Text-Fic. 14. 
Arrangement and form of tentacles. A, Aureliania, sector of 
disc, with various sorts of tentacles, and two to each exocoel 
and endocoel. B (surface view) and c (side view), of a dendritic 
tentacle of Actinotryx. In c the stem is embedded in the 
mesogloea of the disc. pD is a sector of the disc of an Actiniine 
form with plain tentacles, one to each endocoel and exocoel. 
£, a radial group of dendritic tentacles and nematospheres from 
Thalassianthus. All this belongs to one endocoel. F, sector 
of disc of Antheopsis for contrast with p, showing some of the 
tentacles in endocoelic radial rows; here some of the tentacles 
have been cut off for the sake of clearness. G, knobbed tentacle 
of Corallimorphus. 4, sector of disc of Phymanthus, 
showing marginal pinnate tentacles in alternating cycles and 
small dise-tentacles in radiating rows. The pinnate character is 
not very clear, as the specimen was distorted. K, arm or disc- 
lobe of Megalactis, bearing tentacles. (After Saville-Kent. 
See acknowledgement on p. 496.) In 4, D, F, exocoels are white, 
endocoels shaded.
