466 Happon—The Actiniaria of Torres Straits. 
Corallimorphus of Moseley (1877), with the following definition :—‘‘ Hexamerous 
Actiniee with a double corona of tentacles, a corona of marginal principal tentacles, 
and a corona of intermediate accessory tentacles. Septa [mesenteries] slightly 
differentiated, all furnished with reproductive organs. Muscular system weak in 
all parts of the body. No circular muscle.” He also draws attention to “an 
affinity between the Corallimorphide and Allman’s genus, Corynactis.” In the 
supplement to his ‘‘ Challenger” Report (1888), Hertwig definitely places the genus 
Corynactis in his new family. In the meantime, Andres (1884, p 265) had placed 
Corynactis, Corallimorphus, and Capnea in a sub-family Corynactidz, which, 
together with seven other sub-families, made up his family Stichodactyline. 
Gosse (1860, p. 278) had already allied Capnea, Aureliania, and Corynactis in 
a new family, the Capneade. Ido not propose to say anything about Capnea, 
and Aureliania, as nothing is known of their anatomy. 
CORALLIMORPHUS, Moseley. 
Corallimorphide with the marginal and intermediate tentacles knobbed; 
marginal tentacles uniserial, varying in size according to position (6 +6 + 12 +24); 
accessory tentacles in hexamerous cycles, never more than one in a given radius. 
Mesenteries all fertile. Muscular system weak in all parts of the body; no sphine- 
ter muscle ; feeble ectodermal muscle in body-wall.

CORYNACTIS, Allman. 
Corallimorphide with the marginal tentacles alternately larger and smaller 
(23 or 82, or 56); aecessory tentacles in tetramerous cycles, more than one in a 
single radius. LKctodermal muscle layer in body-wall; a feeble endodermal 
sphincter present.
