S.-W. Ireland Exped. (46) ; 93 fathoms, R. I. A. Exped., 1886, 
along with MWalmgrenia castanea on Spatangus Raschi. 'This species, 
which had been procured by the “Knight Errant,” in the Atlantic 
in 1880, is characterized as follows :— 
Head somewhat near that of Lagisca, having a pair of widely 
separated eyes posteriorly, and a larger pair on the lateral 
eminence. Palpi of moderate length, with rows of minute 
papillae. Body of considerable length and breadth; bristled 
segments 39-40. Dorsum has touches of brown pigment, pos- 
teriorly, as in Lagisca. The lateral nephridial eminences are 
prominent, but there are no papilla. Scales, 15 pairs, mottled- 
brown, covering the dorsum; first, small and rounded; rest, more 
or less ovoid ; border smooth, anterior and inner half studded ‘with 
small horny papille, outer and posterior areas have sparsely 
distributed large tubercles, with an ‘interrupted row along 
the posterior border. Dorsal bristles stout, moderately long, 
and slightly curved, with closely arranged spinous rows, and 
a short smooth tip. Ventral bristles bifid, the secondary process 
coming off at an angle. Dorsal cirri appear as if fusiform from 
the gradual nature of the dilatation and the long filiform tip, 
and have clavate cilia. Ventral cirri slender, with a few clavate 
cilia.
