26 FAMILIAR LIFE IN FIELD AND FOREST. 



The nose of this species is more obtuse than that 

 of Eana virescens vi7'escen.^, and the general color of 

 the back is light brown, well covered with ohlong 

 spots of darh brown regularly arranged on either 

 side. Between these spots and another similar series 

 lower down on the side is a bright yel- 

 low line. The wood frog's color is 

 generally tan brown, but he is 

 without conspicuous spots. 

 The northern frog 

 {Rana septentrionalis), 

 which is the least 

 familiar one of my 

 : group, is distin- 

 guished for its dis- 

 agreeable odor. It 

 has a somewhat broad, 

 stout body, a narrow 

 head, and a rough but 

 not tuberculated skin. The color above is light 

 oli\e, covered on the lower half of the back with 

 lin-ge, nearly circular hlotches of brown. The legs 

 have a few blotches, but no bands. Beneath, the 

 color is a uniform dull whitish yellow. Compared 

 with Rana clamata* the species next described, this 



Northern Frog 

 (Rana septeidrionalis).
