GENUS HIPPOSIDEROS (GRAY) veEL 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 fwo joints only in all the toes, as 
also by the number and character of the teeth, which are as follows :— 
1—1!; pre-molars, 2-2 ; molars, 3—3.
