SCIENTIFIC HISTORY OF THE BEACK BASS. 27 



beyond his predecessors, (I) recognizing, for the first time, the generic 

 identity of the forms described by LeSiieur, Cuvier and Valenciennes, 

 and DeKay, (2) retaining for the genus thus enlarged the name 

 Grystes, and (3) recognizing two species as inhabitants of the north ; 

 he was, however, less fortunate in his appreciation of their specific 

 relations, (1) his Gnjstes fasciatus being tlie small-mouthed form, (2) 

 his " Grystes salmoncus " (as is evident from the contrasted charac- 

 ters noticed in his comparison of G. fasciatvs with it) being the 

 large-mouthed southern form, and (8) his Grystes 'irigruans being 

 differentiated without statement of reasons and the Cenirurclivs J'as- 

 ciaius of DeKay identified with it. 



At a later period (1854), Prof. Agassiz distinguished specimens 

 of the genus obtained from Huntsville,* Alabama, as Grystes nohilis, 

 which evidently belongs to the large-mouthed type; the brief notice 

 is only comparative, contrasted with the small-moulhed type, and 

 contains no specific peculiarities. 



In the same year and month (March, 1854), Messrs. Baird and 

 Girardf described specimens of the same type from the " Rio Frio 

 and Rio Nueces, Texas," under the name Grystes nuecensis. This 

 form was subsequently described in greater detail and illustrated by 

 Dr. Charles Girard, in the Report on the Mexican boundary Survey. 



In 1857, Dr. Theodatus Garlick,J of Cleveland, Ohio, in a treatise 

 on tlie propagation of fish, described and published rough woodcut 

 figures of the two forms of the genus: (1) the small-mouthed species 

 under the name "Grystes nigricans ; or black bass;" (2) the other, 

 as a new species, designated "Grystes megastoma ; or large-mouth 



and Animals, compared with those of other and similar regions. . . . Boston;
