 lipore, and rock. D. larraburei was encountered also in shore collecting 

 and even in Pocillopora coral.

 records a specimen taken at Long Beach by H. N. Lowe, in territory 

 familiar to the writer, as well as the Weymouth specimen from Monterey 

 Bay. This dromid crab slips into and out of his sponge "house" with great 

 facility.
