portion of Washington and Oregon lying between the Cascade Moun- 

 tains and coast range, and a sliort distance into California along the 

 coast. The most southerly specimen examined was from Crescent City, 

 Cal. Here the species appears to end, though it may go a little iarther 

 south. It shows no dis})osition to grade into H. californicu.Sj which 

 reaches up toward it. The character of the moles inhab'ting the area 

 between Crescent City and Cahto remains to be determined, but they 

 will probably prove to be S. caUjornints. 



On the seacoast of Oregon, from the Coquille IJivcr northward, on 

 the coast of Washington, the south shore of the Straits of Fuca, and 

 both sides of Paget Sound, we find another species, S. orarius, dark 

 colored, like S. toivnsendi, but very small. Tliis lives with S. ton-u.sendi 

 at Steilacooiu and probably at other ]>oints about Puget Sound. It 

 occurs also at Chiloweyuck and Sunuis, British Columbia. 



GEOGKAPHICAL DISTRIBUTION OF THE SPECIES OF SCAPANUS. 



There is a species, as we have said, living at Fort Walla Walla, as 

 evidenced by specimens in the National Museum collection obtained 

 by Major Bendire„ But whether it is to be associated with townsendi 

 or orarius is uncertain. The material at command consists only of 

 three A'oungish individuals in alcohol. The skull of one of these, 

 which exhibits characters of immaturity, is larger than adult orarius 

 from Sumas, but smaller than youngish townsendi. I am inclined to 

 regard it as an offshoot of orarivs, but when raore si^eciraens have 

 been collected along the Columbia Eiver eastward of the Sierra 



K'ross licatcbing indicates Scapanus orarius; heavy stippling, S. townsendi: light 

 stippling, S, calif ornicua ; and small circle iu Lower California, S. anthonyl.
