 dean Sponges, &c.,' Ann. Nat. Hist., ser. 4, iii, p. 299. 



" Among some fresh specimens of British sponges 

 recently received from my friend, the Rev. A. M. Nor- 

 man, were the two valves of a Pecten varius, one of 

 which was entirely covered, and the other very nearly 

 so, by this sponge, which did not exceed half an inch 

 in thickness at any part of it. Under these circum- 

 stances the external characters were very different 

 from those of the two specimens previously described, 

 their surfaces being smooth and even, but having the 

 thin, white, leather-like aspect of the earlier speci- 

 mens. Anatomically, the structures were in perfect 

 accordance with the type specimen. This sponge 

 was dredged by Mr. Norman in Roundstone Bay, 

 Ireland."
