Trans. Conn. Acad., v, p. 349,'pl. 38, fig. 1, pl. 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. 
Hyes 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 Le ae suckers, arranged in many rows. _ (Plate XXXV, fig. 
4, a,b,c.) 
_ Sessile arms of moderate length; rounded, very slender at tip; the 
Ist, 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-
