(unpaired), a little shorter, and more delicate than anterior. 
Eyes posterior, lateral, circular, large, black. Of the 
tentacular cirri those of the first and second pairs are 
about half as long as the third ; the third (anterior supe- 
rior), reaches back to the 8th or 9th seg ; the 4th about two- 
thirds as long as the 3d. The first segment is a little longer 
than the 2d, about equal to the 5th. 
Dorsal cirri, on the anterior segments small, lanceolate 
(f. 39), becoming broader and heart-shaped (f. 40), while 
on the posterior segments they become again elongate, 
pointed, but with basal two-thirds of uniform width. 
Ventral cirri small, lanceolate, sometimes with one 
straight and one convex side, reaching slightly beyond the 
feet ; somewhat longer on posterior segments than on 
anterior. 
Anal cirri about the length of the last four segments, 
arising from a stout basal article forming about one-third 
their entire length. Terminal portion, subulate, acute. 
The extended proboscis is about one-third as long as the 
body. It increases regularly in diameter from its origin, 
ending in a crown of papillse. When highly magnified, 
longitudinal rows of cylindrical papillse can be seen. 
Color of the body, yellowish-white with numerous 
minute gray spots; appendages white. Dorsal cirri tinged 
with green. 
On shells ; 5 to 10 fathoms.
