Apparently similar to the European Uranidea gobio, and distin- 

 guished from most of the American si^ecies by having the ventral rays 

 1, 4. Skin smooth; pectorals as long as head; preopercular spine small 

 curved upwards. D. VIII-18; A. 14. Great Bear Lake {Bichardtion); 

 perhaps the same as the next.
