ACTINOPODOUS HOLOTHUEIOIDEA. 253 



liolcs in the midcllo parts and two wings with holes extending out 

 laterally very much as in the similar bodies in the pedicels of 

 C. chronhjehni. Moreover, on the outside of these supports, there 

 are bodies, thinly scattered in a layer, which appear to be the 

 " reticulated ellipses," veiy much as in C. chronhjclmi. 



The smaller specimen is l.lcm. x 0.4 cm. large, with over 

 20 pairs of pedicels in each, ambulacrum. The pharyngeal mass 

 is entirely drawn in, and contrary to Lampeet's description, is not 

 unusually small, being 4 mm. long. In this specimen I have 

 detected tlie calcareous ring. One Polian vesicle was also visil)le, 

 but I could not ascertain the presence of a stone- canal. 



In both specimens the color was observed by Mr. Ikeda, the 

 collector, to bo reddish-orange in the fresh state. 



The specimens closely resemble C. chronhjehni, and if the 

 layer of reticulated ellipses in the pedicels extended to the body 

 perisome, T should not hesitate to assign them to that species ; 

 but as that is not the case T have put them in this species.

Siiecimcn examined : — One alcoholic specimen from Uraga Cliauuel, 150 

 fms. Collected by Mr. A. Owston on Ang. 6, 1899 (Sci. Coll., Si>ec. No. 1131). 



Description : — The specinien is 2.7 cm. long and 0.6 cm. broad. 

 It is spindle-shaped, tapering towards both extremities. It is 

 slightly curved so as to be concave on the ventral surface, but 

 this shape is probably accidental and owing to preservation. There 

 are two rows of pedicels along each ambulacrum. On the three
