Pi is 10 mm. long with 14 to 15 segments. The fost segment is slightly longer 

 thiin broad at the base with very slightly divergent sides; the second segment is half 

 again as long as broad at the base and more than twice as long as broad at the distal 

 end; the sides are rather strongly convergent in the proximal half, becoming parallel 

 in the distal half. From the distal end of the second segment the pinnule tapere 

 slowly and gradually to the tip, which is moderately slender, but not flagellate. The 

 third segment is twice as long as broad and tlie sixth and following are from two and 

 a half to three times as long as broad. 



l\ is 8 mm. long with 12 segments, resembling Pi but slightly less stout basally. 



P3 is 6.5 mm. long with 12 segments, resembhng P2 and scarcely or not at all less 

 stout basally than Pj but becoming more slender in the distal portion. 



P4 is 5 mm. long with 11 to 12 segments, less stout basally than P3 and becoming 

 very slender in the distal half. The distal ends of the segments are slightly produced 

 and finely spinous, this feature becoming conspicuous in the outer half. 



[Note by A.M.C] The paratjT^e from Siboga station 251 also has a development 

 of stumplike spines on the prox-imal ossicles but, besides those on the lateral parts of 

 the IBr,, there is a row of about six along the edge of each radial (see fig. 23,a). The 

 centrodorsal is 3.0 mm. in diameter and 2.6 mm. high in tins specimen and the arm 

 width at the first sj'zygy is 1.3 mm.
