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



might have been included in Pangio ; and very closely akin to it, 

 again, must be the Cobitis micropus, Val., from China, in which 

 the ventral fins are minute,* — but this would appear to have no infra- 

 ocular spine. M. Valenciennes, however, remarks of it—" La caudale, 

 arrondie, a deux carenes charnues sur le dos ou sur la base de la 

 queue, qui semble augmenter la longuear de la nageoire ou simuler 

 une sorte d' adipose." This exactly describes what is seen in our 

 largest specimen of Aptta fusca ; but in the others the ridge is 

 continuous. 0. micropus should constitute another generic coup ; 

 and another again occurs in the Mtsgurna, Lacepede, founded on 

 the European (C.) possiLis.f This last is akin to the first division of 

 Acanthopis, but is still more elongated, subcylindrical, or only a 

 little compressed laterally, and it has no infra-orbital spine, but an 

 indication of the facial slit that conceals the spine in all the preced- 

 ing. It has therefore been held to conduct to the spineless Loches, 

 to which, for the present, I restrict — 



VII. — Cobitis, L. Type C. barbatula of Europe. These never 

 have the head so much compressed as in the majority of Spined Loches, 

 and in some it is even broader than the body : the latter also tends in 

 many of them to be subcylindrical rather than compressed. Some, 

 however, are moderately compressed, approaching to the form of 

 Eotia, but more elongated ; having also a large dorsal fin of many 

 rays : such is — 



C. rubidipinnis, nobis, n. s. A fine species, 4-f in. long, by -§■ in. 

 deep, and \ in. broad ; fully \ in. between the eyes ; from eye to 

 muzzle f in. ; and head from gill-cover •§■ in. ; the dorsal fin nearly 

 1 in. along its base. Six well developed cirri ; and a peculiar charac- 

 ter consists in a short broad obtuse spine-like process projecting from 

 the middle of the upper lip : tail somewhat rounded. General colour 

 olive-brown with a ruddy wash, paler below ; the fins tinged with 

 red ; dorsal and caudal fins transversely rayed with dusky, the other 

 fins without markings. On the dorsal are four or five rows of dark 



* He terms it " la Loche aux petites ventrales." 



f Another, again, perhaps, in certain rather elongated Loches of China, which 

 have ten cirri ; as the C. bifurcata and 0, pectoealis, McClelland, and C 

 anguillicattdata, Cantoi*, figured by Sir J. Richardson in the Zoology of the 

 Voyage of the Sulphur.
