Family SCAPHIOPODIDJE. 

 Scaphiopus hamniondii Baird. 



The four specimens representing various sizes and ages from the same 

 locality will ultimately be of great help iu better understanding the 

 status of this species. The few specimens now in the collections from 

 a number of localities scattered over a very wide area, and often in a 

 bad state of preservation, form a very unsatisfactory material upon 

 which to base a rational discussion of the question.

Family Hylidje. 



Hyla regilla B. & G. 



We have been so accustomed to regard this species as chiefly 'Pa- 

 cific 7 in its distribution that it was rather a surprise to receive such 

 an enormous number of specimens from so many localities in the desert 

 regions visited by the expedition. Our knowledge as to the geographi- 

 cal distribution of this species has consequently been considerably ex- 

 tended, and there can be no doubt that the material gathered will be of 

 extreme importance whenever it shall be possible to work up in detail 

 the unequaled series in the National Museum. As my assistant, Mr. 

 Frederick C. Test, has been engaged for some time upon this work, I 

 shall refrain from further remarks in order not to forestall any of his 

 conclusions. 



[On the west or coastal slope of the Great Divide in California, tree 

 toads of this species were found in Kern Valley, Walker Basin, and at 

 Old Fort Tejon in the Canada de las Uvas. On the east or Great Basin 

 side of the divide they were tolerably common about the spring in Sur- 

 prise Canon in the Panamint Mountains, at Hot Springs in Panamint 

 Valley, at Saratoga Spring at the south end of Death Valley, and at 

 Besting Springs. In Nevada they were found in Ash Meadows^ Oasis, 

 Pahruurp, and Vegas valleys. — C. H. M.]
