S. I. Smith — Crustaceans of the Atlantic Coast. 
posed of a short basal portion, a linear onter lamella about three 
times as long as the base, and a very slender and minute inner 
lamella. The appendages of the sixth segment show nothing to dis- 
tinguish them from the corresponding appendages in the species of 
Eupagurus. The telson is about as long as broad and its posterior 
margin is arcuate and only very slightly emarginate in the middle.

Of this remarkable species I have seen only a single specimen, re- 
ceived, after the first part of this paper was in type, from Mr. Daniel 
McEachern, schooner “Guy Cunningham,” Gloucester, Massachusetts. 
It was taken, probably upon a trawl line, in 250 fathoms, hard bot- 
tom, off the coast of Nova Scotia, nearly due south of Halifax, north 
latitude 42 ° 41 ', west longitude 63 ° 6 ', and was inhabiting a peculiar 
compound actinoid polvp, which had evidently first grown upon the 
spiral gasteropod shell inhabited by the crab, afterward extended far 
beyond the shell, which it has very nearly or quite absorbed, and 
continued its growth rudely in the form of the original shell ; very 
much as Epizoanthus Americanus forms spiral cases inhabited by 
Eupaguri.
