A common species found under stones at low-water mark in bays, &c. It looks very much 

 like the pill-bug or saw-bug of the land, (Oiiiscus,) and like it rolls itself into a ball when 

 disturbed. 



Numerous other Crustacea are found on the coast of the Territory, but none of them fell 

 under my observation. For a complete enumeration of them, with synonymy and description 

 of new species, the reader is referred to Stimpson's article in Journ. Bost. Acad., vol. VI.
