Rana septentrionalis 413 



inches from snout to vent, or little below the two largest specimens which 

 were taken (49 mm. or 2 inches). The other specimens which were not lost 

 measured 47, 42, 42, 43, 40, 40 mm. respectively." At the time I did not 

 sense it but these eight were doubtless little past transformation. 



On August 8-9, 191 7, Pope (Copeia, Dec. 31, 19 18, p. 96) found tadpoles 

 transforming and transformed at Tim Pond, Eustis, Franklin Co. Me. 

 "Most of the tadpoles had completed their transformation before this date 

 but I collected a single one with large hind legs, measuring i 15/16 inches 

 including the tail. Most of the frogs found had evidently completed their 

 change this summer and some retained the stump of a tail. They averaged 

 13/4 inches long, snout to vent. The adults of which I collected four, were 

 nearly twice this size 2 15/16 inches." 



In a group of 60 or more specimens taken the middle and last of August, 

 1 9 19, Mr. S. E. R. Simpson has three just transformed at 32, 35 and 36 mm. 

 This summer (1923) from tadpoles from Onekio, I have two transformed on 

 July 2, two at 30 and 34 mm., and one July 14 at 29 mm. We, therefore, 

 have transformation from June 24 (Garnier) to the last of August (Simpson) 

 at from 29-38 mm. or possibly to 40-49 mm. I believe that sometimes after 

 real transformation they retain the tail for a considerable period. The bulk 

 of transformation doubtless comes in June and July.
