452 INDIAN CYPRINID^. 



India, which I have observed upon, p. 262, also seems to have occurred 

 to M. M. Hiigel and Heckel, who observe that the Ci/prmidce have not 

 only replaced the Salmonida 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, (Forellen) that the number 

 of their species is so considerable (Fische aus Caschmir, p. 2.). The species 

 described in the work alluded to as Silurus lamyhur. Heck, differs from 

 Silurus pahda, 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 Cobitis 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 doid)la, 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
