XCU SYNOPSIS OF GEUEKA. 



Indications are not wanting that the Megachiropteran fauna of 

 the Carolines, spread as it is over many islands covering a large 

 area, may fall into at least two sections. Thus, the Pteropus 

 marianyius group is in the extreme west represented by one species 

 (yapensis), in the extreme east by a clearly distinct species 

 (ualanns) ; iihe Pte7'opus j^selaphon gronp has so far been recorded 

 only from two places in the Carolines, the Ituck Atoll and Mortlock, 

 but specimens from the former {insularis) seem to differ from the 

 single available specimen from the latter (phceocephalus).

 Megachieopteka. 



I. Molariform teeth not multicuspidate ; lower 

 canines not proclivous. 

 A. Tongue simple : tixed to floor of mouth 

 by posterior half, and without uufriuged 

 filiform papillse at tip (figs. 65 A-H, [p. 1. 



p. 725) I. PTEROPODIN^, 



a. Facial axis of skull conspicuously de- 

 flected against basicranial axis : alveolar 

 line, if projected backward, passing 

 through middle or upper edge of occipi- 

 tal condyle or even through some point 

 of supraoccipital [Rousetti;s section.] 



«'. Incisors never j — ^, lower canines nor- 

 mal in position, cheek-teeth ^ or (in 

 Styloctenium only) ^ ; cranial rostrum 

 not shortened, premaxilla? not more 

 reduced than usual ; second finger 

 clawed. 

 a'. Occipital (sublambdoid) region of skull 

 not elongate ; a short tail (third meta-
