Diagnosis. — Similar to Ft. aferrimus, but larger, with relatively 

 larger orbits, weaker dentition, and shorter fur on back. Llackish 

 above and beneath, more or less thinly sprinkled -with greyish- 

 white or bnfFy liairs ; mantle dark seal-brown or cliocolate, rarely 

 as bright as hazel. Forearm 160-17n mm. Ilab. Celebes; tSalayer ; 

 Lombok. 



Sknll and teeth. — Skull similar to that of Pt. atr.rrimus, but 

 averaging conspicuously larger; orbits relatively larger: 14*2- 

 14-8 mm., against 13-7-13-U in Pt. aterrimns. — General characters 

 of teeth us m aterrhnus, but dentition on the whole considerably 

 weaker, notwithstanding the larger size of the animal: canines 

 much slenderer, antcro- posterior basal diameter 3'9-4-l mm., 

 against 4-5-4-8 in the adult aterrinms ; ]}^, m\ m^, and m„, 

 though of the same width as in aterrimus, averaging considerably 

 shorter, owing to a still more pronounced reduction of posterior 

 portion (ledge) of teeth ; compare measurements of these teeth, 

 p. 369. In all adult specimens the cheek-teeth are more or less 

 thickly covered with a brownish or blackish coat of tartaric acid. 



Palati-ridijes. — 5-f 5-|-3. Arrangement as in Pt. hypornehinus 

 (p. 101). 



Ears. — Relative size as in Pt. aU-rrnnus (not nearly reaching eye), 

 but upper third of outer margin more distinctly concave, upper 

 third of conch therefore somewhat narrower, and tip more narrowly 

 rounded off. 



Winfjs. — Membranes arising close together from sides of back, 

 separated by a space of about 20 mm. 



Interfemoral. — Distinctly more developed in centre than in Pt. 

 hypnmelanvs. but much less than in the species of the Pt.vam2:)yrus 

 group : depth about 13-14 mm.
