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

 nasuta, wbich is a large-scaled Cyprin altogether distinct from 

 Balitora of Gray, which Mr. McClelland most unaccountably unites 

 with his Platycaea) : # Bangana, Gray (nec B. Hamilton) ; com- 

 prising Discognathus, Heckel ; and the more typical Indian species 

 doubtfully referred to Lobooheilos 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 Ricn-oehynchus (as adopted by him), with- 

 out perceiving that his Platycaua nasuta and also his Pl. lisso- 

 rhyncha strictly belonged to it, equally with other species which 

 he has figured in As. Bes. XIX, pl. Lili, in sorne of which the face 

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

 trated also by the Discognathus fasifonnis, Heckel, of Barón Hugel's 

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

 form may be cited the Gyprinus (Bangana) falcata and G. gotyla, 

 B. H., of Hardvvicke's Illustrations of Iridian Zoology : but all shew 

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

 have seen having Kkewise 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, exempliñed by the Gobio ricnoriiynchiis 

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

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

 genera is repeated in Cale. Journ. N. H., Vol. II, p. 587, and pl. XVI ; where 

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

 cara lissoehyncha, and a true Balitoea as Pl. anistxeus !
