 mm. in a single whorl. P' and 2'' segment shorter than long, 3'" seg- 

 ment cubical, 4"' and the following ones longer, a little hour-glass- 

 shaped. 0"' segment the longest, L = 1 ^ 2 X br. From 7"' or 8"' segment 

 a weak and indistinct dorsal prominence. The L of distal segments = 

 ^ 3 X br. The cirrus in the distal part somewhat pressed together and 

 in lateral view somewhat thickened. The terminal claw short, coarse, 

 a little longer than the penultimate segment. Cirri weak, small.

 with each other, distally broader, h = ' .5 X br. I Brax low pentagonal, 

 h = 1 3 X br, laterally united as usually also II Br : s 1. Primipostaxil- 

 laries fused inside. Bases of the arms smooth. The branches of the
