CYPRINID^ OF EASTERN CANADA. 45 



are the smallest known to the writer, never exceeding two and 

 three-quarters inches in length. This diminutive form seems to 

 represent the western type, which, it is said, never exceeds three 

 inche 1 though it differs from it in many ways. The anal fin is 

 mostly 9 instead of 8-rayed ; the dorsal insertion more posterior 

 by two-thirds the length of the caudal ; branchial Ic-iflets oblong 

 and stouter ; gill-rakes shorter, less acute and with broader 

 bases ; snout shorter and blunter ; lateral line relatively longer, 

 and the band on the side intensely black in life and forming a 

 conspicuous patch on the operculum. 



The fish of McDonald Lake are h\\\y five inches long, and are 

 ])eculiar in that the females are more rosy in the breeding season 

 than the males. 



The Gaspe Phoxinus is very close to the larger New Bruns- 

 wick form, being about four inches in length, but the dorsal and 

 anal are more pointed, the pectoral longer and muzzle more 

 acute. It seems, too, to be less brilliantly colored. The denti- 

 tion, however, is very irregular. 



The writer is not aware that Phoxinits occurs anywhere else 

 in the Dominion of Canada.
