56 BOOK OF THE BLACK BASS. 



figure of the large-mouthed Bass (Trout) ever published, is 

 found in his work (Ichthyology of South Carolina). 



In order to show that he clearly miderstood the relations 

 of the Black Bass species, I will quote as follows: — "The 

 Trout has, however, its representatives both in the North 

 and West, with which it is closely allied : as Grystes JSi- 

 gricojis (Hiiro nigr'iGans) of Cuvier and Valenciennes, and 

 Grystes fasciatus [Cychla fasciata) of Le Sueur, both of 

 which have been referred by Agassiz to the genus Grystes."* 

 Dr. Holbrook knew that the southern Trout (large-mouthed 

 Black Bass) was neither Huro nigricans (with its two dis- 

 tinct dorsal fins), nor Gichla fasciata (the small-mouthed 

 Bass). He called the " Trout " Grystes salmoides Lace- 

 PEDE, for he knew that Lacepede's Labrus salmoides, or 

 Bosc's Perca trutta could be nothing else but the " Caro- 

 lina Trout " (large-mouthed Black Bass) ; and, moreover, 

 he distinctly repudiated Cuvier and Valenciennes' complex 

 Grystes salmoides. 



Professor Agassiz clearly recognized the complex char- 

 acter of Cuvier's Grystes salmoides, saying he "probably 

 mistook specimens of our Grystes fasciatus for the south- 

 ern species. "f Professor Agassiz regarded Grystes sal- 

 moides as the projDcr name for the southern large-mouthed 

 Black Bass (Trout), and in comparing with it Grystes fas- 

 ciatus Agassiz, says: "The mouth is less opened and the 

 shorter labials do not reach a vertical line drawn across 

 the hinder margin of the orbits, whilst they exceed such 

 a line in G. salmoides" %
