WEST INDIAN STAEFISHES 117 



which, form a very regular marginal fringe, but they are shorter 

 than those of the dorsals. The interspaces between these plates 

 and between the two rows are narrower than those of the dorsal 

 surface and contain no papular pores. The two rows are much 

 alike, but the lower ones are larger. 



The adambulacral plates are similar in form, about one-fourth 

 as large, two of them corresponding to one inferomarginal. Each 

 one bears a crowded group of slender, rough, hyaline spinules on 

 the actinal surface, and a crowded furrow-series of four to six 

 somewhat larger ones. Within the outline of the disk these 

 spines, and also those of the actinal side, become much longer 

 and setiform. 



There is a small triangular group of interactinal plates, spin- 

 ulated much like the dorsals, with rough hyaline spinelets. 



The dorsal plates of the disk are rounded, smaller than those 

 of the rays, but spinulated in the same way. The madreporite 

 is small and covered with similar spinules. 



Taken by the Bahama Expedition at station 16, of Havana in 

 200 fathoms, (specimen described above), and at station 7, off 

 Havana, 140 fathoms, one specimen. The type was from off 

 Guadeloupe. 



The tuberculated specimens taken off Bermuda, in 30 fathoms, 

 by the Challenger and referred to C. longipes by Sladen, belong 

 apparently to this species.

Sladen states that his Bermuda specimen is young, and has 

 some nodosites, which recall those of C, nodosm Perrier. 



Probably it was a young specimen of the latter, which occurs 

 off Florida in similar depths. C. longipes is a Mediterranean 

 species, ranging to the Azores.

 fathoms (Sladen), East Atlantic, in 102 to 1139 meters (Per-
