Interbrachial areas below covered by the very large, elongated 

 oral shields and about ten small plates like those on the sides of 

 the areas; each oral shield is about 1 '5-1 '75 mm. long by 1 mm. 

 wide; the distal margin is well rounded, the lateral margins are 

 more or less indented by the genital slits and the inner angle is 

 quite acute. Adoral plates narrow, meeting within, distinctly longer 

 than inner margins of oral shield. Oral plates distinct, proximally 

 elevated or swollen. Oral papillae, 3 on a side and one at apex of 

 jaw, the distalmost very wide but low. Second oral tentacle pores 

 opening entirely outside mouth slit, guarded by about 5 scales on 

 one side and 4 on the other. First under arm-plate very large, 

 tetragonal but much wider without than within, in contact with 

 distal end of adoral plate on each side; second plate widely separat- 

 ed from it, small, triangular; succeeding plates small and widely 

 separated, much wider than long, somewhat pentagonal with a 

 proximal angle and a convex distal margin. Side arm-plates very 

 large, broadly in contact below, and, beyond the basal seven or 

 eight segments, above; each carries 3 well-spaced, blunt cylindrical 

 arm-spines; these are subequal or the uppermost is longest and at 

 base of arm are nearly equal to a segment but distally they barely 

 equal half a segment. Basal tentacle-pores large but rapidly decreas- 

 ing in size; the first has 3 (or 2) scales on one side and 2 on the 

 other; the second and third have one on each side, but after that 

 there is only a single tentacle-scale to each pore. - Colour, nearly 

 or quite white ; colour in life unknown.
