HIMEROMETRA INOPINATA. 

 Antedon inopinata 1894. Bell, P. Z. S., 1S94. p. 398. 



Description. — Centrodorsal as in the other species of the genus. 



Cirri XXX, 26-34, stout, 30 mm. to 35 mm. long : the sixth or seventh seg- 

 ments are the longest, slightly broader than long to half again as broad as long: 

 the outer segments are slightly carinate, the carinationon the last six or seven 

 ending distally in a small spine. 



The forty-six arms are 140 mm. long ; nine of the IIBr series are 4 (3-1-4) 

 and two are 2 : the IIIBr series are all 4 (3-|-4) except one (internal) ; the remain- 

 ing division series are all 4 (3-|-4) except two IVBr series which are 2. The divi- 

 sion series are strongly convex and well separated as is usual in the genus. 



The proximal pinnules are very stout, but nearly smooth, the distal edges 

 of the segments being only very slightly swollen : all the segments are short, 

 about twice as broad as long in the proximal half, becoming squarish toward the
