shortly bifurcate near the apex, the short branch more j-e- 

 sembling a tooth. The dorsal cirri are of a black colour; the 

 ventral are pale. The anal cirri are of a light colour, short, 

 stout, and cylindrical. The habitat of this well-marked species 

 is unknown. The animal, at first sight, resembles a species of 

 Hipponoa.

Worm about 2| inches long. Body rounded-fusiform in shape, 

 thicker in the centre and narrower at each extremity, but the 

 posterior extremity narrower than the anterior ; composed of about 

 34 segments. It is of a light colour, and the whole body above 

 and below is dotted all over with numerous small, white, round 

 spots varying in size. The caruncle is long and narrow, extend- 

 ing over 4 or 5 segments. Ventral cirri white ; dorsal cirri long 

 and subulate and of a beautiful purple colour. Branchio) simply 

 branched. Bristles of both ventral and dorsal feet capillary 

 slender and simple, those of the dorsal tuft longer and stouter 

 than the ventral. 



This species, in its habitat and structure of the setae of the 

 feet, approaches the two species " inermis " of Quatrefages, and 

 '•'■ egena''^ of Grube, but differs from both in minor details.
