Three to five short, sharp arm spines, about half as long as a joint. Disk smooth 

 and flat, with scales, radial shields, and mouth shields all small. 



(Type specimen from Station 157.) Diameter of disk 21 mm. Width of arm 

 close to disk 3*7 mm. Six or seven small rouuded mouth papillae on each side, the 

 outer three being closely soldered together ; at apex of jaw a clump of three larger 

 papillae. Mouth shields triangular, with an obtuse angle within, and the outer edge 

 much rounded ; length to breadth 3'5 : 4. Side mouth shields following inner angle 

 of the mouth shield, rather narrow without, where the mouth tentacle pores encroach, 

 wider within, where they scarcely meet. First under arm plate broad triangular, 

 or broad rounded hexagonal, with outer edge much curved, and a very blunt angle 

 inward ; second plate nearly square, with rounded corners ; the next two rudely 

 semicircular, with outer edge straight, or broad much rounded pentagonal, with an 

 dl-marked angle inward ; the rest are transverse oval, with a peak inward. Side arm 

 plates wide, a little swollen, meeting below beyond the disk, separated above by the 

 upper arm plates, which are much broader than long, with outer edge broken in three 

 angles or curved, and the lateral sides forming an angle. Disk arched, but not thick, 

 covered above and below with small, thin, closely soldered scales, the six primaries 

 being small, circular, widely separated plates. Eadial shields much longer than wide, 

 with a sharp angle inward, separated by a wedge of disk scales ; length to breadth 

 4*5 : 2. Genital scales very narrow, covered by fine scaling, bearing on their free 

 edge a close row of very fine, square papdlae, which increase a little in size as they 

 appear above to form the arm comb. Three tapering arm spines, about half as long as 

 a joint ; the upper one the longest. Larger specimens have five or more spines. On the 

 mouth tentacle pores there are seven or eight close-set, toothdike scales on either side ; 

 the next two pairs have six or seven on each side ; just beyond the disk there are four 

 scales on the inner side, and the same number of smaller ones on the outer. Colour in 

 alcohol, grey.
