I had referred an imperfect specimen of this fish, obtained in Lake Huron, to 

 C. Hudsonius, but after examining several very well-prepared examples from 

 Albany River, I think it probable that it may prove to be a distinct species. If, 

 on a comparison of the recent fish, this question be decided in the negative, Cuvier's 

 specific name must give place to Le Sueur's prior one of Hudsonius. 



The head is less convex at the eyes, the eyes themselves are farther back, the mouth is a 

 little smaller, and the depth of the body somewhat greater than in C. Hudsonius ; but the 

 length of the head, which does not form a fifth part of the whole length of the fish, and the 

 other external proportions, are the same as in that species. The scales, however, which are more 

 distinctly radiated and crenated, exhibit in the prepared specimens of the younger individuals 

 a nearly uniform hyacinth-red tint ; and in the older ones reddish-orange tips with dark grey 

 bases, forming a coloured mesh-work, whence the specific name. The belly is pale. The 

 scales of the lateral-line vary in number from 70 to 77, and there are 18 or 20 in a vertical 

 row under the dorsal.

By the acquisition of three well-prepared specimens from the Albany River 

 district, Hudson's Bay, I am enabled to give the dimensions of this fish more fully.
