scattered along the tentacular-arms, as do our specimens. The rounded 
tubercles that always accompany these smooth-rimmed suckers are 
not mentioned, but doubtless they were also present. The beak was 
5 - 25 inches long and 3’5 broad, dark reddish brown, “with a large 
tooth in both margins of the inner mandible and a much smaller 
notch on each side of the outer mandible.” 
Mr. More believed this to be distinct from the Newfoundland 
species and referred it to A. dux , but his description agrees closely 
with the corresponding parts of A. Harveyi (No. 5) described by 
me, except in the relatively somewhat greater size of the sessile 
arms at base. In this respect, however, it is equalled or surpassed by 
our No. 14, and by others of the Newfoundland examples. This may 
also be only a peculiarity of the female. The measurements indicate 
a specimen intermediate in size between our Nos. 5 and 14, but the 
description is not sufficient to indicate with certainty to which of 
our species it was nearest related. A more detailed description, with 
figures of the suckers and odontophore, would probably settle this 
point. Mr. More supposed that the lateral suckers of the tentacular- 
club were larger in his example than in A. Harveyi , but that is not 
the case. 
A large cephalopod, referred doubtfully to Omrnastrephes , has been 
recorded from Japan and described by Dr. F. Hilgendorf.* It was 
taken on the east coast of Japan, N. lat. 35° to 36.° It had been 
split open, salted, and partly dried, and the viscera had been re- 
moved. The ends or clubs of the tentacles were also gone. In this 
condition it was on exhibition in Yedo. The following are the meas- 
urements given: Tip of tail to front edge of mantle, 1 86 cm (6 feet, 
1 inch) ; mantle to mouth, about 41 cm (1 foot, 5 inches) ; longer ses- 
sile arms, 197 cm (6'5 feet) ; from tip of tail to tip of sessile arms, 414 cni ; 
total expanse across outstretched tentacles, 600 CIU ; circumference of 
mantle (breadth as cut open), 130 cm ; length of caudal fin, 60 cm ; 
breadth of caudal fin in middle, 45 0 " 1 ; breadth of forward end of cau- 
dal fin, 28 crn ; diameter of posterior tip, l c,n ; tongue of funnel, 10 cm 
broad, 6 c,n long ; eye-opening, which was oblong-oval, without an ob- 
vious sinus, 19 um ; distance between eyes, 26 cm ; diameter of oval skin 
of lip, 12 cm by 8 CI11 ; breadth of sessile arms, ll cm ; of tentacles, 2 to 
3 c,n ; diameter of horny rings of suckers, on base, l‘5 cm ; height, 
0'7' nm ; number of denticles, 37.
