The centrodorsal is flattened hemispherical, 2.5. mm. in diameter at the base; the dorsal 

 pole is slightly convex; the cirrus sockets are in one and a partial second marginal row. 



rhe cirri are about XV there are twenty-two cirrus sockets, but some are not tuil 



the longest cirrus stump is 4.5 mm. long to the distal dorsal edge of the fifth (the last 



remaining) segment; the first segment is about twice as broad as long, the second has the 



in length about equal to the median breadth, and is centrally constricted with the distal 



er produced, especially ventrally, where it overlaps the proximal end of the succeeding 



segment; the third is about twice as long as the proximal diameter, strongly constricted 



illy with prominent distal encls like those of the second ; the fourth is about three times 



as long as the median width, similar to the third; the fifth 

 is similar to the fourth but not quite so constricted centrally 

 and hence appearing slightly broader in lateral view. 



The radials are just visible over the edge of the 

 centrodorsal. 



The IHr, are short, about four times as broad as 

 the median length, with the proximal border produced into 

 a thin straight margin and the lateral borders slightly more 

 produced, and turned outward. 



The II Ir, taxillaries) are broadly V-shaped (inverted , 



with the lateral edges, which are half again as long as 



of the IMr,, turned ontward, unmodified, or with two 



or three broad scallops; the lateral thirds of the proximal 



r are produced and extended downward over the dist. tl 



r of the Ilïr,. and have a scalloped or tubercular border which is nearly parallel to the 



tvi distal edge opposite; the distal of the axillaries are plain and unmodified.
