ICHTHYOLOGY MALACOPTERYGII. KM) 



number of Cyprinidse into one genus, Leuciscus, which 

 have by Heck el been distributed into about 10 distinct 

 genera. It may well be difficult to determine a Fish of 

 this division according to Valenciennes' book. Besides 

 these, there follow the genera Chondrostoma, Cat la (Glbelion, 

 Heck.), Catostomits, Sclerognathus (Catostomus Cyprinus, 

 Lesueur), which appears to be identical with Rhitidostomus. 

 Heck., E.xoylossum. It is impossible here to enter upon 

 the numerous new species. 



Some new CypriniiUe of the genus Barbus have been figured by Smith, 

 ' 111. South Africa,' 14, and arranged in subgenera. Heckel had already con- 

 sidered them, Clieitobdi-'t/'x capensis. \(\\ inch. D. 10; P. 1G ; V. 8 ; A. 7 ;
