This hermit-crab generally lives in a portable house formed by a 

 particular species of Epizoanthus. The zoophytes and the hermit-crab 

 appear to begin as common tenants — inside and outside — of a small 

 gastropod shell which ultimately by the growth-pressure of its occupiers 

 becomes absorbed, so that the hermit-crab comes at last to lie in a spiral 

 cavity of the coenosarc — now of a gristly consistence — of the zoophyte-colony : 

 the life-partnership is a settled phase of an association which, in various 

 looser forms, is of very common occurrence between hermit-crabs and 

 zoophytes.

 This small species, which inhabits shells of Denialium, has the abdomen 

 fully extended in a straight line. It differs from P, pilostmanus in the following 

 characters : — 



The rostral bulge is hardly perceptible, and the greatest breadth of the 

 carapace is hardly two-thirds its length in the middle line.
