NO. 15 RECENT CRINOIDS IN BRITISH MUSEUM CLARK 2/ 



the IVBr series (when present) are 4 (3+4). The division series 

 are strongly convex and widely separated as is usual in the genus. 



P D is 18 mm. long with from thirty to thirty-two (usually the lat- 

 ter) segments, which are nearly twice as broad as long in the proxi- 

 mal half, but become about as long as broad in the distal third and 

 terminally as long as broad ; after the fourth or fifth the segments 

 develop strongly everted and produced distal dorsal edges, this 

 character gradually dying away in the distal third of the pinnule ; 

 this eversion is smooth and not serrate. The proximal pinnules are 

 very stout, but also very long, and taper distally to a flagellate tip as 

 in H. mag ni pinna; but the eversion of the distal ends of the seg- 

 ments is much greater than in that species, and the cirri are stouter. 



2. Kolumaduli, Maldives; jcV fathoms. — One specimen ; the cirri 

 are XXXV, 27-29 ; there are fifty-one arms ; only one of the division 

 series (a IIIBr series internally developed) is 2, all the others being 

 4(3-)-4); the proximal pinnules are exactly as in the other, 18 mm. 

 to 21 mm. long.
