Trans. Conn. Acad. , v, p. 349, pi. 38, fig. 1, pi. 46, fig. 6, June, 1881. 



Plate XXXV, figures 3, 4. 



Body short, broad, depressed, covered with a soft flabby integument, 

 which forms a loose border posteriorly; the front edge of the mantle ex- 

 tends forward dorsally into a prominent angle, but recedes very much ven- 

 trally. Fins very large and broad ; their anterior insertions being but 

 little back of the antero-lateral edge of the mantle, and their posterior 

 insertion close to the end of the body; the free borders of the fins are 

 thin and undulated, extending forward anteriorly beyond the edge of 

 the mantle, while the length, from base to outer edge, is about equal to 

 the breadth of the back between the bases of the fins. 



Head very large and broad, the width exceeding that of the body. 

 Eyes very large and prominent ; lower eyelids well developed but not 

 much thickened. Tentacles remarkably long and slender, in extension 

 about twice as long as the head and body together. The tentacular 

 club is somewhat thicker than the rest of the arm, rather long, narrow, 

 tapering to the tip, and covered with numerous minute, nearly globular, 

 slender pedicelled suckers, arranged in many rows. (Plate XXXV, fig. 

 4,«,&,c.) 



Sessile arms of moderate length ; rounded, very slender at tip ; the 

 1st, 2d, and 3d pairs are successively longer, while the ventral pair 

 is about equal to the 1st. Suckers rather small, nearly globular, ar- 

 ranged in two rows on all the arms (fig. 4, a). The suckers are all sim- 

 ilar, but are a little larger on the 3d pair of arms. The margin is sur-
