470 Mr. E. BlytVs Notices of various Mammalia, 



Temminck notices it under tlie name of a siphon, or purse, in 

 Rh. insignis and Rh. speoris" (apud Geoffroy)*. The entire 

 facial crest has been well compared by Mr. Hodgson to " a coat 

 of arms with double field" ; the superior and inferior fields 

 separated by a trilobate fleshy ridge, below which are situate the 

 nostrils in a deep cavity, surrounded by the membrane which 

 forms the lower field, both within and exterior to which are, in 

 some species, additional laminae of membrane. The ears in this 

 group are, in general, less apiculated, and sometimes rounded, 

 and the conch is not continued round to form an anti-helix. 



Some have a more complex membrane surrounding the nos- 

 trils, and three small lateral fringes of membrane exterior to the 

 nose-leaf. 



1. H. armiger (Hodgson), Journ. A. S. iv. 699. — Very closely 

 allied to, if not identical with, H. nohilis (Horsfield) . I cannot 

 however perceive that " the hairs of the axilla, hypochondria, and 

 scapular marks are nearly white," as stated of the Javanese 

 species. Colour uniform light brown, with dark maroon tips 

 to the fur of the upper parts. Length of fore-arm (of a large 

 specimen) three inches and five-eighths, and of tibia an inch and 

 a half. Inhabits the central region of Nepal. 



2. H. larvatus (? Horsfield). — A species which I have little 

 hesitation in identifying with this, has the fur of a brighter fer- 

 ruginous than is represented in Dr. Horsfield^s two figures, and 

 the under-parts more particularly are much deeper-coloured than 

 would appear from the second figure of the plate adverted to. 

 The fur of the upper-parts is vivid fulvous, more or less tinged 

 with maroon upon the back, and weaker towards the base of the 

 hairs ; that of the under-parts being somewhat less intense : 

 membranes dusky, but it would seem tinged with the prevalent 

 hue of the fur. Length about four inches, of which the tail 

 measures one and a quarter; fore-arm two inches and a half; 

 longest finger three and a quarter; tibia an inch and one-six- 

 teenth ; foot with claws five-eighths of an inch : ears angulated, 

 measuring anteally seven-eighths of an inch to tip, and three- 

 quarters of an inch broad; length of head an inch. Both in this 

 species and the last there is a minute false molar anterior to the 

 carnassier in the upper jaw, which appears to be wanting in those 

 which follow. Inhabits Arracan, whence forwarded to the So- 

 ciety's museum by Capt. Phayre, to whom we are likewise in- 

 debted for the next species. 



3. H. vulgaris (? Horsfield) ; a species mentioned by Mr. 



* It is probable that the development of this sinus, and also of the throat- 

 sac of the Taphozoi, depends much on season, like the infra-orbital cavities 

 of various Ruminants and analogous glandulous follicles in many other 

 animals.
