one hull" lu three times as long- as broad; the third and following have produced overlapping 
spinous distal edges which are most developed along the distal side. P„ is from 1.5 mm. to 
1.7 mm. long, much smaller and more slender than l\ though with similar segments, of which 
the lirst is short, the second slightly longer than broatl, the third twice as long as broad, and 
the remainder elongated. P., is similar to P^ 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 e.\tremel\- 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, e.xceedingly 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 again as long as broad; the strong 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 I Br., (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 tha first is twice a
