second longer, the third about as long as the median diameter; the fifth and sixth arc tiie 
longest, about as long as their distal diameter or slightly longer; the segments following the 
eighth are subequal, slightly longer than broad; the third-seventh segments are constricted 
centrally, with strongly expanded distal ends which overlap the bases of the succeeding segments, 
especially dorsally; beyond the seventh this character gradually dies away. 
The distal edge of the radials is just visible beyond the edge of the centrodorsal, and 
is ornamented with a row of small regular tubercles; the IBr series (comprising the first two 
ossicles beyond the radials) is oblong, not quite twice as broad as long, with the proximal, 
distal and lateral edges everted; the lateral edges are beaded like the distal edge of the radials; 
the proximal edge is faintly scalloped and bears a prominent median tubercle; the distal edge 
has the median third of the eversion thickened and standing up vertically as a high transverse 
ridge; the pseudosyzygial line is finely beaded; the first brachial is oblong, about three times 
as broad as long; the proximal edge is slightly everted, with a prominent, though small, median 
tubercle; the distal edge is strongly everted and thickened, this thickened and everted border 
being more or less divided in the middle; the second brachial is very slightly larger than the 
first, about twice as broad as long; the distal edge is everted, the central third of this eversion 
being thickened and produced; the first syzygial pair (composed of brachials 3 + 4) 's about 
as long as broad, or slightly longer than broad; the proximal edge is slightly everted, with a 
minute median tubercle; the distal edge is slightly everted, with a slightly larger, more or less 
transversely elongate, median tubercle; the following brachials have finely spinous distal ends 
which are not produced nor everted ; a slight median tubercle is visible on the proximal border 
of the brachials up to the first or second beyond the second syzygy ; there is a very low and 
faint median carination on the first syzygial pair and on the following brachials which is 
accentuated by being light in colour, bordered with dark on either side; on the triangular 
brachials this becomes zigzag as in the other species of the genus. 
The five arms are 60 mm. long. 
Pc is 3 mm. long with 10 segments; the first bears a very large fan-shaped, rounded 
or distally truncated carinate process which is about as high as the lateral diameter of the 
segment; the second bears a high carinate process half as high as the lateral diameter of the 
segment, of which the crest is parallel to the longitudinal axis of the pinnule; the following 
segments are similarly, but diminishingly, carinate; P, is similar; Pa is 5 mm. long with 11 or 
12 segments, of which the first is short, the second nearly as long as broad, the third about 
as long as broad, and the distal twice as long as broad; the pinnule is rather slender and not 
greatly enlarged, rather strongly prismatic ; the distal edges of the third and following segments 
are slightly produced and finely spinous, with prominent spines at the angles of the prism; the 
ventral borders of the segments bear very numerous fine spines ; the first segment has a strongly 
rounded carinate process, and the second and third are narrowly, though sharply, carinate; P, 
is similar to Pa; Pb is 4 mm. long with 13 segments, slightly more slender than Pa; the first 
segment is short, the second slightly longer, the third about as long as broad ; the distal segments 
are much elongated with a few long spines on the everted distal edges; the proximal segments 
are not carinate: the following pinnules are similar, though weaker and more slender with
