The annelids are not very generally addicted to commensal or parasitic habits. Many Polynoids, however, live on the houses or bodies of their neighbors and a species of Polydora has been described which tunnels for itself a house in snail shells inhabited by hermit crabs. This latter host has been known for several years to harbor a western European species, Nereis fucata, Sav. although it has only recently been shown that this commensal mode of life is correlated with structural modifications in the body of the worm.
The purpose of this paper is to give a comparative description, of two almost similar commensal forms from the Pacific coast. Although it has been necessary to make a new species of the Nereid, and although the hermit crab is regarded as a modification of the type form, the general resembance of the commensalists of the Old World to their respective representatives in the New, gives evidence of a common origin of this commensal habit.
