158. Amiurus marmo7-atus {Rolbvook) J ordsin. Marbled Cat. (M. V. 

 332.) 



Numerous specimens of a cat-fish, marbled in color, and not ev- 

 idently distinguishable from .4. mannoratus, Holbrook, were col- 

 lected by Professor Forbes in southern Illinois, and one or two 

 from Illinois River. Considerable variation is shown in the col- 

 oration, some being nearly plain, others much variegated. In one 

 specimen, the broad head with depressed front much resembles 

 that of A. xanthocephalus. In all the adipose fin is very large 

 and the dorsal spine is quite high. Henry, 111., Johnson Co.

 tion,) but have been identified with catus by Dr. Jordan. S. A.
