A LIST OF THE AMPHIBIANS AND REPTILES OF 



UTAH, WITH NOTES ON THE SPECIES IN 



THE COLLECTION OF THE 



ACADEMY. 



By John Van Denburgh, 

 Curator of the Department of Herpetology, 



and Joseph R. Slevin, 

 Assistant Curator of the Department of Herpetology. 



The reptiles and amphibians of Utah have been but little 

 known. Stansbury's and Wheeler's Surveys, the report on 

 the Death Valley Expedition, Yarrow's Catalogue, and a few 

 notes by Cope, Dickerson, and Van Denburgh include about 

 all that has been published on the subject. Some of the 

 records, particularly those of Yarrow, are open to question. 

 As in the List of Amphibians and Reptiles of Arizona, pub- 

 lished in 1913, it has been our aim to exclude from this list 

 all species not definitely known to live within the state. Where 

 we have been in doubt as to the authenticity of a record the 

 species has been omitted. 



Our Utah collections are chiefly the result of the efforts of 

 Mr. Slevin during the spring and summer of 1913, but a large 

 number of specimens was secured for us by Chaplain Joseph 

 Clemens, U. S. A., mainly in the vicinity of Fort Douglas. To 

 him our thanks are due. 



The following list includes. 36 species. Those which the 

 Academy has not yet secured from within the borders of Utah
