specific character. A small number of the specimens also 
show an increased number of body scale-rows. 
In the region of Puget Sound snakes of the vagrans 
type, 2 majority of which have two preoculars, are again 
encountered. We can see no reason for not including them 
here. It seems best to include here also the snakes from 
Del Norte County, California, and from Josephine and 
Coos Counties, Oregon, although the number of specimens 
from these localities is so small as to leave one in doubt as 
to the usual number of preoculars, and the coloration 1s 
more like that of T. 0. couchii. 
Perhaps nowhere else in the world are snakes so abund- 
ant as formerly near Klamath Falls. We counted 180 on 
a small rock about a yard in diameter in Link River, and, 
at another point on the same river, caught 14 with one grab 
with both hands. They feed upon small fish and toads. 
Most of these snakes are of this subspecies, but a few are 
Thamnophis sirtalis infernalis.
