The centrodorsal is long, rounded conical, about 3.5 mm. in diameter at the base and 

 about 3.0 mm. from the apex to the interradial margin; the dorsal pole is 2.0 mm. in diameter, 

 slightly concave; the cirrus sockets are arranged in four or five closely crowded regularly 

 alternating rows, or four closely crowded alternating columns, in each radial area. 



-The cirri are about LXX, 43 — 47, 25 mm. to 30 mm. long, moderately slender; the 

 first segment is very short, the second about twice as broad as long or even somewhat broader, 

 the third nearly as long as broad, the fourth about one third again as long as broad, the 

 sixth-eleventh or -twelfth about twice as long as broad; the following gradually decrease in 

 length so that the last ten or eleven before the penultimate are twice as broad as long; on 

 the fourth and following the distal dorsal edge projects slightly, this on the short outer segments 

 becoming a prominent median carination with a convex crest occupying the entire dorsal surface 

 of the segment. 



The ends of the basal rays are visible as rather prominent rounded triangular areas in 

 the angles of the calyx. 



The radials are rather prominent, and are nearly as long in the median line as laterally; 

 the plane of their mid-dorsal line is nearly go° divergent from the dorsoventral axis. 



The IBrj are four times as broacl as long in the median line; the lateral edges are 

 from one third to one half again as long as the median length, strongly convergent, continuing 

 in the same direction as the lateral portion of the distal border of the radials on either side; 

 the median third of the proximal border is slightly convex ; the distal border is deeply incised 

 by a posterior rounded projection from the axillary; the distal half of the lateral borders is 

 produced in the form of a prominent tubercular process. 



The IBr, (axillariesj are about as broad as long, the anterior angle slightly produced, 

 the anterior sides making approximately a right angle with each other; a strong rounded 

 posterior process extends to about the same distance below the line passing through the two 

 lateral angles that the anterior angle reaches above it; just below the lateral angles there is 

 a prominent tubercular process; the distal edges, like.the lateral portions of the distal edge
