terete, the short clubs with numerous suckers, of which the lower

R. PAPILLIFERA, Jeffreys. 



Body stout ; back of mantle, head and arms covered with 

 small whitish pimples; arms stout, all except the ventral pair 

 connected below by a strong web; suckers bead-like, pedicelled, 

 in two series throughout, larger on lower part and middle of each 

 arm, very small at the tips ; tentacles rather thick, not extending 

 below the middle of the mantle, clubs terminal and small, crested 

 on each side, with numerous, small suckers. Length, 1-75 inch. 



Not figured. 



North of Shetland Isles. 



Dredged 60 to 100 fathoms. Seems to bear the same relation 

 to R. glaucopis that R. Oweirii and R. Panceri do to R. 

 macrosoma. 



R. HYATTI, Verrill. 



Body subcylindrical, usually broader posteriorly, in preserved 

 specimens, variable in form according to contraction, dorsal sur- 

 face covered with small, conical, scattered, whitish papillae, 

 which are also found on the upper and lateral surfaces of the 

 head and arms ; those around the eyes largest ; one on the mantle^ 

 in the median line, near the front edge is elongated. Fins 

 moderately large, nearly semicircular, lobed in front, the centre 

 of the fins being about the middle of the body. Siphon elon- 

 gated, conical, with small opening. Head depressed, more than 

 half the length of the body. Eyes large, lower eyelid more 

 prominent but not much thickened. Sessile arms short, united 

 at their bases by a short web, which is absent between the ven- 

 tral arms ; dorsals shortest ; third pair longest and largest ; 

 second and fourth pairs about equal in length. Suckers numer- 

 ous, subglobular, not very small ; near the base of the arms they 

 are biserial, there being usually four to six thus arranged in each 

 row, then they become more crowded, forming about four rows, 

 MI id very small and crowded towards the tips. Tentacles, in pre- 

 served specimens will extend back to posterior end of body, 

 smooth, somewhat triquetral, the sucker-bearing portion bordered 

 by a wide membrane on the upper, and a narrow one on the
