DESCRIPTION OF A NEW SUBSPECIES OF BOA 

 (CHARINA BOTT^ UTAHENSIS) FROM UTAH 



BY 



JOHN VAN DENBURGH 

 Curator, Department of Herpetology 



The existence of boas of the genus Charina in Utah was re- 

 corded by Mr. Slevin and myself in 1915. These snakes then 

 were regarded as identical with the snakes of the Pacific Coast. 

 Further study shows that, while the boas of these two areas 

 are alike in almost every respect, they differ in the number of 

 scale-rows. The specimens from Utah all have 41 rows of 

 scales, while this number is found very rarely in the snakes 

 from the Pacific states. However, since an occasional speci- 

 men from the latter region has only 41 rows, it seems best to de- 

 scribe the Utah snakes as a subspecies. 



Charina bottae utahensis, new subspecies

 in only 41 rows. 



Type. — Cal. Acad. Sci. No. 38421, adult female, collected by

 tains, Wasatch County, Utah, June 28, 1913,
