GENERA OF THE ALCYONAEIA STOLONIFEEA. 333 



Anthelia glauca, Savigny, = Clavularia glauca. 



Anthelia strumosa, Dana (3), = Clavularia strumosa. 



Anthelia purpurascens, Dana. (2), = Clavularia purpurascens. 

 Anthelia desjardiniana, Teinpletou,= Clavularia desjcrdiniana. 

 Anthelia capensis, Studer (28), = Clavularia capensis. 

 Anthelia filippii,Ko]liker {20), = Clavularia filippii. 



The name Gijmnosarca was given by Saville Kent (13) to a form that exhibits 

 numerous creeping stolon-like thick expansions, which anastomose and give rise to 

 free cylindrical stolons on which the polypes are found. It may be that Gijmnosarca 

 should more correctly be placed with Telesto among the Alcyonida, but the deter- 

 mination of this point must rest upon some future microscopic examination of the 

 "free cylindrical stolons." If they are really « stolons " (that is to say, if they are not 

 mainly composed of the fused body-walls of the polypes), there is no reason for 

 separating this form from the genus Clavularia. Whatever view we take, Gymnosarca 

 as a separate genus must disappear from the ClavulariidEe. 



The genus Cornulariella was described by Verrill (31) in 1874 in a footnote to a list 

 of specimens caught in a dredging-expedition on the coast of New England. 



The chief point of importance in this form is the presence of large fusiform spicules 

 with sharp conical projections, which thicken and stiffen the walls of the polype-bodies. 

 The actual size of these spicules is not given. 



It seems to me to be a mistake to place a species in a separate genus on the character 

 of the spicules alone. The spicules vary enormously in size, in number, and in distri- 

 bution in the various species of Clavularia. Sometimes they are very large, as in 

 Clavularia viridis (Plate L. fig. 16), sometimes very small, as in C. garcim, and sometimes 

 altogether absent, as in one variety of G. australiensis, C. celebensis, &c. 



If there were any other distinctive character of this form, it might be well to consider 

 it a separate genus ; but it seems to me, from the very meagre description that is given 

 (without any figure), that it is nothing more than a species of Clavularia with large 

 and peculiar spicules. In what respects it is allied to " Gornularia and Telesto " we have 

 no information. 



It seems to me, then, that Cornulariella modesta should become Clavularia modesta. 



The name Cyathopodiuni was given by Verrill (33) to a species formerly described by 

 Dana as Aulojjora tenuis. (It is obvious that in Verrill's paper Allopora is a misprint 

 for Aulopora.) Verrill says, " It is, in fact, a Tubij)ora-Yike polyp with short cup-shaped 

 cells, connected by narrow calcareous stolons, which correspond to the transverse plates 

 of Tuhiporct, and from which the polyps spring." 



I must confess that I fail to see that we have any evidence for supposing that this 

 form is allied to TuUpora. We have no figure nor description of the polypes, and we 

 have no figure nor description of the microscopic appearance of the calcareous stolon.
