mens vary from 50 to 68, the average being 58. On the 
tail they vary from 14 to 20, and average 16.5. 
Distribution —Utah specimens of this subspecies are at 
hand from Weber (Ogden), Salt Lake (Fort Douglas), 
Wasatch (Wasatch Mountains), Grand (Thompson), Mill- 
ard (Kanosh), and Iron (Rush Lake), counties. Gopher 
Snakes have also been recorded from Utah (Provo), Millard 
(seven miles south of Kanosh, Fillmore), Beaver (Beaver), 
Iron (Rush Lake) and Washington (Beaverdam Mountains, 
Rockville), counties, Utah. Those from southwestern 
Utah may perhaps be P. c. deserticola. 
Three snakes from Boise, Ada County, and Blue Lakes, 
Twin Falls County, Idaho, and one from Wallula, Walla 
Walla County, Washington, may belong here rather than 
with P. catenifer deserticola, but their final disposition must 
await additional material. They have 29 and 31 scale- 
rows and one or two preoculars (50% each), and 
gastrosteges from 231 to 244. Dr. Stejneger has recorded 
specimens of Pituophis from Big Butte and Arco, Butte 
County, Idaho. A gopher-snake, in the National Museum, 
collected at Indian Valley, Adams County, may belong here, 
and, one from Bear Lake, Bear Lake County, doubtless is 
this subspecies. 
Habits —Mr. Herbert J. Pack has published the follow- 
ing notes on the habits of this snake: 
“In the summer of 1913, when the circumstance 
occurred, field mice were very numerous in an alfalfa field, 
where Mr. Merrill was working. A part of the communica- 
tion follows: 
“There were some young boys working with me and one 
of them ran on to a large Blow Snake with its head and 
about two-thirds of its body under a pile of hay. This boy
