 wigi, Wass., is no Condylactis. It has, so far as one can 

 tell, good acrorhagi and a weakish circnniscrib(;d-diffus(; 

 sphincter. If, as stated, it has no verrucae it should go to 

 Anemonia. If it has, to Bunodactis. C . par vicor nis, 

 Kwiet., does not seem to be a very typical Condylactis, 

 possibly that also is a Parantheopsis or Bunodactis. 



Parantheopsis, McM., 1904, p. 233. 

 See note under Condylactis. 



Actiniidae with vernicose body, the verrucae usually above ; they 

 are in vertical rows, ending, at least some of them, in acrorhagi (which 

 are not necessarily nematocyst batteries) ; foreign bodies sometimes 

 adhere to the verrucae. No sphincter or only a trace. All or a good 

 many of the mesenteries perfect, and all may be fertile save directives. 

 Good retractors. Tentacular longitudinal muscle of the simple ten- 

 tacles ectodermal. Tentacles and mesenteries may be hexamerous or 

 octamerous.

Actiniidae. A large genus of forms which are some of them easily 

 retractile, others of more lax habit and only retractile with diffi- 

 culty if at all. The body has regular vertical rows of verrucae, which 

 are sometimes graded in length, and in size of the individual verrucae, 

 according to the cycles of mesenteries they are connected with, and 

 this may be accompanied by colour distinctions between the verrucae. 

 Foreign bodies are often attached to the verrucae, wliich may also be 

 somewhat lobed, distally. Acrorhagi are usually developed in comiexion 

 with the upper ends of at least some of the rows ; but they may be there 

 or not even in one and the same species. They may be simple, small 

 or large, or decidedly compound. Sphincter variable, never very
