BATRACHIANS OF KEEWATIN. 



We made a small collection of the species of frogs noted during the 

 trip, and extended their pre\aously recorded ranges. A gradual short- 

 ening of the hind legs as the northern limit of the ranges of these 

 species is approached seems to be the rule, and is evidently correlated 

 with the shorter period of activity. In addition to this collection I 

 include references to several species of frogs and salamanders recorded 

 by Cope from the region about James Bay, and from the mouth of 

 Nelson River. 



Rana pipiens Gmel. Leopard Frog. 



We noted this species at two points — in the meadows near Norway 

 House, where it was fairly common, and at Sea Falls, about 20 miles 

 farther north, where we saw several individuals while we were making 

 a portage. We collected two specimens at each place. 



Eana palustris Le Conte. Le Conte Leopard Frog. 



Cope records specimens from James Bay, collected by C. Drexler." 

 These specimens, which are preserved in the U. S. National Museum, 

 have been re-examined in connection with this report. 



Eana cantabrigensis latiremis Cope. Northern Wood Frog. 



We collected a series of wood frogs that includes specimens from 

 Taft's Fishery (on Great Playgreen Lake), Norway House, York Fac- 

 tory, and Fort Churchill. According to measurements, this series is 

 referable to latiremis as restricted by Howe.* 



Eleven well-grown specimens from Norway House average: Length 

 of body (nose to anus) 46.3; femur (measured from central line) 19.1; 

 tibia 19.9. Seven specimens from York Factory average: Length of 

 body 43.9; femur 18.7; tibia 17.7. A single specimen taken at Fort 

 Churchill measures: Length of body 50; femur 19; tibia 19. 



Cope records cantabrigensis from the mouth of Nelson River, and 

 •from James Bay."" The James Bay specimens have not been critically 

 examined, and may be nearer to cantahrlgensis than to latiremis. 



This frog was by far the most abundant species throughout the 

 region between Lake Winnipeg and York Factory, and many were
