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., 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, 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:—
