27S PROCEEDINGS OF THE ACADEMY OF [April, 



1. 1. ; usually 15 predorsal scales, occasionally 14, 16 or 17; snout 

 3f to 3f in head; eye 3& to 3f; maxillary 3 to 3f ; interorbital 2f to 

 3; teeth 2. 4-4, 2; length 3A to 4f inches. Ten examples from 

 Sparrow Lake in Simcoe County, Ontario. 



Originally this form was thought allied with N. cornutus, but its 

 dark caudal spot, slightly imbricated lateral scales and fewer anal 

 rays point to its present location. The original account 7 differs in 

 giving the depth 4£, 4 scales above 1. 1. and 3 below. Dr. B. W. Ever- 

 mann kindly examined examples from Garden Isle in Lake of the Woods 

 and Rapid River. Minn. They show the head about 4^ to 4£, 

 depth about 3 T \ to 4 T \, 5 scales above 1. 1., 4 scales below 1. 1., snout 

 about 3 to 3£, eye about 3 to 3i, teeth (in 2 examples) 2, 4-4, 1, and 

 length of largest about 3| inches. He writes "the only tangible 

 difference, so far as these measurements show [from the typical hud- 

 sonius], is the length of the head, the selene type having a considerably 

 shorter head than the others. There is no difference in the fins or 

 scales." I have since examined several of these Lake of the Woods 

 examples, now in the Academy, and think they are younger examples 

 of selene, and that the size of the head is largely due to age.
