 tipped with orange. 



Only eleven adult B. horeas w^ere collected, although the 

 large number of tadpoles and young individuals observed in- 

 dicate that the species is abundant both in the Humboldt Valley 

 and James Canyon. The tadpoles were so numerous in the 

 pools that the water was frequently black with them, and in 

 late July the trails in James Canyon were fairly covered with 

 tiny, recently transformed toads. 



Adults were first observed along the irrigation ditches near 

 Annie Creek, on July i6, and several of the females taken 

 ■on this date contain eggs. They were found in the dense grass 

 along the edge of the ditches, and when disturbed slipped into 

 the water, where they floated, making no further efifort to 

 escape. As soon as the water was turned back to the creek 

 the toads disappeared and were not seen again until August 9, 

 when the ditches were again filled. 



In habits our toads correspond closely to Miss Dickerson's 

 description of B. halopJiilus (The Frog Book, 114). The 

 adults were large and tame, they usually walked instead of 

 hopped, and when confined in a bag they scolded much like 

 B. americanns. 



The stomach contents consist of ants and beetle fragments.

A large series of this species was secured in the upper part 

 of James Canyon and on the Carlin Peaks. 



The sixty-one specimens collected show little variation from 

 the descriptions of Test (Proc. U. S. Nat. Mus., XXI, 1898, 

 477-492) and Dickerson (The Frog Book, 134-135). The 

 adults were light gray in color, with brownish gray markings 

 on the back. They vary in size from 1^/2 to 2 inches; the
