Abundant everywhere from between tideniarks^ 

 down to considerable depths. It is frequently 

 infested by the following parasites : a Bopyrus in 

 the branchial chamber, Phryxus paguri and Pelto- 

 gaster paguri on the abdomen. A specimen taken in 

 Kilbrannan Sound, 75-80 fathoms, mud, had three 

 of the last named attached to it. The shells 

 tenanted by this species, when living between 

 tidemarks or in shallow water, are frequently 

 covered by Hydractinia echinata, a hydroid which 

 appears to show a marked preference for this 

 hermit-crab, though we have also taken it rarely 

 along with E. pubescens.

Common almost everywhere, from low water 

 down to 20 fathoms. In the Firth of Clyde it is- 

 always found associated with the anemone, Adamsia 

 palliata. Individuals frightened out of their original 

 shells in the hurry and commotion of the dredge
