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 a.n.a.logous 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., 1--1/1--1; premolars, 2--2/2--2; molars, 3--3/3--3.
NO. 54. HIPPOSIDEROS ARMIGER.
_The 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, 4-1/2 inches; tail, 2-1/2; wing expanse, 22.
Jerdon makes this out to be the same as Kellaart's _H. lankadiva_ and the Malayan _H. n.o.bilis_, 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 pa.s.ses by--now 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 s.n.a.t.c.hing 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 SPEORIS.
_The 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 MURINUS.
_The 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.
SIZE.--Head and body, 1-4/5 inch; tail, 1-1/5 inch; wing expanse, 10.
Jerdon says the mouse-coloured variety is common in the Carnatic, but he has only seen the light fulvous race on the Nilgheries; but Mr. Elliot procured both in the southern Mahratta country. A dark variety of this bat was called _Rhinolophus ater_ by Templeton, and _H. atratus_ by Kellaart; in other respects it is identical, only a little smaller.
NO. 57. HIPPOSIDEROS CINERACEUS.
_The Ashy Horse-shoe Bat_ (_Jerdon's No. 28_).
HABITAT.--Punjab Salt range.
DESCRIPTION.--Similar to the last, but larger, and I should think the argument against _H. atratus_ would apply to this as a distinct species.
NO. 58. HIPPOSIDEROS LARVATUS.
_Syn_.--PHYLLORHINA LARVATA.
HABITAT.--Arracan.
DESCRIPTION.--The fur of the upper part bright fulvous; more or less tinged with maroon on the back, lighter underneath; membranes dusky, but tinged with the prevailing colour of the fur; ears angulated; a minute false molar in front of the carna.s.sial in the upper jaw.
SIZE.--Head and body, 2-3/4 inches; tail, 1-1/4; wing extent, 12.
Kellaart writes of this bat under his _H. aureus_. He describes it as head, neck, and body of a bright golden yellow, with a slight maroon shade on the tips of the hairs on the back. Females paler coloured. Frontal sac only in males; the waxy matter of a yellow colour, and quite transparent.
NO. 59. HIPPOSIDEROS VULGARIS.
_Syn_.--PHYLLORHINA LARVATA.
_The Common Malayan Horse-shoe Bat_.
HABITAT.--Arracan and Malayana.
