82 BEITISH SPONGIAD^. 



ham, and sent to me for examination I found a 

 specimen of H. sanguineus partially covering a small 

 mass of Ealichondria panicea. The combined mass 

 was about two inches in length and rather exceeding 

 half an inch in thickness. This sponge occurs in many- 

 localities on the coasts of Scotland and Ireland, but this 

 is the first time I believe that it has been taken so far 

 southward as the Channel Islands."

Habitat. — Shetland, 1858; Westport and Round- 

 stone Bay, Ireland, 1874 (N.). 



" I received from the Rev. Mr. Norman two speci- 

 mens of this species . One from Roundstone Bay, three 

 inches in length, one and a half in breadth, and about 

 half an inch in thickness. This specimen agrees in 

 all its characters with the type. The second speci- 

 men was from "Westport Bay. It was an irregularly 

 oval mass, the greatest length not exceeding eight 

 lines. Anatomically it was identical with the type 

 specimen and the larger one described above, but in 

 form and surface it difEered widely from both of them, 

 there being scarcely an indication of the remark- 

 able mammiform organs that are so characteristic 

 of the mature specimens, and the colour instead of 

 being nut-brown was nearly cream-white."
