 an adjoined statement).

Description: 



Centrodorsal discoidal a little pressed down in the middle, l 1 /--- 3 mm in dia- 

 meter, in full-grown specimens almost covering the radials, in immature ones leaving 

 them bare. 



C. VI— IX {purpurea) X— XVIII {pectinata), 9 — 15 (usually 10 — 12) 5— 9 mm. 

 First segment short, the length is half the breadth, closely united with Cd. Second 

 segment as long as it is broad. The length of third till eigtth segments a little 

 greater than the breadth, viewed sideways with very oblique joints. This appearance 

 of theirs is caused by the segment proximally having a deep dorsal excavation and 

 a powerful ventral prominence, the distal part of the segment having a correspon- 

 ding dorsal prominence and a ventral concavity. No dorsal spines developed except 

 opposing spine. The latter one is small, distinct, a fourth of the breadth of the 

 penultimate segment. Terminal claw long, pointed, in its proximal part acutely 

 (60—90°) bent, one and a half times as long as the penultimate segment.
