are short and stout, those of the male longer and thinner. The under 

 parts are greenish white. 



Structure: Hind legs short. 



Voice: Its call is like those of the more southern forms. 



Breeding: They breed from May to early June. The eggs are in an 

 irregular jelly mass attached to vegetation. The eggs are 1/20-1/16 

 inch (1.2-1.4 mm.). The tadpoles transform at about 5/16-1/2 inch 

 (7.5-13 mm.). 



Notes: Aug. 31, 1930. Pembina, N. D., Red River of the North. 

 Along the shore is a mud flat baked and broken into squares. The 

 cracks are deep and fairly wide. We walked along the shore, more or 

 less abreast, Bert in the vegetation and I on the flats. I beat the 

 bordering vegetation with a cane. . . . Suddenly my eye espied a 

 small frog sitting at the edge of one of the clumps. As I looked, it 

 jumped into a crevice. To my surprise it was a Pseudacris septen- 

 trionalis. We have been looking for suitable places for the search of 

 this species at this dry period. Soon after, I saw a second clinging to 

 the edge of another crevice. As we came close, it cocked its head on one 

 side. A little later, a third appeared clinging to and crawling up the 

 close-grown grassy edge bordering the mud flats. All three are fe- 

 males. In captivky they leap 2-8 inches. Description of a female 

 from Pembina, N. D., Aug. 30, 1930: 



The color of top of head, top of arms and legs and back between 

 the three dorsal stripes is drab. The color between outer dorsal stripe 

 and lateral band is a smoke gray or pale drab gray. The band extend- 

 ing from snout through eye, over tympanum to near groin is olive 

 brown or brownish olive. This color is solid to the arm insertion then 

 goes over a pebbly surface, the interstices of which are smoke gray 

 or pale drab gray like the color above the band. The median and two 

 latero-dorsal stripes are buffy brown outlined with dotted lines of 

 olive brown. On top of head are a few specks of olive brown. The 

 femur and tibia also have spots of olive brown, and on front of tibia 

 and rear of foot and tarsus are half bars of the same color. On the 

 upper jaw there is a prominent line of olive buff or chartreuse yellow 

 bordered below, broadly on upper J aw and narrowly on lower jaw, 

 by a finely punctate band which appears buffy olive or drab. Under 

 surfaces are pale dull green-yellow, except for under side of hind legs 

 which is light grayish vinaceous. All five stripes are continuous. The 

 eye is olive brown except for the upper rim of pupil which is clear 

 yellow green. The iris is dotted all over with clear yellow green and 

 mars orange spots. The front, back, and lower margin of pupil is a 

 succession of clear yellow-green dots. The lower margin of pupil 

 rim is prominently interrupted below.
