Pc is 6.5 mm. long and composed of 15 segments, rather stout basally, but tapering 

 to a very delicate tip; the fïrst 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 vvhich is equally high on each ; the 

 prismatic edge is sharp; the outer surface of the pinnulars (between the prismatic angles) is 

 flat or very slightly concave. Pj is similar, 6.5 mm. long with 1 3 or 14 segments. P a is 11 mm. 

 long, much larger and stouter than those preceding, but evenly tapering and becoming very 

 delicate distally, composed of 15 segments, at lïrst 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 a ; P b 8 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 ; thé 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 increase in length, after the eighth becoming from three to four times as long as 

 broad; the fifth and following have shghtly produced and spinous distal edges ; P 3 is 10 mm. 

 or 11 mm. long with 18 or 19 segments, similar to Pb; P c is 8 mm. long with 17 segments, 

 very slender, more slender than Pb, with more elongated segments; P t is similar to P c ; Pa is 

 7 mm. long with 18 segments, resembling P c , but even more delicate and with more elongate 

 segments; P. is similar to Pd; P e is 6.5 mm. long with 16 segments, resembling P<j; P G is 

 similar to P e ; 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 IBr 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. 



Sorae 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 n mm. long; all the segments
