Voz. IIT] VAN DENBURGH AND SLEVIN—ARIZONAN REPTILES 425 
caught in Ramsey Canyon, Huachuca Mts., July 29, 1912. 
It is No. 34757, and has scales in 15 rows, gastrosteges 157, 
anal divided, urosteges 58, superlabials 7—7, infralabials 7-6, 
preoculars 1-1, postoculars 2-2, temporals 1-++1, posterior 
genials shorter. The white collar crosses the posterior por- 
tion of the parietals and about two rows of scales on the 
neck. It is about as wide as the length of three scales, and 
is bordered behind by a dark band about the width of one 
scale row, and is similarly edged with dark anteriorly. The 
first infralabials just meet on the midline. The color below 
is coral-red. 
This species may be distinguished from T. nigriceps by 
the position of the light collar, the larger number of gastro- 
steges, and the meeting of the first infralabials. 
The specimen collected in the Huachucas by Mr. Price, 
August 20, 1893, originally recorded by me (Proc. Cal. Acad. 
Sci. (2), VI, 1896, p. 346), as T. coronata has only 148 
gastrosteges, while Dr. Stejneger’s type has 152.
