CLASSIFICATION OF ACTINIARIA 277 



DoFLEiNiA, Wass., 1908, p. 13. 



Actiniidae with smooth body. The only described form has large 

 tentacles rather like those of a Bolocera, and both these and the 

 disc are covered with papillae, plainly visible to the naked eye, and 

 which represent batteries of nematocysts. Longitudinal muscle of 

 tentacles ectodermal. Sphincter and retractors diffuse. 



Species : 



D. arm at a, Wass., 1908, p. 14. 



This is a genus not very clear in its exact relationships, but 

 it does not seem to fuse readily with any other, and the papillose 

 disc and tentacles are a distinct feature. 



IxALACTis, Haddon, 1898, p. 443. 



Actiniidae with the wall smooth below, with suckers above, and 

 a definite crenulated parapet. Disc flat when fully expanded, but often 

 thrown into lobes, and not fully retractile. Tentacles numerous, the 

 aboral side of each being smooth, the oral side flattened, and with 

 symmetrical lateral swellings, so that the whole looks not unlike a knotted 

 cruciferous seed-pod in some conditions. Sphincter moderately 

 developed, circumscribed. 



Species : 



I. simplex, H. and S., 1893, p. 123. (See Haddon, 1898, p. 443.) 



A very distinct genus. Probal)ly the form photographed by 

 Saville-Kent as Condylactis, sp. It is a possibility that 

 the genus is identical with Kagactis as represented by 

 Andres's figures of K. pulchra — at any rate they suggest it, 

 and it would be an interesting point to follow up. 



Glyphostylum, Koule, 1909, p. 14. 



Actiniidae. In the one form described the body is a long trumpet with 

 short stout tentacles. The tentacles are thicker on one face than the 

 other, and their longitudinal nuisculature is ectodermal and much 

 stronger on the thick side than the other. Smooth body-wall and no 

 sphincter. 



Species : 



G. calyx, Roule, 1909, p. 16. 



Koule (1909, p. 2) has set up a sub-family Glyphactininae 

 of the Antheidae (Actiniidae), to rank equal with two other 

 sub-families, the Bolocerinae and Actininae. His sub-family
