This species was found by the writer, living in considerable num- 
bers, and of all ages, among the docks at Newport, R. I., July, 18S0. 
It occurred among decaying sea-weeds thrown up at high-water 
mark, both among the vegetable matter and on the under side of 
stones. 
Common on the coasts of Europe in similar localities. Perhaps in- 
troduced on this coast by shipping, but it may have been hitherto 
overlooked. It was associated with Assiminea Grayana and Alexia 
myosotis.
