Description : — Body subcylindrical with the anal portion 

 shghtly curved upward or dorsad, hi hfe, I observed five dehcate 

 tentacle -hke pedicels (or papilla}) around the anus. The 

 pedicels in tlie middle parts of the ventral trivium are somewhat 

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

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

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

 remind one of the small delicate papilla3 described by Thkel as 

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

 find any such arrangement as described by that autlior for that 

 species. The trivium is well pronounced showing numerous 

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

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

 There are two rows of pedicels in each ambulacrum. Tentacles 

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

 others and show scarcely any branches. Eespiratory trees two, 

 with a few branches. Calcareous ring without any posterior
