&quot;This little species is found in wet stations about meadows, &c., from Vancouver to the 

 coast, where it is most abundant, under drift logs, &c., high up on the meadows, which are 

 occasionally overflowed by the tide. It is also rarely found under trees. I did not obtain any 



at Puget Sound.&quot; C.

This large slug abounds in the dense, damp spruce forests near the Pacific coast, and was not 

 observed by me in the dry region east of the Cascade mountains. It is to be found during 

 every month of the year in Washington Territory, being even more abundant in the rainy 

 winter than in warmer seasons; its activity being checked only by severe cold, while it cannot 

 bear continual drought. 



It not unfrequently drops from the trees, but whether it ascends to any great height I have 

 not observed. Though apparently offering a tempting meal to birds and other animals, I never 

 knew them to devour it. 



This slug grows to the length of six inches, but shrinks to a third of that size in alcohol. Its
