NOMENCLATURE AND MORPHOLOGY. 97 



and assumes a shape somewhat like that of some of the Grey- 

 lings. Tlie tail is shaped a good deal like the Salmoidce, and in 

 this fish has a dark bar across the center." — (Jardine, Nat. Lib. 

 I, Perches, 158, 1835.) 



CiCHLA FA8CIATA and CiCHLA OHiENSis Kirtland, 1838. — 

 "The Black Bass of the Lake and of the Ohio River. Le Sueur 

 has described them as distinct species. I have no doubt they 

 are specifically identical. They differ in form and color at differ- 

 ent seasons and in different localities, and even the same in- 

 dividual will change its color repeatedly in a short space of time 

 if confined in a vessel of water. 



" Rafinesque has described that from the Ohio under the 

 generic name of Lepomis, and taken these changings of color as 

 a distinction upon which he has founded several of his species. 

 His Lepomis notata is no other than the young of the common 

 Black Bass. Their appearance varies at different ages. 



"This fish readily bites at a hook, and is valued as an article 

 of food."— (Kirtland, Rej^t. Zool. Ohio, 191, 1838.) 



CiCHLA MiNENiA Kirtland, 1838. — " Le Sueur describes this 

 as an inhabitant of Lake Erie. I am suspicious it is only the 

 young of the preceding species, as I have never been able to find 

 it, though I have searched repeatedly in the lake and its trib- 

 utaries." — (Kirtland, Rept. Zool. Ohio, in 2d Geol. Rept. Ohio, 

 191, 1838.) 



Centrarchus fasciatus Kirtland, 1842. — "This species 

 presents such a variety of forms, colors and habits, and is so 

 much influenced by age, sex, seasons and locality, it is not re- 

 markable that its varieties should have been described as dis- 

 tinct species. Still I am convinced that the synonyms I have 

 enumerated embrace only one true species (these are Lepomis 

 pallida, trifasciata and flexuolaris, Raf. , Icth. Ohiensis, p. 30, 31; 

 Etheostoma calliura Raf, Icth. Ohiensis, p. 36; Qchla fasciata
