Specimens examined.^ 



*In the column giving the number of specimen.s, E indicates that the carcinoecia were formed of a 

 epecie.s of Epizoanthus distinct from either E. Americanus or E. pagitriphihts, and u that the carcincacia 

 were a species JJrticina. Of the twelve specimens from Station 2037, four were in the Epizoanthus, two 

 in Urtidna, three in naked gastropod shells, and the others without carcinoecia. 



As the above table shows, the Albatross dredgings have very greatly 

 extended the bathymetrical range of this species. It had previously 

 been taken in 250 to G40 fathoms. This increased range iu depth is ap- 

 parently accomi)auied by a change iu the kind of carcinoecia inhabited. 

 All the earlier specimens, over four hundred iu number, were found in 

 carcinoecia of Epizoanthus pagtiriphilns Verrill, while the deep-water 

 specimens were either in a very diflerent species of Epizoanthus, in 

 naked ga8troi)od shells, or in an actinian closely resembling, if not 

 identical with, JJrticina consors Verrill, which often serves for the car- 

 cinoecium of the next species.
