Genus Cucumaria I'lainville 1830. 

 56. Cucumaria capeusis Tiieel var. pavva, viir. u. 

 (PI. Vm., Fig. 74 ; textfig. 45). 

 Specimens examined : — 



Description : — Body subcylindrical with the anal portion 

 slightly curved upward or dorsad. In life, I observed five delicate 

 tentacle-like pedicels (or })apilLi3) around the anus. The 

 pedicels in the middle parts of the ventral trivium are somewhat 

 more pronounced than those in other jjarts, and give to the 

 parts a sole-like appearance as in Colochirtis. The pedicels in 

 front and back of this sole-like part are more slender. These 

 remind one of the small delicate papilla? described by Thi:el as 

 a second kind of pedicels in Cucumaria insolens, but I can not 

 find any such arrangement as described by that author for that 

 species. The trivium is well pronounced showing numerous 

 pedicels, while the dorsal bivium is more difiicult to make out 

 on account of the dark pigments in the entire dorsal region. 

 There are two rows of pedicels in each ambulaei'um. Tentacles 

 ten, of which the two ventral are considerably smaller than the 

 others and show scarcely any branches, liospiratory trees two, 

 with a few branches. Calcareous ring without any posterior
