11. HAEPIOCEPHALBS. 277 



Muzzle elongated, conical ; ^lostrils prominent, tubular, produced 

 beyond the upper lip, opening laterally or sublateraUy, emarginate 

 between; crown of the head scarcely raised above the face-line; 

 ears thin, generally covered with glandular papillse; tragus long, 

 attenuated towards the tip, and inclined outwards; thumb very 

 large, with a large strongly curved claw; wings broad, from the 

 base of the toes or attached along the outer toe as far as the base 

 of the claw ; iuterfemoral membrane very hairy, or half-covered 

 above. Skull thick, not vaulted ; coronoid process of the mandible 

 much developed vertically. 



Deritition. Inc. ?^, c. \~\, pm. |^, m. ^^ 



Upper incisors on each side parallel, stout, and blunt ; posterior 

 upper molar small or consisting of a thin transverse lamina of bone, 

 and sometimes absent in the adult. 



The peculiarly shaped elongated tubular nostrils are at once cha- 

 racteristic of this genus. In no other genus of Bats, except Harpyia 

 (Pteropodidce) is this peculiar elongation of the nostril beyond the 

 muzzle found. In the different species the form and direction of 

 the nasal tubes vary within short limits, but the general characters 

 are the same. 



Harpiocephcdus is evidently more closely allied to Kerivoula than 

 to any other genus, and appears to occupy a position with regard to 

 that genus similar to that occupied by Vesperugo with regard to 

 Vespertilio. 



Range. From the Himalaj'as to the Malay archipelago, inhabiting 

 hill tracts.
