The centrodorsal is small hemispherical or subconical, the polar area rather small 
and papillose. 
The cirri are XXX — XL, 24 — 28, very slender, 25 mm. long; the first two segments 
are short, the third is about half again as long as broad, and the remainder are four or five 
times as long as broad, or even longer; the antepenultimate segment tapers slightly from the 
proximal to the distal end ; the penultimate segment is about half as long, and tapers to the 
base of the terminal claw; the last is about half as long as the penultimate segment, perfectly 
straight, and tapers to a sharp point; the cirri are perfectly smooth with no trace of dorsal 
processes on the distal segments, nor of an opposing spine. 
There are no basal rays. The radials are just visible in the median line, extending up 
in the interradial angles in the form of a triangle. The I Br, are oblong, about two and one 
half times as broad as long, widely separated laterally. The IBr., (axillaries) are almost 
triangular, with the posterior edge slightly convex and the anterior angle long and acute ; 
they are .somewhat broader than the IBrj. 
The ten arms are from 60 mm. to 70 mm. long. The first brachial is wedge-shaped, 
longer outwardly than inwardly, the inner sides in apposition basally; the second brachial is 
similar, but rather larger and more irregular in shape; the first syzygial pair (composed of the 
third and fourth brachials) is approximately as long as wide; the following brachials to the 
eighth are slightly wedge-shaped, not quite so long as broad; the second syzygial pair (com- 
prising the ninth and tenth brachials) is not quite twice as long as broad; the succeeding 
brachials are obliquely wedge-shaped, about as long as, or rather longer than, broad, becoming
