tolerably flat. Disk only appearing slightly between the inner sides 

 of the II Br series. Anns LVIII 120 mm. Syzygies for instance 

 3 + 4 . . IG + 17 . . 22 + 23 . ., distally with an interval of 4 oblique arti- 

 culations. 1(5 segments pr cm. (13 if the syzygial pairs are counted 

 as units). The breadth of the arms at the middle 2,2 mm, I3r seg- 

 ments very short, L = ^/s — V4 X br. 



P„ + 60; 30 mm., about 20 T (37'" to 58*" segment) the tip 

 smooth; the teeth rather thin, low, h = ^2 of the br of the segments. 

 Piv or ?! 22—28 mm., + 20 T. P^ + 15 mm. with about 15 T. P., T, 

 11 mm . If Piv is lacking only 4 pinnules (P,i — P^) with teeth, Pg 9,:, 

 mm. Genital p. 14 mm. Distal p. 25; 11 mm., the 3 last segments with 

 small dorsal hooks. The proximal pinnules have the first 5 — 12 seg- 

 ments provided with small prominences; the notches between these 

 partly filled up by skin. 



Disk 40 mm. Mouth marginal. Anal funnel central, sharply set 

 off from the anal mterradius, L = 14 mm. No calcareous granules or 

 papillae in the skin. Colour brown; a somewhat lighter middle-line on 

 the dorsal side of the arm. On about 10 of the posterior arms 25 — 30 

 pairs of pinnules are without ambulacral furrows. The ambulacral 

 furrow of the arm, however, always remain.

 26 cases, V Br — s:2 (2 cases). Arms LXVIII, 130 mm. or shorter. 

 The formation of the arms as before. 



Br> 35 mm., > 80 segments. Teeth from the 40"' or 55"' to the 

 75* segTnent. Comb best developed about the 60"' segment. Pjy — P^ 

 decreasing, with teeth. All the arms with ambulacral furrows.
