slighüy longer segments which bear a few conspicaous spines on their overlapping 



distal ends; the dist. il \ slender, 7 mm. long with 17 segments of which 



the third and f( itly elongated; the third bears a narrow carination. 



.\ imilar t<> the one described; the third, with the same arm length 



and numbei production of the dist. il edges of the lower brachials and of the 



proximal pinn iore pronounced. 



I 3 from Stat. 294 vary in arm length fróm 27 mm. to 65 mm., most 



1 55 mm. and 65 mm. Even in the smallest the carination of the carlier 



as strong as in the adults, though more rounded and not truncate 



.'.ly: bnt only the median swollen portion of the eversion of the borders of the 



ped. In these specimens the carination of the first pinnule segment is often 



mwch higher than the transverse diameter of the segment, fan-shaped, and with a dentate crest. 



A specimen from "Albatross" Stat. 5355, Philippine Islands, 44 fathoms (Cat. X" 36009 



U. S. Nat. Mus.), appears to belong to this species.

< )ne of the specimens may be described as follows : 



Centrodorsal discoidal, the cirrus sockets arranged in two rows; the bare dorsal pole is 

 2.5 mm. in diameter. 



The cirri are XXI, iS. 12 mm. long, comparatively slender; the segments increase in 

 length to the fourth-sixth, which are about twice as long as the proximal diameter; the distal 

 ;ht are about as long as broad; the longer segments are centrally constricted with 

 ly Haring 'distal ends. 



The distal edge of the radials and the proximal border of the IBr, are slightly thickened 



and turned outward; there is a slight tubercle in the centre of the latter; the distal edge of 



IBr series is everted, the middle fourth thickened into a transversely elongate tubercle; the 



central half of the distal border of the proximal discoidal brachials is everted and spinous ; the 



■ f the following brachials is slightly produced and finely spinous; the lateral borders 



of the IBr series are finely dentate. 



Pi is 5 mm. long, composed of 12 segments; P, is 7.5 mm. long with 15 segments; 



12 mm. long with 16 — iS segments, at first short, becoming about as long as broad on 



fourth, twice as long as broad on the eighth or ninth, and slightly longer terminally ; the pinnule 



> only m ly stout; the segments overlap slightly along the prismatic crest, where there is 



■ lopment of spines on their distal ends; in profile the prismatic crest is slightly notched". 



pecimen is similar; it has arms 50 mm. long. 



It is quiti ihat this form should be regarded not as a distinct species, but as 



marked variety of /:'. indtvtsus, bearing the same relation to the latter that Cotylo- 



'otylotnetra gracilicirra omata.
