Specimens examined* 



*In the column giving the miiuber of specimens, E indicates that the carcinoecia were formed of a 

 species of Epizoanthus distinct from either E. Americanus or E. paguriphilus, and u that the carcinoecia 

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

 in TJrticina, three in naked gastropod shells, and the others without carciuoBcia. 



As the above table shows, the Albatross dredgings have verygreatly 

 extended the bathymetrical range of this species. It had previously 

 been taken in 250 to 640 fathoms. This increased range in depth is ap- 

 parently accompanied by a change in the kind of carcinoecia inhabited. 

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

 carcinoecia of Epizoanthus paguriphilus Yerrill, while the deep-water 

 specimens were either in a very different species of Epizoanthus^ in 

 naked gastropod shells, or in an actinian closely resembling, if not 

 identical with, TJrticina consors Yerrill, which often serves for the car- 

 cincBcium of the next species.
