West Indies. This curious form has a slender whip-like corallium 

 more than nine feet in length.

A palmated Coral, which diifers from D. violacea in its bright 

 red tint, and the more compressed, broader, form of its stem and 

 branches ; their shelving edges giving the species " a rather 

 sword-like appearance." The much smaller cells, and narrower 

 lateral cell grooves also distinguish it.

This is a free Zoantharian allied, we think, to Peacliia of 

 Grosse. It was first found " adhering singly to the lower surface 

 of the disc in Olindias (nov. gen. JSucopidarum) , and afterwards 

 in plenty upon Ckrysaora, in which it dwells on the arms, in the 

 sexual cavities, and in the stomach and its sacs." None of the 

 specimens contained ova or spermatozoa. Rows of minute orifices, 

 leading into the grand cavity, were distinctly seen to radiate 

 from the hinder end of the body.

M. Valenciennes here reviews some of the species of Madre- 

 2?ora. The American forms of this genus, though sufficiently 

 distinct, he considers analogous with those found under corres- 

 ponding latitudes in the Eastern hemisphere.

 Echinodermata, new to Britain. (With Figs.). Ann. N. H.

The Zoophyte here described is Campanularia fastigiata, a 

 minute parasitic species allied to C. syringa, from which it chiefly 

 differs in the curious form of the lid closing the orifice of its 

 hydrotheca, or polype-cell. This, " when closed, slopes down on 

 each side like the roof of a house, the two opposite angles form- 

 ing the gables. When the operculum is fully open, the folds 

 disappear, and the edges unite into a continuous rim round the 

 top of the cell."

The structure of this species (== Lucernaria cyathiformis) is 

 detailed, and compared with that of a gymnophthalmatous Me- 

 dusid. The author does not fully estimate the closer affinity of 

 the Lucemariadce to the SteganophtJialmata.
