The centrodorsal is discoidal, moderately thick, the sides sloping inward rather strongly; 
the dorsal pole is from i mm. to 1.5 mm. in diameter, and flat; the cirrus sockets are arranged 
in two closely crowded irregular rows. 
The cirri are XXV, 22 — 23 (usually 22), 23 mm. long; the apical cirri are 12 mm. 
long with I 7 segments. The cirri are greatly elongated with greatly elongated segments, slender, 
tapering gradually from the base to the tip,^ though rather more in the first three or four 
segments than subsequently. As a whole the cirri strongly suggest an approach to the type
