20 PROCEEDINGS OF THE ACADEMY OP [1883. 



this toad was as large as the average Bufo marinus of Brazil, 

 and a specimen seen at Warner's Lake was but little smaller. 



Hyla regilla B. and G. 



Abundant at Silver Lake, at Warner's Lake, Goose Lake and 

 at Fort Bidwell, twenty miles east of Goose Lake, in California, 

 I found numbers of what I suppose to be a variety of this species. 

 It is little over half as large in linear dimensions, and the skin is 

 more distinctly tubercular above. Some of those from Goose 

 Lake are more spotted ; those from Fort Bidwell are nearly 

 uniform golden-yellow and green. This species lives in swamps 

 and on the edge of water, representing in this region the Acris 

 and Ghorojyhilus of the east. 



Kana pretiosa Bd. and Gird. 



This is the characteristic Rana of the northwestern interior, 

 being accompanied hy Bufo columbiensis and Bascanium vetustum. 

 In life the posterior part of the abdomen, with the inferior faces of 

 the thighs, are of a bright salmon-red. I obtained it the entire 

 length of the valley of the Warner Lakes, but not at Fort Bidwell. 

 I have found it to range as far as the eastern foot of the Rocky 

 Mountains in Montana ;^ and the specimens assigned by me- to 

 Rana septentrionalis, from the Yellowstone Basin, may be the 

 variety described above from Salt Lake City. I do not now have 

 them before me for decision. Specimens of this species are in 

 the National Museum, from Puget's Sound (Dr. Kennerly. No. 

 5915 a) and from " Camp Moryie " (Dr. Kennerly, No. 5973). The 

 first-named specimens are accompanied by the R. temporaria 

 aurora. It habits are aquatic. 



Phrynosoma douglassi Bell. Yar. 



On the elevated land which represents the Sierra Nevada Range, 

 between Warner's Lake and Goose Lake, in the basaltic region, 

 near the former, I found a peculiar variety of this species. The 

 horns are even more rudimental than in the usual form, but are 

 all represented. The prominent scales of the back are smaller 

 and less prominent. In some of the specirpens the head is shorter 

 relatively to the body, The color is an ironi'ust-brown, with 

 darker lateral spots, each with a small posterior yellow border.
