tween the latter and the commencement of the hispid rows is long. 



According to McIntosh, this species somewhat approaches 

 Tlarmothoé lamellljera, but should differ from it in the absence of 

 pear-shaped processes on elytra, which are also apparently less 

 minutely spinous. Further, the dorsal bristles in H. lamellifera 

 do not show so long a smooth region at the tip, and the secondary 

 process or spur of the inferior series should show a different angle. 



Habitat : — Dredged off Yokohama, Japan, in 5 to 50 fathoms 

 (" Challenger ").

Body small and rather elongate, 13 mm. long and 3 mm. 

 broad, comprising 39 setigerous segments. 



Prostomium furnished with four very distinct eyes, two of 

 which are placed wide apart at its posterior border, while those of the 

 anterior pair are longer and are situated slightly in front of the lateral 

 prominence. The latter are fully seen only from the side. Paired 

 tentacles rather thick at base but tapering at end. Subtentacles short, 

 with filiform tip. Dorsal cirri somewhat slender ; their tip long 

 and filiform. Ventral papilla a well-marked cylindrical process. 



Elytra occur in 15 pairs on segments 2, 4, 5, 7 21, 23, 



26, 29, 32. They are covered all over with numerous, rather distinct, 

 nearly cylindrical papillae, and show on the posterior parts of their 

 surface and along the edge a somewhat dense growth of cilia, longest 

 and most abundant along the outer Ijorder. Toward the inner 

 posterior Ijorder of elytra the papillae become shorter, more 

 sparse and clavate in shape.
