DESCRIPTIONS OF NEW SPECIES OF MAMMALS. 799 



amoke gray basally in strong contrast. On under parts the fur is broccoli brown 

 throughout, the hairs slightly darker at tip. In the light phase the whole 

 body is mars brown, the hairs everywhere light gray at base, but this feature 

 most noticeable on back. Ears and membranes blackish. This description is 

 based on specimens that have been immersed in alcohol for about six months. 

 Skull and Teeth. — The skuU is so much smaller than that of Hipposideros 

 fulvus that it needs no special comparison. From the skull of H. hicolor it 

 differs in slightly larger size and in several details of structure. The width of 

 the constricted portion of the palate is considerably greater th?n in the allied 

 species, and the interpterygoid space is wider in proportion to its length. 

 Antorbital region more inflated than in either of the allied species. 



The teeth show no peculiarities of form. They are intermediate in size 

 between those of Hipposideros hicolor and H. fulvus. 



Measurements. — For external measurements see table below. 

 Cranial measurements of type : Greatest length, 16'4 mm. ; basal length, 

 14 ; basilar length, 12-8 ; zygomatic breadth, 8-4 ; least interorbital breadth, 

 2*2 ; mastoid breadth, 9'4 ; greatest length of braincase, 10 ; greatest breadth 

 of braincase above roots of zygomata, 7 ; fronto-palatal depth (at middle of 

 molar series), 3 ; depth of braincase, 5-8 ; maxillary toothrow (exclusive of 

 incisor), 5-6 ; mandible, 10 ; mandibular toothrow (exclusive of incisors), 6, 

 Specimens examined.— Twenty-^Ye, all from the type locality. 

 Remarks. — Though in some respects intermediate between Hipposiderog 

 hicolor and H.fidvus, this species is so readily distinguishable as to need no 

 special comparison.
