[ 105 ] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
lateral denticles of the median and inner lateral teeth are relatively 
shorter, and these, with some other differences, render it doubtful 
whether this beak actually belongs to that species. The odontophore is 
4 mm broad ; the teeth are all sharp, rather slender, pointed, and pale 
amber-color. A slight, smoothish, marginal rjdge borders the dentiger¬ 
ous zone on each side, but is scarcely divided into distinct plates. The 
median teeth have three sharp, rather slender denticles, the median 
about a third longer than the lateral; the inner lateral teeth have a 
long point, with the acute outer denticle much shorter; the teeth of 
both outer rows are long, considerably incurved, acute, the outer ones 
the more slender. 
Several additional specimens of this species have recently been re¬ 
ceived. The most important of these consists of the tentacular club 
and the pharynx, with the jaws and odontophore complete (Plate XVII, 
fig. 1). These are from a specimen of which the head and arms were 
found in the mouth of a codfish on the eastern part of George’s Bank, 
by Manuel D. Mitchel, and were by him presented to the United States 
Fish Commission. The portions of the specimen not saved were used as 
bait for cod. The arms were described as 18 inches long. 
The part of the tentacular club in my possession, which does not in¬ 
clude the proximal portion, is 175 mm long, I7 mm broad in the middle ; 
the distal portion, beyond the large suckers, is 62 mm long; breadth of its 
sucker-bearing face, 8 mm ; from front to back, including width of dorsal 
keel, but not the suckers, 18 mm ; diameter of largest suckers, 12 mm ; of 
horny rings, ll mm ; of aperture, 8 mm ; hight of horny ring, outer side, 
including teeth, fi.d 111111 ; length of pedicels, 5“™ ; distance between pedi¬ 
cels, 15 mm . The large suckers agree very well with those described and 
figured from the type-specimen (Plate XVI, 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 to¬ 
ward their outer ends, and then support the marginal membrane. A 
part of the large suckers have retained their horny rings, but all the 
marginal and small distal suckers have lost them. The horny rings 
of the large suckers (fig. 10 ) 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 homy rings are amber-brown, the teeth are golden yel¬ 
low 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, pediceled suckers, the two rows on one side of 
the median line being composed of very much smaller suckers than the
