A. E. Verrill — North American Cephalopoda. 
die; these have lost their horny claws; series of minute, slender-pedi- 
celled suckers run along the club, either side of the median line, and 
beyond the large hooks these rows unite and entirely cover the face of 
the distal third of the club (fig. 1, d), there forming about eight rows ; 
at the tip there is a circular group of minute suckers (cl ') ; toward the 
base of the club the lower side is expanded and bears a row of five 
peculiar suckers (fig. 1, e), having a marginal series of slender, 
minute, incurved spinules ; these suckers have very thick basal pro- 
cesses, which are appressed and directed toward the central line of the 
club, bearing the suckers on their inner ends, attached by short pedi- 
cels ; round connective tubercles alternate with these suckers, in the 
same row ; beyond these there is a triangular marginal group of 
slender-pedicelled suckers (c), of about the same size ; other rows of 
minute pedicelled suckers (or hooks) occupied the sub-median area, 
between the marginal ones and the central line, which is indicated by 
a strong white cord. The opposite margin of the club appears to have 
borne several rows of small suckers, but this part is badly injured. A 
band of minute papillae (e'), apparently the l-emnants of suckers and 
alternating connective tubercles, extends downward for more than 
half the length of the tentacular-arm ; at first this band is like a 
continuation of the connective suckers and tubercles on the margin 
of the club, and the papillae are apparently in a single row, while the 
surface near them is crossed by fine transverse grooves or furrows ; 
but farther down the arms there may have been two or more rows of 
suckers, which have been destroyed. 
The beak (fig. 1 f) is somewhat compressed, with very acute man- 
dibles. The upper mandible has the point long and regularly 
incurved, with the cutting edge regularly arched, without a basal 
notch, and forming, with the anterior edge, an obtuse angle. Lower 
mandible, with a strongly incurved tip and regularly concave cutting 
edge, having no basal notch, and only a slight tooth on the anterior 
border, which forms a very obtuse angle with the cutting edge. 
Color mostly gone, but where still remaining, as on the back of 
the tentacular club, it consists of minute purple chromatophores ; 
inner surface of sessile arms purplish brown.
