A. E. Verrill — North American Cephalopods. 287 
including teeth, 6 ’5 ; length of pedicels, 5 ; distance between pedicels, 
15“ The large suckers agree very well with those described and 
figured from the type-specimen (PI. XXI, fig. 9) ; this portion of the 
club had nine of these large suckers in each row ; their pedicels arise 
from the middle of deep squarish depressions, between which run 
thick transverse ridges, which bear the smaller marginal suckers 
toward their outer ends, and then support the marginal membrane. 
A part of the large suckers have retained their horny rings, but all 
the mai’ginal and small distal suckers have lost them. The horny 
rings of the large suckers (fig. 5a) are oblique, much higher on the 
outer than on the inner side ; the edge bears about 28 sharp, incurved, 
well-separated, unequal teeth ; of these the largest is at the middle of 
the outer edge ; another smaller one, but larger than its fellows, is at 
the middle of the inner edge; two others, in size similar to the last, 
occupy the middle of the lateral edges ; thus the edge is divided 
into four equal parts, by the four larger teeth, between which there 
are five or six smaller, very acute teeth, separated by spaces greater 
than their breadth. The horny rings are ambei’-brown, the teeth are 
golden yellow at tip. The distal portion of the club is compressed, 
with the face narrow and tapering, but with an elevated dorsal keel ; 
it bears four crowded rows of small, pedicelled suckers, the two 
rows on one side of the median line being composed of very much 
smaller suckers than the other two. At the very tip of the club 
there is a round cluster of small, smooth suckers, as in Architenthis. 
The buccal mass is 52 mm in length and 42 in diameter. A thick 
buccal membrane, covered with low, irregular verrucse, surrounds the 
jaws. The jaws are sharp and strong ; their exposed portions are 
black, the alfe reddish brown. The beak of the upper jaw is long, 
strongly incurved, acute, its cutting edge regularly curved, with a 
deep notch at its base, from which a well-defined groove runs down- 
ward. The lower jaw is sharp, its cutting edge is most concave near 
the tip, below which it is nearly straight, sides covered with fine 
radiating lines; basal notch broad, shallow, angular; beyond the 
notch there is a broad, low angular tooth. The surface of the fleshy 
palate is covered with low rounded verruca}. The odontophore is 
broad, with sharp, pale amber-colored teeth, which agree well with 
those of the original specimen (Plate XXI, figures 3-7) ; outside of 
the lateral teeth there is a narrow, raised, chitinous ridge, apparently 
not divisible into plates. 
Another specimen, consisting of the buccal mass and jaws, but 
without the odontophore, was presented to the U. .S. Fish Cotnmis-
