outwards; "anti-tragus large, separated by an angular emargination from the outer margin of the ear; horse-shoe large; horizontal margins of central nose-leaf triangular, small; erect portion rather short, with parallel sides and rounded summit, meeting the connected vertical process at the same level" (Dobson). For a more detailed description see Dobson's Monograph, page 53. Three vertical grooves on lower lip.

SIZE.Length of head and body about 2 inches.

NO. 51. RHINOLOPHUS GAROENSIS

HABITAT.Garo Hills, Assam; Himalayas (Mussoorie).

DESCRIPTION (apud Dobson).Ears acutely pointed, with a large anti-tragus, as in R. affinis; anterior vertical process of the sella maintaining the same breadth upwards and rounded off above, considerably exceeded in height by the upper edge of the connecting process, which develops a long acutely pointed projection; terminal portion of the posterior leaf broad with straight sides, forming an almost equilateral triangle.

Wing membrane from the ankles, inter femoral membrane square behind; extreme tip of the tail free.

SIZE.Length of head and body about 1·5 inch.

This bat is figured (head only) in Dobson's Monograph, page 48.

NO. 52. RHINOLOPHUS PETERSII

HABITAT.India. Precise locality unknown.

DESCRIPTION.Ears acutely pointed, with an emargination immediately beneath the tip; anti-tragus large, separated from the outer margin by a deep angular incision; nose-leaf horizontal, horse-shoe-shaped, not so broad as the muzzle; vertical part of the sella almost same breadth upwards, and rounded off above, exceeded considerably in height by the upper margin of the posterior connecting process; lower lip with three vertical grooves; fur dark brown above, greyish brown beneath.

SIZE.Length of head and body, 2·5 inches; tail, 1 inch.

There are two good woodcuts of the head of this bat in Dobson's Monograph.

NO. 53. RHINOLOPHUS TRIFOLIATUS

HABITAT.East coast of India.

DESCRIPTION.Very much like R. perniger (luctus), but is distinguished by its smaller size and by the more pointed vertical process of the central nose-leaf, which in the other is truncated.

SIZE.Length of head and body, 2 inches; tail about 1 inch.

GENUS HIPPOSIDEROS (GRAY) VEL PHYLLORHINA (BONAPARTE)

Nasal-leaf broad, depressed, transverse; ears with transverse wrinkles; a circular sac behind the nasal crest, which can be turned inside out; when alarmed the animal blows it out, and then withdraws it at each breath; it contains a waxy matter of green or yellow colour. Blyth thinks that this sac is affected by the amorous season, as in the case of the infra-orbital cavities of various ruminants and analogous glandular follicles in other animals.

This genus is also distinguishable from the last by the form of the ear conch, the small size of the anti-tragus, and, as Dr. Dobson particularly points out, by the presence of two joints only in all the toes, as also by the number and character of the teeth, which are as follows:

Inc., 2/4; can., 11/11; premolars, 22/22; molars, 33/33.

NO. 54. HIPPOSIDEROS ARMIGERThe Large Horse-shoe Bat (Jerdon's No. 25)

HABITAT.Lower Himalaya ranges; Ceylon.

DESCRIPTION.Nasal-leaf large and square; lips with a triple fold of skin on each side; tragus vaguely developed and wavily emarginate; of a uniform light-brown colour, with maroon tips to the hairs of the upper parts; membranes black.

SIZE.Head and body, 4½ inches; tail, 2½; wing expanse, 22.

Jerdon makes this out to be the same as Kellaart's H. lankadiva and the Malayan H. nobilis, but those are synonymous with Phyllorhina diadema. Kellaart supposed it to be identical with H. insignis, which will be found further on as Phyllorhina larvata, all those bats closely resembling each other in a general way. I think this No. 25 of Jerdon is the same as Peter's Phyllorhina armigera. Hutton found it at Darjeeling, and writes of it as follows:

"When captured alive the large ears are kept in a constant state of rapid tremulous motion, and the animal emits a low purring sound, which becomes a sharp scream when alarmed or irritated. When suspended at rest the tail and inter-femoral membrane are turned up, not in front, like the Rhinolophi, but behind, over the lower part of the back; neither does it appear to envelope itself in its wings so completely as does R. luctus." He then goes on to say he has noticed the tremor of the ears and facial crests in all the Rhinolophi when disturbed, and concludes with a graphic description of this species, sallying forth in the evening to prey upon the noisy Cicadas; leisurely wheeling with noiseless, cautious flight round some wide-spreading oak, "scanning each branch as he slowly passes bynow rising to a higher circle, and then perchance descending to the lower branches, until at length, detecting the unfortunate minstrel, it darts suddenly into the tree, and snatching the still screaming insect from its perch, bears it away."

Jerdon procured specimens at Darjeeling, and Kellaart says it is found in great abundance at Kandy and its neighbourhood; Kurnegalle Tunnel swarms with them.

NO. 55. HIPPOSIDEROS SPEORISThe Indian Horse-shoe Bat (Jerdon's No. 26)

HABITAT.India generally and Ceylon.

DESCRIPTION.Mouse brown or fulvous brown. Occasionally golden fulvous and sometimes dusky black above, paler beneath; membranes dusky brown; interfemoral membrane narrow, enclosing the tail except the last half joint (about 2-10ths of an inch), which is free.

Ear large, erect and pointed, rounded at the base and emarginated on the outer edge; nasal process complicated. "Males have a frontal sac; females none" (Kellaart). Pubis naked, with two inguinal warts.

SIZE.Head and body, 2 inches; tail, 1-2/10; wing expanse, 12.

Inhabits old buildings, wells, &c.

NO. 56. HIPPOSIDEROS MURINUSThe Little Horse-shoe Bat (Jerdon's No. 27)

HABITAT.Southern India, Ceylon, and Burmah.

DESCRIPTION.Muzzle short; body short and thick; a transverse frontal leaf with a sac behind it; no folds of skin on each side of the horse-shoe as in the last species; ears large, naked and rounded; colour dusky brown or mouse, sometimes light fawn; wing membrane blackish; interfemoral membrane large, and including the tail all but the tip.
