posite margin of the club appears to have borne several rows of small suckers, 
but this part is badly injured. 
À series of minute papillæ, apparently the remnants of suckers and rounded, 
alternating, connective tubercles (Fig. 1, e”), extends downward for more than 
half the length of the tentacular arm. The surface adjacent to them is, at 
first, crossed by transverse grooves or furrows ; but farther down the arm this 
modified surface is broader, and there may have been two or more series of 
suckers, which have been destroyed.

A specimen of this remarkable squid, in bad condition, was taken from the 
stomach of a fish trawled at Station 893, in 372 fathoms, about 100 miles 
south of Newport, R.I. It was accompanied by a specimen of Ommastrephes 
ulecebrosus, in a similar condition. Tt has lost its pen, its epidermis, and most 
of the horny hooks and sucker-rings ; the head is detached from the bod y, and 
the caudal fin is nearly destroyed; the eyelids are gone, but the eyeballs re- 
main. The description must, therefore, remain incomplete till other s specimens 
can be obtained.

Amer, Jour, Sci., XX. p. 393, for Nov. 1880 (published Oct, 25) ; Proc. Nat. Mus., 
III. p. 362, 1880. 
Body short, tapering to a small free tip ; fins small, united behind the tip of 
the body. Siphon united to the head by a pair of dorsal bands; not sunken in 
afurrow ; an internal valve. Mantle united to the sides of the siphon by sim- 
ple, linear, longitudinal, lateral ridges, and corresponding connective cartilages 
on the sides of the siphon, which are long-ovate, with a raised margin all 
around. A dorsal elongated connective cartilage on the neck, opposite the pen. 
A pair of subdorsal muscular commissures within the mantle cavity. Arms 
long, not webbed; suckers in two rows, largest on the middle of the lateral 
and dorsal arms ; homy rings of suckers smooth on most of the suckers, simply 
dentate on the distal ones. Eyes large, with rounded openings and thin, free 
lids. Buccal membrane simple, sac-like, with seven connective bridles, In- 
ternal anatomy of the female similar to that of Ommast rephes, Oviducts and 
nidamental glands symmetrically developed on the two sides, Pen broad, 
lanceolate, as in Loligo.
