DESCRIPTION OF ANEW RATTLESNAKE (CROTALUS 

 PRICEI) FROM ARIZONA. 



BY JOHN VAN DENBURGH, 

 Curator of the Department of Herpetology. 



In a collection of reptiles made by Mr. W. W. Price 

 for the Leland Stanford Junior University is a new spe- 

 cies of rattlesnake which I take pleasure in naming for 

 its energetic collector. 



Crotalus pricei n. sp. 



Diagnosis. — Small; internasal and prefrontal plates 

 large; anterior nasal in contact with rostral; supraocular 

 normal; nine supralabials ; 153-159 gastrosteges ; two 

 rows of small dorsal spots; belly dark slate. 



Ty^e. — Leland Stanford Junior University Museum 

 No. 1702, Huachuca Mts., Arizona; W. W. Price; July 

 or August, 1893. 



Hahitat. — Southeastern Arizona, probably in mountains 

 only. 



Description. — Small; head subtriangular; rostral nearl}^ 

 as broad as high ; two nasal, one loreal, and two preocu- 

 lar plates; two internasals; four prefontals; one to three 

 rows of scales between supraoculars; nine supralabials ; 

 nine infralabials, first pair in contact on the median line; 

 one row of scales between labials and orbit; scales in 

 twenty-one rows, parts of the lower two smooth; gastro- 

 steges 153 to 159; urosteges 21 to 27, the first and from 

 two to nine of the posterior ones usually divided; rattle 

 very slender and delicate. 



The general ground color is olive gray so thickly cov- 

 ered with minute brown dots as to give the animal a 

 decidedly brownish hue. A narrow dark brown band of 

 uniform width runs back and down from the eye just 

 touching the upper angles of the eighth and ninth labials
