The specimen selected as the type differs a httle from 

 Cope's account. Head said to enter length to caudal a little 

 over 4 times ; depth 4 3/4 ; eye 3 ; dorsal inserted nearer end 

 of muzzle than caudal base. A small label, evidently in Cope's 

 handwriting, says "one specimen P. notatus"^' Also a large 

 number of young examples, evidently the present species, 

 from Grosse Isle and Houghton Lake.

 above cotypes are identical specifically and I do not find P. notatus from Grosse 

 Isle.
