"This little species is found in wet stations about meadows, &c., from Vancouver to the 
coast, where it is most abundant, under dr-ift 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."— C.

This large slug aboimds 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 continued droxight. 
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
