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, a 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 is 

 more like that of T. o. 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 inf emails.
