Ox a New Species op Distichopoea. 



By the Eey. J. E. Tenison- Woods, F.G.S., F.L.S. 



The following- species of Bistichopora has not, I think, been 

 described, at least I can find no record of its description. It is 

 very common I should think in the Islands, as I have seen a 

 good man}- specimens of it at various times, amongst collections 

 of shells and curiosities from Solomon Islands, between Lat. 5° and 

 12° S. and Long. 154 and 163 E., and the Penrhyn Islands, Lat. 

 9° 12' S. 154° 35' W. Also from the Marshall Group. I cannot 

 however be sure of the locality in any case, as the information I 

 could procure was not only obtained second-hand, but also in 

 general, vague and indefinite. The species is particularly 

 interesting, as its habit is larger and stouter than D. coccinea, 

 Gray, which is our largest species from the Pacific. I have not 

 seen the descriptions of the species dredged by Pourtale in the 

 Atlantic. 



DlSTTCHOPOPA LIYTDA, 11. S. 



Corallum, in stout, solid tufts, three or four inches high, 

 flabellate or twisted, and gnarled like the branches of a tree, not 

 always spreading in the same plane, very solid and compact, 

 livid, tips of branches sometimes yellow or white, lateral furrows 

 and tips of smaller branches bright red or orange. Branches 

 almost cylindrical, stout, rugose, very finely vermiculate, many 

 projecting branchlets, the central stem often disproportionately 

 thicker than the branches and smooth. Lateralf urrows conspicuous ■
