This was found in July, 1880, by tle writer, living among decay- 
ing sea-weeds, at high-water mark, between the docks at Newport, 
R. I., where it was common, associated with Truncatella and Alexia. 
Common in similar localities on the British and other European 
coasts.

This species was found by the writer, living in considerable num- 
bers, and of all ages, among the docks at Newport, R. L, July, 1880. 
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.
