[197] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 407 



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 ,nm long, midway between them. The 

 cirri commence, in a rudimentary form, between the oth 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. Near 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 1218 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 iu front of the large glands, I took a large mature egg, covered 

 with 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 mm ; length, 6 mm . 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 

 Capt. Melvin Gilpatrick and crew, schooner " Polar Wave ", north latitude
