" I received the largest specimen that I have seen of 

 this sponge, among others, from the Eev. A. M. 

 Norman, who stated that he received it from Mr. D. 

 Robertson, who found it under stones at Isle of Cum- 

 brae. It was an inch and three quarters long, nearly 

 an inch in width, and an eighth of an iach in thickness ; 

 it had thirteen oscula at nearly equal distances from 

 each other, and in its general aspect might have been 

 very readily mistaken for a young specimen of Ophlita- 

 spongia seriata when examined in the dried state."
