I see no reason to doubt that the echinothurid to which Bell 

 refers (I. c.) as allied to Phormosoma tenne is identical with one in 

 the PIETER FAURE collection, which I believe to be the Caribbean 

 species E. petersii. The only difference noticeable is that the primary 

 tubercles appear to be somewhat larger on the abactinal surface, than 

 they are in a Caribbean specimen of slightly larger size. The PIETER 

 FAURE specimen is only about 125 mm. in diameter and is in poor 

 condition. The surface is so badly rubbed I could find no tridentate 

 pedicellariae and there are very few unbroken spines. There is a 

 small vial with hoofed spines in it accompanying the specimen but 

 there is no direct evidence to show that they actually came from 

 this specimen. They probably did however.

PEDINIDAE. 



This family, containing but one Recent genus, has not hitherto 

 been found in southern seas. One species is known from near the 

 Kei Islands but all the others are from north of the equator. The 

 occurrence therefore of a Coenojifdina from deep water off the Cape 

 is a matter of very great interest. It appears to be an undescribed 

 form and may be named for the locality where it occurs, as two of 

 the other species have been.
