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

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.”
