cTcated a new genus, l'((c7it/so)iia I name preoccupied), for tlie three 

 rlosest relatives of mctryiiKdus, viz., iliardi (probabl\- = s. iitthce- 

 cheilus), titth(vcheihts (may be fixed as type of his I'aclujsoma), and 

 duvaucell (probably = brachyotis), and his description of Fachysoma 

 is practically identical with that given by F. Cuvier of Cynopterus ! 

 The result was, of course, that of the subsequent writers some 

 (Is. Geoffrey, Temniinck, Peter.i in his earlier papers) accepted 

 Fachysoma as a name of the present genus ; others (Desmarest, Gray, 

 Peters in his later papers) Cynopterus ; while others again {e.y. 

 Lesson) accepted both genera, viz., Cynopterus for mnrginatus only, 

 and Fachysoma for the other species known. A further confusion 

 arose when Temminck in his latest publications (1853), and after 

 him Wagner (1853-55), extended the genus Fachysoma to comprise 

 both the present genus and Epomophorus (in spite of the diametri- 

 cally opposed cranial characters of these genera, but pi'esumably 

 owing to the fact that the number of cheek-teeth is reduced in 

 both). It is only since Peters 's revision (1867) and Dobson's 

 Catalogue (1878) that Cynopterus has been definitely recognized as 

 the proper name of the present genus. — Quite recently it has been 

 l)roposed to separate in a distinct genus {Niadius, Miller, 1*J06) 

 those species of Cynopterus which possess a well-developed surface 

 cusp in p^ and m^. A glance at the table p. 590 will show that 

 this character is far from being of generic importance. 



Synopsis of the Species, 



A. Cheek-teeth narrower, oval in outline ; 

 surface cusp in p^ and ui, small or 

 entirelj' absent. (Cynopterus section.) 



a. Ears relatively longer, 18-20-5 mm. 



from orifice. Forearm 66-83 mm. 

 (Ceylon ; Indian Pen. ; N. Siam ; 

 Sumatra ; Java ; Lombok) 



b. Ears relatively shorter, 13-18 mm. 



from orifice. 

 a' . Smaller : forearm 54'o-72 mm. 

 (Indo-Malayan subregion, W. to 

 Ceylon, N. to Assam, E. to 



Celebes) 



b'. Larger : forearm 75'5-82 mm. 



(Nias) 



B. Cheek-teeth broader, subrectangular or 

 subsquarish in outline; surface cusp of 

 P4 and mj always present and well- 

 developed. {Kiadius section.) 



c. Size medium : forearm 64'.5-77'o mm. 

 c'. p4 and m, quite as broad pos- 

 teriorly as anteriorly. (.Java ; 

 Sumatra) 



d'. Pj and m, conspicuou.sly nar- 

 rower posteriorly than an- 

 teriorly. (.Malay Pen.) 



d. Larji;est species of genus: forearm 



84-5-890 mm. (Nias)
