947, 312 fathoms, three hundred and ninety-three specimens, nearly all adults 

 and many of them very large, were taken at one haul of the trawl. 



The carcincecia of all the specimens seen are formed by colonies of Epizoan- 

 thus payuriphilus Verrill, which at first invest spiral shells which are finally 

 absorbed by the basal ccenenchyma of the growing polyps.
