452 INDIAN CYPRINIDZ. 
India, which I have observed upon, p. 262, also seems to have occurred 
to M. M. Hiigel and Heckel, who observe that the Cyprinide have not 
only replaced the Salmonide in the rivers of India, but have also assumed 
much of their habits. In the Nile, they observe, we have few Cyprins, and 
in the rivers of Surinam and Brazils there are none; it is only in the rivers 
of India where Cyprins have replaced the Trouts, (Foredlen) that the number 
of their species is so considerable (Fische aus Caschmir, p. 2.). The species 
described in the work alluded to as Stlurus lamyhur, Heck. differs from 
Silurus pabda, Buch. in the eyes being nearer to the mouth; but in other 
respects it approaches, M. v. Heckel thinks, to Silurus chinois, Lacep ; 
the colour is rusty brown, with a silvery glitter. The next two are Loaches, 
not far removed from the species I have described as Cob. chlorosoma and 
Cob. guttata. They are named by M. v. Heckel Cob. marmorata, and Cob. 
vittata, The first, he thinks, may be Codvtis corica, Buch. and the second 
is named Gurua, by the natives of Cashmeer. A fourth species described 
by M. v. Heckel is referred to the genus Varicorhinus, Riippell, which 
would include those species I have described as Gudgeons when they happen 
to have two cirri; but as cirri are not characters to be alone relied on in 
the formation of groups, it is unnecessary to dwell on the value of this 
genus: those who wish to adopt it, have only to apply the term Varicor- 
hinus to the five first species of Gobio I have described, namely, the Mrigala, 
the Rewah, Curmuca, Reba, and Angra. The one described by Heckel as 
Varicorhinus diplostomus, Fisch. Casch. t. xi., is a new species, somewhat 
resembling, as M. v. Heckel supposes, Leuciscus doubla, but the body is 
more cylindric, and less compressed than any previously known species either 
of India or Europe. 
The sixth species of M. v. Heckel is referred to another nominal genus, 
Labeobarbus, Riippell, which differs in nothing more from the genus Barbus, 
Cuv. than in a fleshy appendage to the apex of the lower jaw, as in Barbus 
progeneius, J. M. t. 56. f. 3. The species given by Heckel as Labeobarbus
