there are seven large teeth, the middle one longest, while to 
either side there is one nearly as large, with a smaller one each 
side of it.

This unique specimen was cast ashore, during a severe gale, 
near Cape Sable, N. S., several years ago, and was secured for 
the Provincial Museum at Halifax by J. Matthew Jones, Esq, 
It is preserved entire, in alcohol, and is still in good condition. 
Rossia Hyatti Verrill, sp. nov. 
Body subcylindrical, usually broader posteriorly, in preserved 
specimens, variable in form according to contraction, its dorsal 
surface covered with small, conical, scattered, whitish papilla, 
which are also found on the upper and lateral surfaces of the 
head and base of arms; those around the eyes largest; one on 
the mantle, in the median line, near the front edge, is elongated. 
Front border of mantle sinuous, slightly advancing in the mid- 
dle, above. Fins moderately large, nearly semi-circular, attached 
from the posterior end for about four-fifths the whole length, 
the front end having a small, rounded, free lobe. The distance 
from posterior junction of fin to end of body is less than that 
from anterior junction to edge of mantle, the center of the fin 
being at about the middle of the body. Siphon elongated, con- 
ical, with small opening. Head depressed, more than half the 
length of the body. Eyes large, the lower eyelid more prom- 
inent but not much thickened. Sessile arms short, united at 
their bases by a short web, which is absent between the ven 
arms; the dorsals are shortest; the third pair the longest and
