Cliona celata Grant. [Chart 1 1 .] 



Desor, 1848, p. 68 (Spongia sulphured). Verrill 

 and Smith, 1873, p. 744, 421, etc. (Cliona 

 sulphured). 



Abundant and of pretty general distribution 

 throughout Vineyard Sound and Buzzards 

 Bay. Dredged by the Survey in 2 to 19 fath- 

 oms, on every sort of bottom. Sometimes 

 taken in sufficient quantity to fill the dredge. 

 Regarding the life history of this species Ver- 

 rill writes: "The sponge commences as a bor- 

 ing species, on various dead shells, and as it 

 grows it penetrates the shells in every direc- 

 tion, forming irregular holes and galleries, 

 which continue to grow larger as more of the 

 substance of the shell is absorbed, until the 

 shells are reduced to a completely honey- 

 combed, brittle mass, or a mere skeleton; 

 finally the sponge begins to protrude from the 

 surface."
