[211] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
triangular and curved forward. On the larger suckers (Plate XLVI, 
figs. 1d, 1e) the outer teeth are obtuse, but on the distal ones they become 
more slender and acute. The margins of the suckers are surrounded 
with small, elongated scales. 
The buccal membrane is thin and much produced, with the angles 
little prominent; it is attached to the arms by eight thin, but wide, 
bridles, the two superior ones united together near their origin. The 
web between the arms is rudimentary but distinct. The pen (fig. 1a) is 
very unlike that of CO. Veranyi, as figured and described by D’Orbigny. 
It has a long, narrow shaft, of nearly uniform width, and a long poste- 
rior portion, a little wider than the shaft, corresponding in length to 
that of the caudal fin; at the commencement, this portion expands into 
narrow, free, incurved margins, but these unite quickly so as to form a 
long, narrow, angular, tubular portion, tapering to a very slender tip; 
this portion (fig. 1a’) has a distinct dorsal keel, with a groove each side 
of it, two dorsal angles, and a ventral angle along each side; the narrow 
Shaft has a dorsal keel, with the sides bent down abruptly, nearly at 
right angles, and a little incurved, so as to produce a squarish keel 
above, with a deep angular groove below, while the very narrow mar- 
gins bend outward abruptly (fig. 1a’); the shaft increases very slightly 
in width, to near the subacute anterior end, but preserves the same 
form, and there is no distinct dilation of the margin anteriorly, such as 
D’Orbigny figures in the pen of C. Veranyi, nor does the posterior por- 
tion resemble his figure, though if split open and flattened out it would 
resemble it more nearly. 
This specimen is an adult male, in the breeding condition, for its 
spermatophore-sac is much distended with spermatophores. The color 
is much like that of C. Veranyi. It is everywhere thickly specked with 
small, purplish brown chromatophores, except on the buccal membrane 
and the bases of the tentacular arms, where there are but few; the head, 
around the eyes, and the end of the siphon are darker; a row of very dis- 
tinct, rather large, round, dark purple spots runs along the inner surface 
of the ventral arms, just outside of, and alternating with, the upper row 
of suckers, which they about equal in size.

Brown’s Bank, off Nova Scotia, taken from the stomach of a cod (lot 
956). Presented to the United States Fish Commission by Capt. Wm. 
Dempsy and crew, of the schooner “Clara F. Friend,” June, 1881. 
The internal anatomy is somewhat peculiar in several respects, but will 
not be fully described in this place.
