Pc is 6.5 ipm. long and composed ot 15 segments, rather stout basally, but tapering 
to a very delicate tip; the first segment is short, the following increasing in length and becoming 
about as long as broad on the fourth or fifth, and twice as long as broad terminally; the 
second-sixth bear a narrow sharp straight edged carination which is equally high on each ; the 
prismatic edge is sharp; the outer surface of the pinnulars (between the prismatic angles) is 
llat or very slightly concave. P^ is similar, 6.5 mm. long with 1 3 or 14 segments. P^ is 11 mm. 
long, much larger and .stouter than those preceding, but evenly tapering and becoming very 
delicate distally, composed of i 5 segments, at first short, becoming about as long as broad on 
the fourth and three times as long as broad distally; the second-fourth ^bear a low even cari- 
nation; the second and following have the distal edges all around produced and finely spinous; 
following pinnule (on the opposite side of the arm) 11 mm. long with 15 segments, exactly 
resembling P^; Pi, S mm. to 10 mm. long with 19 segments, very slender; the proximal segments 
are as small as the first segments of P, ; the first segment is short, more or less crescentic; 
the second is about twice as broad as the median length ; the third is not so long as the 
distal breadth ; the fourth is from one third to one half again as long as broad ; the following 
gradually increa.se in length, after the eighth becoming from three to four times as long ^s 
broad; the fifth and following have sHghtly produced and spinous distal edges; P^ is 10 mm. 
or II mm. long with 18 or 19 segments, similar to Pb; Pc is 8 mm. long with 17 segments, 
very slender, more slender than Pb, with more elongated segments; P^ is similar to Pc; P,i is 
7 mm. long with 18 segments, resembling Pc, but even more delicate and with more elongate 
segments; P. is similar to Pa; Pe is 6.5 mm. long with 16 segments, resembling Pa; P„ is 
siniilar to Pe ; the distal pinnules are 8.5 mm. long with 20 excessively slender segments. 
The disk, is naked. 
The colour is white. 
Another specimen has the arms 80 mm. long, and the cirri XXVIII, 22, 21 mm. long; 
the lateral and proximal edges of the I Br series are bordered with numerous regular tubercles, 
which give the impression of rows of little beads. A specimen similar to that just mentioned, 
with arms 80 mm. long, has the distal border of the radials also beaded. There are 10 additional 
specimens essentially resembling these. Three very small specimens with arms 20 mm. long and 
cirri with 10 segments have, as is usual in small comatulids, greatly elongated cirrus segments 
with swollen articulations. 
Some of the examples have a few small light brown dots on the dorsal surface of the 
arms which on the brachials tend to form lines along the zigzag dorsal carination.

The centrodorsal is discoidal, the flat dorsal pole 2 mm. in diameter; the cirrus sockets 
are arranged in two rows. 
The cirri are XVII, 17—22 (usually 21 — 22), 10 mm. to 11 mm. long; all the segments
