((16 PTEROPTJS feiCAPULATCS. 



brown and soul-brown (darkest extreme) : concealed baae of fur 

 generally paler, wood-brown or mars-brown. Flanks usually 

 similar to breast and belly, sometimes slightly more washed with 

 mars-brown. Hair on underside of membranes pule straw-yellow, 

 strongly contrasting with dark underside of body. — ilantle varying 

 from rich cinnamon, through rich russet, to nearly burnt-umber, 

 these tinges confined to short tips of hairs ; base of fur much paler, 

 buffy, ochraceous-buffy or buffy clay, generally more or less 

 incompletely concealed by darker hair-tips. Narrow spinal tract 

 of mantle in some specimens distinctly darker (darker-tipped) than 

 lateral portions of mantle, producing an ill-defined spinal stripe, 

 dividing mantle into a right and left half (" shoulder-patch," Peters ; 

 hence probably the name scaj^ulatus). Sides of neck, foreneck, and 

 throat essentially like mantle, but generally of a rather darker 

 tinge, (ilandular neck-tufts (in males only) varying from yellowish 

 buffy to deep tawny.— Colour of mantle extending forward to, or 

 sui rounding base of, ears. Rest of head and face, above and on 

 sides, similar to back, but generally more conspicuously grizzled or 

 powdered with hair-brown. 



Sexual di/ferentiation. — A thick tuft of rigid glandular hairs on 

 each side of ucck in males, wanting in females; hairs of mantle in 

 a broad transverse belt between right and left neck-tufts more rigid 

 and unctuous in males, softer and more spreading in females. 

 Canineti heavier in males than in females.

litinije. N. Q.ueensland, from Thursday Island, southward at 

 least to llockhampton ; Arnhemland ; Kimberley Division. 

 Ti/pe in the Berlin Museum. 



J'teroims scapukitus, Vfters : 1862. — Type, 2 ad., mounted skin, 

 skull separate, Cape York, bought of Frank; Berlin Museum 

 110.1^616. Skull of type figured in ' Megachiroptera des Berliner 

 Museums ' (/. s. c). 



J'ter;)/iu.i eheiji. Gray ; 1866. — Type locality, Claremont Islands, 

 N.E. Queensland ; type in collection. Peters's description of 

 Pt. scojiid'jlus was not unknown to Gray, who, however, considered 

 (,liat Dpecies allied to, if not identical witli, Pt. poliocephaliis (Cat. 

 Monk. &c. p. 105; 1870). 



llemarlcs. — Pt. scapulatus is readily distinguished from any other 

 known species of the genus by the combination of these two 

 characters: cheek-teeth excessively narrow, ears long and pointed. 

 It is the only medium-sized (forearm 131-143 mm.) species with 

 degenerated cheek-teeth, the three other species of this genus 

 with similarly reduced teeth, viz. Pt. sithniger, personaius, and 

 woodfonii, beitig very small (forearm 86-99 mm.). In the Solomon 

 Islands it is represented by a closely allied, but short-cared species, 

 Pt. woodfordi.
