25. CHARINA 643 
Description—Top of head very slightly rounded, 
covered with plates which vary in size, shape and relations. 
Usually a large frontal, bordered on each side by two supra- 
oculars and behind by a broad crescent-shaped plate. Usually 
three pairs of plates, with or without one or more small 
azygous plates, between frontal and rostral. Loreals vari- 
able. Labial plates sometimes entering orbital ring, anterior 
labials very high. Scales on body smooth, imbricate, about 
as wide as long, and arranged in 41 (or perhaps 43) longi- 
tudinal rows, lowest row in each side being formed of larger 
scales. Gastrosteges rather narrow and ranging in number 
from 202 to 210. Urosteges in one series of from 33 to 39. 
Anal spurs small. Tail very short and nearly as blunt as 
head.

Remarks.—This subspecies differs from C. 4. botte in 
the number of scale-rows. These are 41 in eight specimens 
from Utah and three from Idaho. One specimen from Cody, 
Bighorn County, Wyoming, and another from Chico, Park 
County, Montana probably should be referred to this sub- 
species, although each has 43 rows of scales. 
Distribution—In Utah, this boa has been found in 
Wasatch (Little Cottonwood and Provo canyons in the Wa- 
satch Mountains), Cache (12 miles up Logan Canyon), 
and Salt Lake (Fort Douglas) counties. 
In Idaho, it probably is this subspecies which has been 
collected at Blue Lake and in Hood’s Valley, Kootenai
