 incised and granulated. Longest diameter 6. shortest 3 mm. 



The proximal parts of thé animals narrow; the arms after about 

 Br 8 strongly bent outwards. Differ from the original specimen chiefly 

 by having fewer arms and a somewhat smaller size.

 close, radial tubercles arranged round a small, central cavity. — C. 

 XVI 55 — 75; 45 — 55 mm. in 5 groups separated by inconspicuous radial 

 interspaces. The 10*'' to the 25"' segments: L = 1 ' s — 1 '2 br. From 

 about the 30*'' segment L = br, from the 40*'' L = ^/s br, the distal 

 segments L = C 2 br. About the 25"' segment the cirrus becomes ser- 

 rate on the dorsal side in lateral in-ofile. The dorsal spine h = '/* <>i' 

 the br of the segment, on the distal segments smaller. Opposing spine 

 h = C.3 of the br of the segment. Terminal claw a little siiorter than 

 the penultimate segment. Cirri laterally pressed together. 



R— s h = '/3 br, with a small tubercle well limited. 1 Br — s 1 

 baso-laterally fused, somewhat broader than the R — s, in close synar- 

 thrial articulation with the axillary. No synarthrial prominence. Axil-
