486 Wisconsin Academy of Sciences^ Arts^ and Letters, 
all in Iron county. A small stream fed into Lake 33^ and it was 
in the deeper parts of this—10 to 12 inches^—that all were seen. 
The one collected had eaten four beetles {Dytiscus sp.) as well as 
several isopods. Reported from Houghton county (1). 
American Toad. Bufo americanus Le Conte. 
Found quite commonly in both counties, though more were 
seen in Houghton than in Iron—probably because the localities 
visited were better suited to them. Of local distribution only, 
apparently being limited to the more open fields and underbrush, 
as none were found in the dense woods. 
Tree Frog. Hyla versicolor Le Conte, 
Several were seen around Kenton, both on the houses and on 
the stubs of trees not in the clearings. In the Lake 33 region, a 
single individual was found, perched on one of the ropes of the 
tent. This fellow had eaten nothing but flies, two species of 
Mnsca and one SyrpJius being noted. 
Spring Peeper. Hyla pickeringii Holbrook. 
Fairly common in Iron county, where they were found along 
the shores of the smaller lakes, provided that a sufficient quantity 
of vegetation was present. Two were examined for food, and 
the stomachs were found to contain the remains of small-sized 
amphipods (possibly Hylella), and some small worms. In 
Houghton county, a single specimen was collected in the Kenton 
river riding on top of a small piece of wood. 
Swamp Tree Frog. CihoropMlus nigritus (Le Conte). 
Three individuals of this species were collected in Iron county, 
and none were found in Houghton. These three were found 
within twenty-five feet of each other, in the same stream which 
Diemictylus viridescens was taken. All the stomachs were 
empty. 
Leopard Frog. Rana pipiens SJireher. 
Very common in both of the counties. Found along the shores 
o-^' the lakes or streams nearly any place where there are reeds 
or rushes for their protection, and often in the cut-over fields, 
especially if they are at all moist.
