From St. 45 (1 sp.) 55 (1), 50 (1) = 3 specimens. 



Sp. 1 (St. 59) Cd 2,2 mm., free dorsal pole 1 mm. C. XVII, 

 10—11; 5—7 mm. in a single or double whorl; 1** segment short, 2'' 

 strongly hour-glass-shaped L = li,2Xbr; ;V' L =-- 3 X br, 4'" somewhat 

 shorter L = 2i/2 X br. 5"' segment a transition segment. Dorsal spine 

 small, indistinct, on the distal part of the segment. Penultimate seg- 

 ment L = br with opposing spine; h of this one about = Va X the br of 

 the segment. Terminal claw L = + 2 X the preceding segment, strongly 

 curved. 



R_s concealed. I Br 1 h = i/4 X br, partly hidden by Cd. I Brax 

 h='/3X br, almost triangular. A syzygy between I Br 1 and 2. All 

 the way from 1 Brax the margins of the segments are distally bent 

 outwards and very spiny. II Br:s are 4, III Br:s 2 (1 + 2). Arms 

 XXVIII 50—70 mm. Br: 1 + 2 except when the arm originates from 

 a I Brax; then occurs Br 1—2 3 + 4. Br 1—7 discoidal, then oblique 

 joints. 16 segments pr cm. (12 if the syzygial pairs are counted as 

 units). The breadth of the arms 0,7 mm. Segments distally: L = IV2X 

 br, slender, hour-glass-chaped.
