12. CARYOPHYLLIA EPHYALA (Alcock). 



C. epkyala, Alcock, Investigator, Deep-sea Madreporaria, p. 13, 

 pi. I., figs. 4, 4a (1898). 



C. scyllaeoniorpha, Alcock, idem., pi. I., figs 3, 3a. 



C. scobinosa, Alcock, Siboga, Deep-sea Madreporaria, p. 8, pi. I., 

 figs. 2, 2a (1902). 



I have referred five specimens to this species though they ai^e 

 to some extent divergent from it, approaching both to C. 

 scobinosa and also to C. scyllaeomorpha. Their variation may 

 best be seen in the accompanying table : — 



Nos. 2, 4, and i — the latter an obvious variation from hexa- 

 symmetry — approach closely to C. ephyala in shape, but are 

 rather more constricted at the base than the type of that 

 species. All further agree with that species in the general 

 characters of costae, septa, pali, and columella, but all parts in 

 the Cape specimens are more delicate and thinner. 



Considering the whole question, if Duncan's account of varia- 

 tion in C. clavus {Trans. Zoo. Soc, VIII., p. 310) and my account 

 in Flabellum rubrum (Marine Investigations in South Africa, 

 vol. II., p. \\J et seq) be correct, I cannot consider that C. 

 scyllaeomorpha and C. scobinosa are beyond the limits of varia- 

 tion of C. ephyala. The same remark applies to several other 

 species of the same and other authors, but my specimens do not 

 approach any of them closely enough for me to deal with them 

 here.
