[ 197 ] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
arms bear each fifty-five or more suckers, in a single row. Those in the 
middle region are wide apart (12 mm or more) with a pair of slender, 
thread-like cirri, about 25 to 32 mm long, midway between them. The 
cirri commence, in a rudimentary form, between the 5th and 6th suckers, 
on the dorsal arms, and between the 7th and 8th, on the lateral and 
ventral ones. They cease before the 23d sucker on the dorsal and lateral 
arms, and before the 22d on the ventral ones, which bear each 14 pairs 
of cirri. Xear the mouth, and beyond the last cirri on the free portion 
of the arms, the suckers are more closely arranged. The jaws (figures 
4, 5) have short, pointed and but little incurved tips; the cutting edges 
of both jaws have regularly curved outlines. They are small, with a 
deep cavity. 
Beyond the last cirri on the dorsal arms there are 33 to 35 small 
suckers. The 2d arm on the right side appears to be imperfect. On 
this arm there are but 19 suckers beyond the last cirri; then follow 15, 
or more, minute, wartlike tubercles, extending to the tip. Color, in alco¬ 
hol, generally pale with irregular mottlings and streaks of dull brown¬ 
ish; inner surface of arms and web, toward the base, and membrane 
around the mouth, deep purplish-brown. 
Length from end of body to base of arms, 160 mm ; length to posterior 
base of fins, 63; to anterior base, 101; width across fins, 126; in advance 
of fins, 53 (not including lateral membrane); across eyes, 44; across end 
of tail, 30; diameter of eye, 30; width of fins, at base, 33; their length, 
44; length of arms, 330 to 355; portion beyond web, 63 to 76. Edge of 
extended web, between upper arms, about 101; between lateral arms, 
about 203; entire circumference of web, about 121S mm , but its exact ex¬ 
tent cannot be ascertained, because in our specimen the web between 
the ventral arms was badly torn. 
The oviduct is single and nearly median, its orifice being a little to 
the left of the median line. A large nidamental gland, consisting of a pos¬ 
terior, yellowish portion, and a much larger, round, dark brown, anterior 
portion, surrounds the oviduct; the portion behind these glands is thin, 
tubular, and contains large round ova. The anterior portion, in front 
of the glands, is large and much thickened, and terminates in a slightly 
bilabiate orifice, at the base of the siphon. From the portion of the 
oviduct in front of the large glands, I took a large mature egg, covered 
witji a hard, dark reddish brown case. 
The egg, seen endwise, has a broad, elliptical outline, and while the 
two ends are truncated and smoothish, the sides are ornamented with, 
numerous regular, roughened, elevated ribs. Greatest breadth of the 
egg, ll mm ; thickness, 7 ram ; length, 6 mra . The anal orifice is not raised 
on a distinct elevation. A small urethral papilla arises in front of the 
base of each gill. 
The only known example of this remarkable species was taken by
