second longer, the third about as long as the median diameter; the fifth and sixth are the 

 lono-est, about as long as their distal diameter or slightly longer; the segments following the 

 eio-hth 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) is 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 t'runcated 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 l is similar; P a is 5 mm. long with 11 or 

 1 2 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 a 

 is similar to P a ; Pb is 4 mm. long with 13 segments, slightly more slender than P a ; thé 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 dista! edges; the proximal segments 

 are not carinate: the following pinnules are similar, though weaker and more slender with
