one half to three times as long as broad ; the third and following have produced overlapping 

 spinous distal edges vvhich are most developed along the distal side. P, is from 1.5 mm. to 

 1.7 mm. long, much smaller and more slender than P 1 though with similar segments, of which 

 the first is short, the second slightly longer than broad, the third twice as long as broad. and 

 the remainder elongated. P 3 is similar to P a but very slightly smaller, with only a very slight 

 production of the distal dorsal edges of the segments. The distal pinnules are from 2 mm. to 

 4 mm. long, and extremely slender.

The centrodorsal is flattened hemispherical, very low, bearing two irregular rows of 

 cirrus sockets. 



The cirri are XV — XXV, 8 — 9 (usually 8), 4 mm. long, exceedingly slender, the much 

 elongated segments with greatly expanded ends; the first segment is about twice as broad as 

 long, the second from two to two and one half times as long as the diameter of the expanded 

 distal end, the third and fourth the longest, about three times as long as the diameter of the 

 expanded distal ends; the following decrease slowly in length so that the antepenultimate is 

 about twice as long as the diameter of its expanded distal end, and the penultimate is from 

 one third to one half asain a s long as broad; the stront constriction of the middle of the 

 segments decreases in amount distally; the opposing spine is terminal, prominent, in height 

 reaching nearly half the distal diameter of the penultimate segment; the terminal claw is about 

 as long as the penultimate segment, rather stout, strongly and evenly curved. 



The distal borders of the radials are even with the rim of the- centrodorsal ; their distal 

 angles are slightly separated. 



The IBrj are about three times as broad as the lateral length, which is twice the median 

 length ; the lateral edges converge slightly, and are widely separated from those of their neigh- 

 bors; the lateral portion of the proximal and distal edges is sometimes slightly thickened. 



The IBr., (axillaries) are rhombic with the lateral angles truncated, twice as broad as 

 long, widely separated from their neighbors. 



The 10 arms are from 15 mm. to 20 mm. long, and slender; the brachials have somewhat 

 prominent very finely spinous distal ends; syzygies occur between the third and fourth brachials, 

 again between the ninth and tenth and fourteenth and fifteenth, and distally at intervals of 

 three oblique muscular articulations. 



Pj is from 2.3 mm. to 3.5 mm. long with 9 — 10 segments of which the first is twice a
