The centrodorsal is discoidal, with a bare flat polar area 3.5 mm. in diameter. 
The cirri are XI\', iS — 20, 23 mm. long; the first segment is very short, the following 
gradually increasing in length to the fourth, which is .slightly broader than long, and the fifth- 
seventh, which are as long as, or very slightly longer than, broad; the eighth, a transition 
segment, is about half again as long as the median diameter; the ninth is about as long as 
the median diameter; the following gradually decrease in length so that the last three or four 
before the penultimate are about twice as broad as long; the distal dorsal edge of the eighth 
is thickened; on the succeeding this soon becomes a thick rounded dorsal spine of the type 
characteristic of the genus. 
The ends of the basal rays are visible as small but prominent rounded tubercles in the 
angles of the caUx. The radials are concealed. 
The I Br, are ver)' short, about twice as long on the lateral border as in the median 
line, in lateral apposition for the basal two thirds but in the distal third diverging in nearly 
a straight line, extending well up in the angles of the calyx; they bear a low blunt median 
carination. The IBr, (axillaries) are rhombic, twice as broad as long, the lateral angles in 
contact with those of their neighbors; the cutting away of the distal angles of the IBr, forms 
large and conspicuous water pores just beneath the appo.sed angles of the axillaries; in the 
median line of the axillaries there is a low blunt median carination : from the lateral angles a 
horizontal ridge runs inward for one third to one half of the distance to the median line, 
sometimes in the middle of the angle, sometimes toward the proximal side, where it branches, 
one branch curving downward and becoming a produced proximal border which runs to the 
median carination, the other branch running as a thickened rim along the distal faces of the 
axillary, or as a ridge just within the distal edges, sometimes meeting just proximal to the 
distal apex, but usually forming a broad curve beyond which is the apex. The IIBr series 
are 2 ; the proximal and distal edges of the elements of the IIBr series are moderately thickened 
and everted; there is a slight rounded median carination; the axillaries have thickened distal 
edges and produced proximal edges, the latter running in broad curve in the central part of 
the segment, in the lateral third or fourth running nearly or quite straight to the lateral angle. 
The edges of the first two brachials are modified like those of the elements of the IIBr 
series; there is a trace of a median carination. 
P, is 10 mm. to 12 mm. long with 17 — 21 segments which become about as long as 
broad on the si.xth. and nearly twice as long as broad terminally; the pinnule is evenly 
tapering, rather stronglj- prismatic, and but little enlarged; the second-fifth segments are sharp 
distally, though not distinctly carinate; the outer segments have the distal angles rather 
prominent, though not produced. l\ is 6.5 mm. long with 12 segments, shorter, more slender, 
and slightly less tapering than P, ; the pinnule is strongly and sharply prismatic, the profile 
of the prismatic angle on the outer segments being sligthly convex; the distal segments have 
slightly prominent distal angles. P3 is 6 mm. long with 1 2 segments, similar to P. but tapering 
-slightly more rapidly distally. The following pinnules resemble P.,. The distal pinnule are slender 
o mm. long with 17 segments.
