An account of the specimens of large Cephalopoda found in later times 
on the North-eastern Coast of America, is given by A. E. Verrill, -Tr. 
Conn. Ac. v. pp. 177-258, with plates, containing 14 instances ; 8 more 
are added by the same author in Am. J. Sci. (3) xix. pp. 284-287. 
Architeuthis harvcyi (Kent, as Megaloteuthis^ 1874) = monachus (Ver- 
rill, 1875), rmdi princcps (Verrill), N.E. Coast of America, comparatively 
described and figured by Verrill, Tr. Conn. Ac. v. pp. 210-217, & 223, 
pis. xvii.-xx. & pi. xxi. figs, i.-iii. ; Am. J. Sci. (3) xix. pp. 287 & 288, 
pis. xii. & xiii. ; also a note on the latter, body twenty feet long, in Nature, 
XX. p. 113. 
Megateuihus^ g.^n. Near Ommastrephes, but the eight true arms longer 
than the mantle, the two tentacular arms very slender, the pen twice as 
broad, and the terminal fin very small. M. martensi, sp. u., Japan, length 
from the edge of the mantle to the hinder extremity 186 centimetres. A 
model of it was placed in the Exhibition of Fishery at Berlin ; Hilgen- 
dorf, SB. nat. Fr. 1880, pp. 65-67. 
Some notes on giant Cuttlefish in New Zealand, 10-11 feet from the 
root of the arms to the tip of the tail, one with eight, another with ten 
arms, by Kirk, Tr. N. Z. Inst. xii. pp. 310-313. 
Sthenoteuthis, g. n., distinct from Ommastrephes by having, like Archi- 
teuthis, numerous small smooth-rimmed suckers alternating with tubercles 
on the proximal part of the club, for the mutual adhesion of the long ten- 
tacular arms ; lateral arms provided with very broad, thin marginal mem- 
branes ; caudal fin very broad. Architeuthis megaptera (YqyviW), Loligo 
hartrami (Lesueur), and probably also L. pteropus (Steenstrup), belong 
to this genus. Verrill, Tr. Conn. Ac. v. p. 223 [Feb. 1880], pi. xxi. 
figs. 1-9 : and Am. J. Sci. (3) xix. p. 288. [This is Ommastrephes, as 
defined by Steenstrup, supra. — Rec.] 
Thysanoteuthis rhombus (Troschel) is intermediate in anatomical features 
between Loligo and Ommastrephes, agreeing chiefly with the latter in the 
disposition of the intestinal tract, the sexual and urinary organs, the 
vena cava, and nidamental glands, and by the duplicity of the ovi- 
ducts, and with the former by the disposition of the heart and the arteria 
abdominalis and the transverse commissure of the ganglia stellata.
