liALTONYCTEUrs MACUIATA. Q57 



In Other respects it is peculiarly specialized, viz. in the complete 

 disappearance ot the posturbital foramina (as in C/nwlav 

 Ikoopten., Peatketor, and Spk.ru.s), the suppression o , and 

 shortening of r (characters developed independently in different 

 Cyuopterme genera, seep. 649, footnote), thereduction of m' m and 

 nr, (as HI GJnrona,^) the development of an antero-external bLal'lobe 

 in p^ (represented by a cusp in Cku-ona.), the absence of a tail ( s 

 mClurona.v), and the unusually large wings (character present, to a 

 Is degree, in CInronax). Its closest known relative is the Ja'-an 

 Uuronax. Bahonycteris and Nycthnene are the only Fruit-bats 

 with sharply-defined yellow spots on the membranes.
