Habitat—Pennsylvania to South Carolina. This species was first 
noted by Le Sueur under the name of Pimelodon livrée, but for some 
reason that author neglected to give it a classical name. The name of 
insigne was supplied by Richardson, and that of lemniscatus by Cuvier 
and Valenciennes. The description of the coloration is such as to leave 
no possible doubt of the identity of this species with Le Sueur’s. 
No satisfactory description of this common fish has yet been pub- 
lished. It is well distinguished from miurus and exilis by the char- 
acters given above in the analysis of species. 
25. NOTURUS EXILIS, Nelson. 
Slender Stone Cat. 
(Figs. 58 and 59.) 
Noturus exilis, NELSON (1876), Bull. Ills. Mus. Nat. Hist. 51—Jorpan & COPmLAND 
¥ (1876), Check List, 160.—JorpDaN (1877), Ann. Lye. Nat. Hist. N. Y. —. 
Habitat.—Wisconusin and Illinois to Missouri and Kansas. 
The synonymy of this species needs no remark. Its relations are 
entirely with marginatus, from which species it is undoubtedly distinct. 
Specimens from Wisconsin are much less elongate than Nelson’s original 
types. I do not, however, consider them specifically distinct. 
26. NOTURUS MIURUS, Jordan. 
Variegated Stone Cat.
