ACTINOPODOrS HOLOTHUrjOIDEA. 247 



Jicmarks : — Wliatcvor may be the relation of this species to 

 otlier species move or less resembling- it, there can be; no donbt 

 that the specimens before me belong to the same species as tliat 

 described as C. multipes by Thkel from the same locality. The 

 specimen is cylindrical and rather large, being 6.7 cm. long and 

 2.5 cm. broad. It ends bluntly at both ends. There are two 

 distinct rows of nnmerous crowded pedicels along each of the five 

 ambulacra, and there are clearly no pedicels in any of the inter- 

 ambulacra. The specimen in alcohol shows many transverse 

 wrinkles. I can not detect any calcareous teeth around the anus. 

 Owing to the imperfect state of his specimen, Thkel was unable 

 to make out the calcareons ring or other anatomical details. 



Tentacles ten ; the two ventral ones small. Polian vesicles 

 two. Stone-canals in the dorsal mesentery two in number, witli 

 lateral madreporic bodies at the end. Calcareons ring as in C. 

 chronhj'clvii, the midventral radialia and the Uxo adjoining ventral 

 interradialia being fused together into a piece whieli is anteriorly 

 three-pointed and posteriorly runs into two prolongations. Other 

 radialia and interradialia are separate ; eacli of tlie radialia being 

 triangular in slrijx', pointed anteriorly and with two jjosterior 

 prolongations ; the interradialia sagittate, witlient any posterior 

 prolongations. The retractor muscles bipartite, and liecoming free 

 at about ',■ of the body-length from the antericn' end. 



Calcareous deposits are tables only. These are thickly crowded. 

 The disk is irregularly rounded or multiangular ; its shape commonly 

 oval or elongate fusiform with one or both ends slightly drawn 

 out (textfig. 49 b). They show a number of holes, among which 

 four principal ones can be easily recognized in most cases. In 

 the larger tables, the si)ire is generally reduced to a single arch 

 stretching longitudinally between two of the principal holes. Some
