(Pitt), but without specimens they throw little light on the range 

 of the subspecies. 



General habits. The type specimen was caught in a trap set in a 

 shallow burrow where a pocket gopher had been caught the day 

 before, but in the loose soil of the mountain slope it was not always 

 possible to distinguish between the mole and the pocket-gopher 

 burrows. Both species apparently used the same tunnels. 



SCAPANUS ORARIUS ORARIUS TRUE] 

 COAST MOLE 



ticapanus orarius True, U. S. Natl. Mus. Proc. 1&: 53, 1896. 



Type. Collected at Shoalwater Bay, Pacific County, Wash., August 30, 1855, 

 by J. G. Cooper. 



General characters. Size medium, much smaller than in townsenMi; form 

 slenderer, with relatively as small or actually smaller and slenderer front and 

 hind feet, tail, snout, and feet almost naked; fur shorter and finer than in 

 townsen-dii and of almost the same shade of color, purplish black at the surface 

 and plumbeous underneath. Skulls strikingly different in size but very similar 

 in general characters. 



Measurements. Average of three adult males from Eureka, Humboldt County, 

 Calif.- Total length, 167 (163-175) mm; tail, 33.7 (31-35) ; foot, 20.7 (20-22). 

 Adult male from Puyallup, Wash. : 160 ; 36 ; 21. Weight 2 ounces. Adult female 

 from Puyallup, Wash. : 15.7 ; 37 ; 21. Weight 1 15/16 ounces. 



Distribution and habitat. Humid coast section of northwestern 

 California, western Oregon and Washington, entirely west of the 

 Cascades (fig. 82). The 

 range overlaps that of the 

 large Townsend's mole al- 

 most completely, and both 

 are taken on the same 

 ground, but the small form 

 is usually much less com- 

 mon than the large one. 



General habits. So far 

 as known the habits of the 

 coast mole seem not to 

 differ from those of other 

 moles of the genus Scap- 

 anus. Economically these 

 moles are of importance 

 mainly in the destruction 

 of ground-dwelling worms 

 and insect larvae. Their 

 small ridges and mounds are of little consequence 111 cultivated 

 ground, and their small size prevents any important fur value attach- 

 ing to their skins. 



SCAPANUS ORARIUS SCHEFFERI JACKSON 

 SCHEFFER'S MOLE 



Kcapawus orarius scJiefferi Jackson, North Amer. Fauna No. 38, p. 63, 1915. 



Type collected at Walla Walla, Wash., August 8, 1914, by Theo. H. Scheffer. 



General characters. Slightly larger and with heavier feet and claws than 

 in typical orarius; skull relatively shorter and wider; colors paler, more 



7209'
