urements of this arm, as then preserved. It had contracted excessively 
in the alcohol, and was only 13 feet 1 inch in length (instead of 19 
. feet, its original length), the enlarged sucker-bearing portion being 27 - 
inches; the large suckers occupied 12 inches; the terminal part bear- 
ing small suckers, 9 inches; circumference of slender portion, 3.5 to 4.25 
inches; of largest part, 6 inches; breadth of face, among large suckers, 
2.5 inches; from face to back, 1.62 inches ; diameter of largest suckers 
outside, .75 of an inch; aperture, .63 of an inch. It will be evident 
from these measurements, when compared with those made while fresh 
and from the photograph, that the shrinkage had been chiefly in length, 
the thickness remaining about the same, but the suckers (which had 
lost their horny rims, and therefore their size and form) were ‘consid- 
erably smaller than the dimensions previously given. Comparing all 
these dimensions with those of the Logie. Bay specimen, and calculating 
the proportions as nearly as possible, it follows that this specimen was 
very nearly one-third larger than the latter, but the large suckers ap- 
pear to have been relatively smaller, for they were hardly one-twelfth 
larger than in the Logie Bay specimen. As the relative size of the large . 
suckers is a variable sexual character in certain species of squids, it is 
possible that the difference may be a sexual one in this case. 
A few of the horny rings from the small distal and lateral suckers 
(Plate IV, figs. 3, 3 a) were sent to me by Mr. Harvey. These agree 
well with the corresponding suckers of No. 5. 
To this species I formerly referred the jaws and’ two large suckers 
from the ‘club? of the tentacular arms of the Bonavista Bay specimen 
(No. 4, see p. 8). In form, size, and proportions the jaws resemble 
those of the specimen (No. 5) described above, so that the size of these 
two individuals must have been about thesame. These jaws had been 
dried, and were very badly broken when received, so that only part of 
their dimensions could be ascertained at first, but I have recently par- 
tially repaired them, so as to study them more fully (see table under A. 
princeps). The total length of the upper mandible was about 105"™; 
tip of beak to notch, 16™"; notch to end of proper cutting edge of alz, 
7o"". The lower mandible (Plate III, figs. 4, 4 a) shows both sides of 
the rostrum and ale. The notch and tooth are well marked, and the 
tooth in front of it is narrower and. much more elevated on one side 
than on the other. It is, therefore, quite possible that it belongs to A. 
princeps. The suckers (Plate IV, figs. 1, 1 a) had been dried, and 
have lost their true form, but the marginal rings are perfect, and only 
23.4" (.92 of an inch) in diameter, but though somewhat smaller than 
in the specimen just described, they have the same kind of denticula- 
tion around the margin. Their smaller size may indicate that the speci- 
men was a male, but they may not have been the largest of those on 
the tentacular arm. . 
To this species I also refer a young specimen (No. 24) which was : 
found floating at the ‘surface, at the Grand Bank of Newfoundland,
