A. E. Yerrill — North American Cephalopods. 221 



The dried sucker from the teiitaciilar-arin appears to have been one 

 of the hirgest, (Phxte XYII, 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*o"'"\ 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 

 scoured 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 Harveyi, 

 After printing the description of A. Harveyi 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 

 arras of ^4. 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 {i) 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 {j) ii™'" 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
