Diagnosis. — Allied to Pt. dohsoni, but orbits larger, i., and p^ 

 smaller, cheek-teeth slightly smaller, ears longer and more dir,- 

 tiuctly attenuated above, general size sliglitly smaller, tibia much 

 i.hortcr, and colour of head, mantle, and underparts much paler. 

 Back and under.side of body dark brownish thickly varied with 

 silvery buffy or buify straw-yellow, the ])ale hairs sometiraea nearly 

 concealing dark colour on underparts ; head and neck ochraceous 

 or ocbraceous-buffy : a mars-brown phase occurs. Forearm 135- 

 1. 39-5 mm. Hah. Gilolo group; Sula Is. ; Sanghir Is. 



Skull.- — Similar in size and other characters to that oi Pt. dohsoni, 

 but with conspicuously larger orbits ; orbital diameter 14*2-14"7 

 mm., against 13 in Pt. dohsoni. — In size the skull of Pt. caniveps 

 equals that of the largest races vi Pt. hypomelanus, from which it 

 differs chiefly in the heavier, particularly broader, rostrum, broader 

 palate, and larger orbits; ma\illary width across external sides 

 of m^-m' 20-2-20-8 ram., against 16'5-19 in all races of Pi. hypo- 

 melanus ; width of mesopterygoid fossa 8'2-8'7 mm., against 

 7-8-2; width of palate between p^-p^ 12 mm., against 9-11-7; 

 orbital diameter 14-2-14-7 mm., against 12-7-13-2. 



Teeth. — Not quite as heavy as in Pt. dohsoni, and with con- 

 spicuously smaller i, and p,. Similar in structure to those of 

 Pt. hypomelanus, but canines longer, cheek-teeth markedly broader 

 (compare measurements, p. 199, with those of Pt. hypomelanus, 

 pp. 118 and 131). — Ciugulum of upper and lower canines narrow. 

 Posterior ledges of upper and lower premolars short and ill-defined, 

 thougli a minute postero-external basal notch is occasionally detect- 

 able in p' and p^. m'- larger than m^. i^ once and a half or nearly 

 twice the size of i^. p, once and a half the size of i^, subequal 

 to ni.
