A. E. Verrill — North American Cephalopods. 
W. Long. 59", in 60 fathoms; another from 7 fathoms, off Miquelon I., 
(lot 372), was presented by Capt. C. D. Murphey and crew, of the 
schooner “Alice M. Williams.” Its relatively large eggs (PI. XXVII, 
fig. 9) are laid in August and September, in small clusters, slightly 
attached together, in the large oscules or cavities of several species of 
sponges. 
It is frequently associated with Octopus Bairdii V., and the 
following species. 
This species has a strong general i-esemblance to R. glaucopis 
Loven, as figured in the admirable work of G. O. Sars but the latter 
has shorter lateral arms, and the suckers of the sessile arms are in 
two rows, while they are four-rowed in our species.

Larger and relatively stouter than Rossia Hyatti , with the fins 
larger and placed farther forward, the rounded front edge of the large 
free lobe reaching nearly to the edge of the mantle. Head large 
and broad. Eyes very large. 
Sessile arms more slender and less unequal in size than in the 
preceding species, and with the suckers arranged in two regular rows 
throughout the whole length. Anterior edge of the mantle scarcely 
sinuous, advancing but little dorsally. Upper surface of the body 
and head nearly smooth, but in the larger specimens, especially 
the males, usually with a few very small whitish papillae, most 
numerous near the front edge of the mantle. Color, nearly as in the 
preceding species. 
The pen (Plate XLVI, figure 4) is small and thin, much shorter 
than the mantle. The shaft is narrow ; the blade is rather abruptly 
wider and rather shorter than the shaft ; its posterior portion is very 
thin, with the edge ill-defined. 
The males, when adult, can be easily distinguished from the 
females, by the larger size of the suckers along the middle of the two 
lateral pairs of arms (Plate XL VII, figure 4), and, to a less extent, 
of the ventral pair. These large suckers are oblong, with a groove 
or constriction around the middle, the part below the groove larger
