igii.] B. L. Chaudhuri : The fauna of Yunnan. 17 



and 10 rows of scales from the posterior root of anal fin to the 

 inferior terminal ray of the caudal. The second ray of the anal is 

 ossified and the outer free margin of the fin is concave, that of the 

 ^'entral being slightly convex. 



Lateral line. — Commencing on the superior corner of the gill- 

 cleft it drops down graduall}^ through eight rows of scales to 

 above the end of pectoral fin from which point it almost runs as a 

 straight line to end at the middle point of the root of the caudal 

 fin. There are three and a half rows of scales between the lateral 

 line and the ventral fin and six and a half rows between the lateral 

 line and the anterior root of the dorsal. In the caudal peduncle 

 there are generall}^ eight rows of scales, four rows above and three 

 rows below the row in which the lateral organs are situated. 



Colour. — Upper one-third including head brownish, the rest 

 silver5^ Fins pale yellow, the ventral being of a slightly deeper 

 colour. The ends of rays of dorsal and caudal slightly touched 

 with grey. In some there is a circular deep brownish or golden ring 

 in the middle of the eyelid. The barbels are brown. 



Hah.—ha.liQ Tali Fu, 7,000 ft., Yunnan. Four full-grown 

 specimens: F. *^y^-^ is a mature female, 102 mm. in length with 

 caudal; F. ^^^-^-, female big in roe, 154 mm., total length with 

 caudal ; F. *6-«-5, total length 133 mm (damaged) ; and F. i^-^. ig 

 a female big in roe, 148 mm., with caudal (figured). 



The new species differs considerably from the two others of 

 the same genus described from Yunnan, i.e., B. grahami, Regan, 

 andB. yunnanensis , Regan, and also from B. oaiesii, Blgr., and B. 

 compressus, Blgr., of the vShan vStates. It has some resemblance, 

 however, to Barhus clavatus (McClelland) from Sikhim, which is very 

 imperfectly described from a single specimen known, and also to 

 Barbiis ;»ai'gtTna;zw5, Day, from the Nampoung river in the Kakhyen 

 Hills (Bhamo), but from each of these it differs in a good many 

 important particulars some of which are detailed below : — Length 

 of head in the total length is 6^ in B. mar gar i ami s , 4f in B. 

 yunnanensis, 3|- in B. grahami and 3| in B. clavatus, while it is 

 3| to 31 in the new species. Length of snout in the diameter 

 of eye is 2 in B. grahami, if in 5. yunnanensis , i^ in B. margaria- 

 nus, while it is only r in the new species. Two pairs of barbels are 

 equal in length in Barhus clavatus but in all other species men- 

 tioned above, including the new species, they are unequal, the 

 anterior pair being f of head in B. grahami, ^ in B. yunnanensis 

 and nearly i of head in the new species. In B. clavatus the snout 

 is covered with thorny tubercles, and in B. margarianus there are 

 large open pores on the front and sides of the snout, while that of 

 the new species is exceptionally smooth. In B. clavatus none of 

 the anal rays are prolonged but in the new species the anterior 

 rays are longer than the posterior rays. In B. margarianus the 

 abdominal profile is more convex than that of the back, in the 

 new species the abdominal profile is almost a straight line. The 

 mouth is anterior and terminal in the new species, whereas it is 

 subterminal both in B. grahami and B. yunnanensis.
