ECHINODERM.A OF THE INDIAN MuSEUM, PART VII. 



Cirri XVIIl, 17-18, 20 mm. long; first segment twice as broad as long, second 

 nearly or quite as long as broad, third to fiftla twice as long as the proximal dia- 

 meter, sixth slightly shorter, a more or less marked transition segment; following 

 segments gradually decreasing in length, the terminal segments being only slightly 

 longer than broad ; penultimate segment about as long as broad ; the third to 

 the sixth segments are very strongly " dice-box " shaped, with the distal edge 

 all around produced, except on the dorsal side ; from the seventh onward both 

 these features become less marked, and the cirrus becomes somewhat compressed

laterally; there are no dorsal spines; opposing spine sharp, prominent, arising 

 from the entire dorsal surface of the penultimate segment, equal to about one 

 lialf of the lateral diameter of tliat segment in height ; terminal claw equal in 

 Kengtli to the penultimate segment, stout and strongly curved. 



Disk with a few rather large plates along the ambulacra, and well plated in 

 the anal area. 



Ends of the basal rays visible as small tubercles in the angles of the calyx ; 

 radials projecting slightly l)eyond the centrodorsal, slightly concave distally ; 

 IBr, and IBr.j united by pseudosyzygy, forming an oblong pseudosyzygial pair
