Genus 309. RICHARDSONIUS -« Girard. 



Richardsonius Girard, Proc, Acad. Nat. Sci. Phila., VIII, 1856, 201 

 {Cyprinus (Abramis) batleatns Richardson). 



" The various American allies of LeuciscM Cuvier (type Cyprinun leuciscus L. of Europe, Squnlius), 

 we now divide among several genera, these corresponding to the subgenera in the previous check list. 

 ,\o .si)ecies belonging to Leuciscus, as strictly defined, occurs in America or Asia. Many of the species, 

 both in the groups .illied to Leuciscus and Rulilus as well as in those related to Ilyhopsis and Notropis need 

 comparl.son and verification. 



HichnTdsnnius is here restricted to the single .species, bnlleatus, distingui.shed, with its variant, by the 

 very long anal fin. The genus Cheonda is i)rovisionally recognized for species more or less similar to Rich- 

 ardsonius but with the anal fin shorter. This group .seems to merge into Tigoma. species with tlie anal 

 (in short and the scales rather loosely imbricated. One si)ccies, caurina, forms another intermediate type 

 with short anal and very small scales. Any arrangement of these fishes must be still wholly provisional.
