UTAT. Columbia River. 



Only the original type of this species is known. It is an adult spe- 

 cimen, well preserved. Although this species seems closely related to 

 C. Occident a I is, I am disposed to consider it distinct, as the mouth is 

 notably larger than in any occidentalis which I have seen. The exami- 

 nation of a large series of specimens may, however, render it necessary 

 to unite them.
