a verj' short lower limb. The length of the pectoral is less than one-

 verj' smaU. Caudal deeply forked, the length of its middle rays 

 being one-thii-d of that of the longest. Body and caudal fin covered 

 ■with round pale spots of moderate size. 



Richardson says that this species is common in every river and 

 lake from Canada to the northern extremity of the continent ; but 

 we have shown above, that he evidently confounded several species 

 under this name. Our two specimens are probably from Boothia 

 Felix.
