Color, ill spirits, dark brown; vertical fins edged with darker; lat- 

 eral line dark. 



This species seems to be distinguished from insignis chiefly by the 

 much shorter spines, by a slight difl'erence in coloration, and by the 

 more robust body. This species is described from a single specimen, 

 4f inches long, taken at Napierville, Ills., by Dr. Ernest E. Copelaud. 

 The type (No. 29G77, U. S. Nat. Mus.) has been i^resented by Professor 

 Jordan to the United States National Museum.
