266 PTKKOl'US r.OMBOCENSIS. 



characterized by the conspicuously smaller size of the teeth, whicli 

 however show the principal characters of the lombocensis dentition 

 fully developed (reduced ID3, m", and i^), the considerably heavier 

 posterior basal ledges of Pg, p^, and ni^, and the more distinctly 

 differentiated antero-internal base of p\ p\ and m^ ; probably owing 

 to the smaller teeth, the coronoid process is lower and more sloping, 

 the coronoid height of the mandible less than c-ra^ ; ears reduced 

 (as in all species inhabiting the Mascarcnes), fur longer and more 

 spreading (also a character common to all Mascarene species) ; 

 colour .similar to that of Ft. lombocensis, but brownish of back and 

 underparts ratlier darker, ochraceous of mantle richer. The prin- 

 cipal modifications exhibited by the single Caroline species of the 

 group (Ft. molossimis) are the unusually small, subsquarish cheek- 

 teeth (weak coronoid process), peculiarly trenchant edges of the 

 upper canines, relatively large p^ (compare the Ft. samoensis and 

 pselaplion groups), small ears, rather long fur, naked tibia, nearly 

 uniform dark brown colour (compare Ft. anetianus and pselajJion), 

 and verj' small size. 



Affinities of group. — Ilather closely related, on the one hand (and 

 probably most intimately) to the Ft. rayneri group, with which it 

 accords iu the short and broad rostrum (but the character is still 

 more pronounced in the lombocensis group) and reduced m^ and m", 

 on the other hand to the Ft. sanioensis and pselaphon gi'oujjs, which 

 it closely resembles in cranial characters. That the four known 

 species inhabit so widely separated areas as the Carolines, Lesser 

 Sunda Islands, and Mascarenes, is evidence that they are the few 

 survivors of a formerly much more generally distributed type of the 

 genus.
