Biacfnosis. — Similar in sknll and dentition to Pt. ■pselapJion and 

 jiiJosus, but with a small cusp-like projection on hinder trenchant 

 margin of upper canine above middle of tooth. Fur shorter than 

 in jnloms, mantle not ])aler than back. Size considerablj' smaller: 

 forearm 119'5 mm. Jlab. ? Vanikoro or JIarianne Is. 



Teeth. — Essentially as in Pt. pitelaphon and pUosus, but some of 

 the chief characters of the dentition in these species (strong deve- 

 lopment of cingiilum in upper incisors, upi)er and lower canines ; 

 enUirgement of i^ and Pj ; tendenc}' in longitudinal ridges of cheek- 

 teeth to break up into tubercles) still more pronounced. — Upper 

 incisors large ; cingulnm excessively strong, forming a broad ledge 

 on ])osterior face of teeth, in i" extending a little beyond external 

 vertical margin of tooth, so as to be visible in front view of incisor 

 as a small basal cusjj on external side. Upper canines long, recurved, 

 stout (as iu inlosus) ; cingulnm as in psehiphon, subdivided into a 

 series of small tubercles ; a small, -well-marked eusji-like projection 

 on posterior trenchant edge of canine above middle of tooth. Inner 

 longitudinal ridge of m' and mj with pronounced tendency to break up 

 into small, rounded, incompletely differentiated tubercles. — i., very- 

 large, between four and five times the bulk of i,. p^ uniianally 

 largo, larger than i„ and more than twice the size of m^. — Other 

 characters as in pselitphon and pilosus. 



Pur. — As in Pt. pilosus, but rather shorter: approximate length 

 of hairs, back 16, mantle IG mm. Upperside of tibia covered for 

 proximal half or two-thirds. 



Colour. — The type and only skin known (Paris ^Jlnseum) is 

 jirobably faded by exposure to light. In its present condition 

 the whole pelage above and beneath is some shade of russet-brown, 

 darkest (almost vandyck-browu) on mantle, sides of neck, foreneck,
