Creek (7800 feet), 1; head of Leonard Creek (8500 feet), 4; and 

 head of Big Creek (8000 feet), 2. The species was fairly common 

 in suitable environments at altitudes of 8000 feet or over. 



This toad may be found to approach or be referable to Biifo 

 boreas nelsoni (Stejneger, 1893, p. 220), the type locality of 

 which is Oasis Valley, Nevada. In the Pine Forest Range the 

 species is completely isolated geographically and so might be 

 expected to exhibit variation from typical boreas. 



Habits. — These little toads were not infrequently noted on 

 mountain meadows. Two individuals, probably a pair, were 

 found in an iris patch on a meadow at the head of Leonard 

 Creek. Two others were taken in short meadow grass between 

 some rocks at the margin of the same meadow. Near Duffer Peak 

 an individual was secured on the shore of a small lake, and on a 

 nearby meadow one was observed hopping along on the dry 

 ground among some green leafy plants a yard distant from a 

 spring. One was found near a high mountain lake in a steer 

 hoof -print which was filled with water, another being secured in 

 the lake itself. 



Bufo lentiginosus woodhousei Girard 

 Rocky Mountain Toad 



Distribution. — Taken at three points touched by the expedi- 

 tion: Quinn River Crossing (4100 feet), 13 specimens; Big Creek 

 Ranch (4350 feet), 9; and Leonard Creek (4300 feet), 1. As 

 would be implied by these figures, Bufo lentiginosus woodhousei 

 was the common toad of the flat, but did not range into the 

 mountains even along th'j streams. A single individual was 

 observed near the stream at Alder Creek Ranch. 



I have seen no record of the species from northern Nevada. 

 Dr. C. Hart Merriam has recorded it (in Stejneger, 1893, p. 221) 

 from several localities in the southern part of the state. 



Habits. — Toads were numerous along the streams at Big Creek 

 Ranch. Five were caught in one day. One strove to escape by 

 swimming to the bottom of the stream and remaining there 

 quietly for several minutes. As a rule, however, when the toads 

 are pursued, they leave the water and try to escape by rapid
