A, E. Verrill—North American Cephalopods. 221 
The dried sucker from the tentacular-arm appears to have been one 
of the largest, (Plate XVII, fig. 11). At the present time the trans- 
verse diameter of the ring, outside, is 28"; diameters of the edge, 24 
and 22™"; greatest breadth of the ring, including denticles, 9°5"™; 
least. breadth, on inner side, 6°5"", There are 48 marginal denticles, 
which are nearly the same in size and form, all around. They are 
narrow, triangular, acute, with the edges bevelled sharp, and with a 
central, thickened, triangular ridge on the outside. The ring is white, 
hard, smooth, and osseous in appearance. 
Of the other specimens enumerated in the first part of this paper, 
it is probable, judging from the proportions given, that Nos. 16, 18, 
and 19 also belonged to A. princeps. Nos. 18 and 19 appear to have 
been much larger than any of the examples of which portions have 
been preserved, and it was very unfortunate that the persons who 
secured them did not know their value, for they were both found 
within a few miles of the settlement at Little Bay Copper Mine, on 
the south arm of Notre Dame Bay, and could easily have been taken 
to St. John’s. 
Additional note on the suckers of Architeuthis Harvey. 
After printing the description of A. Harvey? some additional loose 
sucker-rims, from specimen No. 5, were found. Among these are 
some of the second or oblique kind, described as existing on the sessile 
arms of A. princeps. Therefore the remarks (on p. 201), in respect 
to the supposed absence of suckers on the former, will no longer hold 
good. These suckers of the second kind differ, however, from the 
corresponding ones of A. princeps in having, on the outer margin, 
more numerous, more slender and sharper teeth, which taper regu- 
larly from base to tip and are not so flattened. The larger of these 
sucker-rims (7) are 14°5™™ in diameter, across the base ; aperture, 9" ; 
height at back, 7""; in front, 2"; number of large denticles on 
outer margin, 10 to 14; the inner margin, except in the smaller ones, 
is either finely toothed or distinctly crenulated, and there are usually 
one or more irregular, broad, sharp, lobes or imperfect teeth on the 
lateral margins. The teeth of the outer margin are regular, strongly 
incurved, tapering from the base to the very sharp tips, and sharply 
bevelled on the edges. A smaller one (7) 11™™ across the base, and 
4°5 across the aperture, with height of back, 6", has five regular sharp 
teeth on the outer margin; two broad irregular, ones on each side, 
while the front edge is nearly entire. 
With these there were also some of the largest and least oblique
