3. ORTHRIAS Jordan and Fowler. 

 Orthrias Jordan and Fowler, new genus (oreas). 



Allied to JVer/uwhet'lus Van Hasselt. 



Body elongate and compressed. Head sometimes depressed, and 

 with the dorsal profile nearly horizontal; no spine below eye; mouth 

 small, inferior, and with flesh v lips: barbels 6, none on the mandible. 

 Dorsal fin short, and situated over the ventrals. Ventral ravs 8. Air 

 bladder more or less inclosed in a bony capsule. Caudal rounded or 

 truncate, not forked. Lateral line complete. Fresh waters of Eastern 

 Asia, the species apparently numerous. 



This genus is related to Nemache'dm^ but the original type of that 

 group {y. fasclatm) has about 13 dorsal vays and the caudal forked. 

 The Japanese species with a short dorsal and a truncate caudal is 

 therefore made the type of a distinct genus, Orfhr/as, to which numer- 

 ous Chinese and other Asiatic species apparently also belong.
