80 ^ ACCOUNT OF BRITISH SPONGES. 



Species, the palmated kind might be called dama- 

 cornis. Coast of Devon, rare. 



3. Palmata. Palmated, with finger-like divisions 



on the margin, and little prominent pores ir- 

 regularly disposed. 



Spongia palmata. Ellis, Zooph. p. 189. t. 58, f. 

 Gmel p. 



This, in some of its varieties, somew^hat ap- 

 proaches Spongia ociilata, is of a similar texture, 

 but not so soft when dry, and the pores more nu- 

 merous, and disposed all over the surface. Coas^ 

 of Devon, rare. 



4. Coaliia, Much branched in an irregular and 



distorted manner, rather compressed, and of 

 a brittle corky substance. 



Spongia coalita. Gmel. p, 3825. — Mull. Zoo}, 

 Dan. iii. t. 120. 



This species is much branched, and composed 

 of finely reticulated fibres, with seldom any larger 

 pores: the stalk is scarcely larger than the branches, 

 and both usually become sub-carinated at the sides, 

 on which part a few porous tubercles are some- 

 times observed : the branches are frequently hook- 

 ed, and turn in different directions, but preserve 

 a flattish form. Coast of Devon, rare. 



Muller is certainly mistaken in referring thi§ t^ 

 the octilata of Ellis.
