160 Report on some Fishes received from the Sitang River. [No. 2, 



fin towards ks base. Lateral line very indistinct from below the 

 commencement of the dorsal. 



D. 3-8.— A. 2-5 ? 

 About 24 scales longitudinally, and 8 or 9 obliquely downward 

 from the dorsal. Largest specimen but If in. Tenasserim. 



Genus Platycara, McClelland (as originally founded on his Pl. 

 kasuta, which is a large-scaled Cyprin altogether distinct from 

 Balitora of Gray, which Mr. McClelland most unaccountably unites 

 with his Platycara) :* Bangana, Gray (nee B. Hamilton) ; com- 

 prising Discognathus, Heckel ; and the more typical Indian species 

 doubtfully referred to Lobocheilos by Dr. Bleeker. A genus of 

 Gudgeons inhabiting mountain rapids, the more characteristic species 

 having a great transverse cleft on the face studded with large tubular 

 pores, and also an adhesive disk to the lower lip, — which group Mr. 

 McClelland referred to Ricnoehynchus (as adopted by him), with- 

 out perceiving that his Platycara nasuta and also his Pi. lisso- 

 rhyncha strictly belonged to it, equally with other species which 

 he has figured in As. Res. XIX, pi. LI LI, in some of which the face 

 is smooth and not cleft and the labial disk is greatly reduced, as illus- 

 trated also by the Discognatlius fusiformis, Heckel, of Baron Hugel's 

 Fauna von Easohmir (p. 378). As examples of the more typical 

 form may be cited the Cyprinus (Bangana) falcata and 0. gofula, 

 B. II., of Hardwieke's Illustrations of Indian Zoology : but all shew 

 a strong tendency to the Balitora form of pectorals; all that I 

 have seen having likewise large ventrals, and the backward position 

 of the mouth which opens downwards, and fimbriated anterior lip, 

 seem to be of constant occurrence. The cleft and tubercular face 

 occurs in another type, exemplified by the Gobio ricnorhywchits 

 of McClelland, which (so far as I know at present) stands quite 

 alone, as a particular type worthy of a special designation. f The

 pi. LYII, /. 2, with a and b. The mistake of uniting these two incongruous 

 genera is repeated in Calc. Journ. N. R., Vol. II, p. 5S7, and pi. XVI ; where 

 a species of the mountain type of Gudgeon is described and figured as Platy- 

 cara lissorhyncha, and a true Balitora as Pl. anisttrus ! 



f Perhaps true Lobocheilos ? It approximates the Tyloehynchfs, Heckel, 

 but the duplication of the lips and great chin-pore are peculiar. To Tiloo-
