the teeth deeply serrated, whilst in the latter they are said to 

 be entire. It seems doubtful whether the divisions based on 

 this character are more natural than those founded on the 

 presence or absence of spinous rays in the dorsal and anal 

 fins. The recently described Acanthorhodeus gracilis, Regan 

 (P. Z. S. 1908, p. 60), from Corea, has the pharyngeal teeth 

 distinctly but not deeply serrated. 



Barilius grahami. 



Dorsal fin with 7 branched rays, anal with 11. About 60 

 scales in a longitudinal series. In other characters extremely 

 similar to B. polylepis, Regan, and B. andersoni, Regan. 



Hah. Chenkiang Lake, 90 miles S.E. of Yunnan Fu. 



Six specimens, which had been dried, 100 to 120 mm. in 

 total length. 



Nemachilus oxygnatltus. 



Depth of body 8 to 9^ in the length, length of head 5 to 5£. 

 Snout as long as postorbital part of head. Diameter of eye 

 6 in the length of head, a little greater than the interorbital 

 width. Breadth of head 2 in its length and more than its 

 depth. Mouth formed as in JS. berezowskii, Giinth., the 

 pisemaxiilaries forming a pointed symphysial projection; 

 maxillary barbel 1| the diameter of eye. Valve between the 

 nostrils produced into a short barbel. Body covered with 

 small scales behind the level of the dorsal fin ; further forward 

 rudimentary scales on the sides ; lateral line complete. 

 Dorsal 11, with 9 branched rays; origin nearer to end of 

 snout than to base of caudal ; longest ray shorter than base 

 of fin; free edge slightly convex. Anal 7, with 5 branched 

 rays. Pectoral extending about ^ the distance from its base 

 to the pel vies, which are 8-rayed, are inserted below the first 

 branched ray of the dorsal, and extend about \ of the distance 

 from their base to the origin of anal. Caudal rounded. 

 Caudal peduncle nearly as long as or a little longer than the 

 head and about twice as long as deep. Body with 15 dark 

 brown cross-bands, about as wide as the interspaces between 

 them ; 5 bands on the caudal region ; dorsal rays with 2 or 3 

 series of dark spots. 



Hob. Yunnan Fu. 



Two specimens, 102 and 131 mm. in total length. 



The closely allied N. berezowskii, Giinth., 1896, from 

 Southern Kansu, has a shorter head (6 in the length) and 

 more numerous cross-bands (9 on the caudal region).
