I'TKUOPIS LOMBOCIOJSIS (JKOUI*. '^V)0 



leeth, hairing of the upper surface of the tibia, and colour of the fur, 

 as described above. The peculiar tricoloured pattern of tlie upj)er- 

 side (bright head and mantle, dark bac-k, bright rump) characteristic 

 of nearly aJl species of this group of the genus appears to be less 

 constant in Pt. chn/soproctus than in Ft. roi/neri, ruhianus, lavel- 

 lanns, and (jrandis: in some individuals of Ft. chrysoproctus the 

 rump is as pale as, or rather paler than, the mantle, thus strongly 

 contrasting with the dark brown back, while in others it is 

 practically similar in colour to the back, though, at least in certain 

 lights, showing distinct chestnut reflections. Dark-rumped in- 

 dividuals of Ft. vhrijsoproctus are in the colour of the upperside veiy 

 similar to Ft. mdanoporion. which inhabits the same group of 

 islands ; externally they may be distinguished by the more narrowly 

 pointed cars, much broader furred area of the back, much paler 

 sides of neck and forcneck, much darker breast and belly, and 

 smaller size.

H. The PrKfioPcs lohbocexsis group. 



Species. — Four, Ft. lomhocensis, solititrius. vodricensis, and 

 molossinns. 



Faur/e. — Lesser Sunda Islands ; Mascarenes (llodriguez) ; 

 t'aroline Islands. 



Genercd characters (compare fig. 13, p. 270, skull and dentition 

 of Ft. soUt(irkis). — Rostrum short and broad, m^, m\ and ij con- 

 spicuously reduced, i^ one-fourth to one-sixth the bulk of i.,. Ears 

 moderate or quite short ; tibiae clothed above, except in the Caroline 

 species. Colour paler or darker brown above and beneath with 

 ochraceous or buffy mantle, except the Caroline species, in which 

 also the mantle is darkened to brownish. Males with glandular 

 neck-tufts, except the Mascarene species. Size small (forearm 

 94-127 mm.). 



Differentiation of species. — Ft. lomhocensis (Lombok, Flores) and 

 solitarius (Alor) present the cranial and dental characters of the 

 group in their fullest development ; rostrum very short and broad 

 (still more so than in the Ft. raijneri, and quite as in the 

 Ft. samoi'nsis and pselaphqn groups), coronoid portion of mandible 

 heavy, coronoid height subequal to c-m^ ; ra,, m'^, and i^ very 

 small ; dentition heavy for the size of the animals, with distinct but 

 short posterior basal ledges to the premolars ; ears typical Ptero/iine 

 (/iy^w<(*(7((/(*'.s'-like. though somewhat more narrowly ]iointed) ; fur 

 rather short and adpressed ; secondary sexual characters (neck-tufts) 

 well pronounced. The single Mpscarenc species {Pt. rodricoisis) is
