1 specimen. 



Length, 20 mm. for the largest ; the greater number of specimens,

 height of body, 5 mm. ; breadth, 5 mm ; length of oral tentacles 

 5 mm. ; rhinophores, 4 mm. ; papillae, 3'5 mm. (for the largest). 



Form — Body firm, foot rather narrow, produced at the angles into 

 thin points, tapers gradually to a somewhat obtuse point at the tail. 



Oral tentacles broad and thick ; rhinophores slightly wrinkled ; 

 eyes very small, placed behind the rhinophores ; papilke very numerous, 

 the grouping obscure, continuous almost to the tip of the tail ; a bare 

 space continuous from head for three-quarters of the length of the back.

 rhinophores of the same colour, with frequently a line of opaque 

 white down the front, or in the rhinophores confined to the upper 

 third ; papill£e reddish brown or fawn coloured, with a very distinct

 on either side, curved inwards and of fair size. 



Laterals slender and acute, generally bearing 8 or 9 small and 

 irregular denticles.

 the trawl or dredge, so that it is not possible to state its natural
