When our measurements are compared with those given by E, 

 M. Walker for material from Ontario, we find that some of the 

 specimens from the Severn River show an even greater accen- 

 tuation of the characters of the present race, while those from 

 Toronto show some tendency toward curvicauda curvicauda. All 

 of the material before us from Maine is typical. The single 

 specimen from West Point, Nebraska, though not typical, shows 

 a much closer resemblance to the present race than to curvicauda 

 curvicauda. 



In the series before us the decided lateral angles of the prono- 

 tum are in most cases weakly outlined in brownish white. 



The present geographic race has a limited distribution which 

 borders that of curvicauda curvicauda m the north and northwest; 

 it is laiown from Whitneyville, Maine, to Aweme, Manitoba, 

 being found tj^pical only in the Canadian Zone..
