ill heij^ht does nol reach a ihird o( the diamcler of ihe segment; the terminal claw is about 
as long as the penultimate segment, and is moderately curved. 
There are no basal rays. 
The radials are only visible in the interradial angles. The Ibr, are very short with a 
concave anterior border which in the median line nearly reaches the straight posterior border. 
The I Br., (a.xillaries) are rou_L,dily rhombic with a rounded posterior prolongation; the anterior 
angle is sharp and greatly produced. The IBr series are normally just in ajtposition laterally, 
but are not lateralK- tlaltened. 
The lo arms are probably between 50 mm. and 60 mm. long. The lirst brachial 
exteriorly is about half as long as broad, but becomes reduced almost to a point interiorly, 
and is deeply incised in the median line by the considerably larger irregular second brachial. 
The first syzygial pair (^composed of the third and fourth brachials) is wedge-shaped, much 
longer interiorly than exteriorly. The following brachials are rather short, after the twelfth, 
becoming more triangular, about as long as broad. The proximal brachials as far as the 
eighth have slight alternating lateral tubercles. The edges of the ossicles of the IBr series and 
the lower brachials are everted, prominent, and very spiny. 
Syzygies occur between the third and fourth, ninth and tenth and fourteenth and fifteenth 
brachials, and distally at intervals of two oblique muscular articulations. 
Pj is 7.5 mm. long, slender, composed of 35 or more short segments, those in the 
pro.ximal half about as long as broad with the corners cut away, those in the distal half 
becoming gradually somewhat elongated, the very slender terminal segments being about three 
times as long as broad. P., is 7 mm. long, considerably .stouter and less flexible than P,, with 
about 15 segments of which the first three are about as long as broad and the following 
become elongated, the sixth over twice as long as broad and the terminal four or five times 
as long as broad. The following pinnules as far as P, are similar, after which the pinnules 
become longer and more slender with the first two segments slightly enlarged, the first short, 
the second about as long as broad, the remainder elongated. 
The colour in spirits is white with a median line of black on the IBr series and the 
lower portion of the arms, beyond which each syzygial pair bears a transverse black band or 
large black spot; ventrally the disk is black, and the perisome of the arms is yellowish 
banded with black.
