Calliteuthis Verrill. 
Amer. Journ. Sci., vol. xx, p. 393, for Nov., 1880 (published Oct. 25); Proc. Nat.Mus., vol. 
iii, p.362, 1880; Trans. Conn. Acad., vol. v, p. 295, Jan., 1881; Bulletin Mus. 
Comp. Zool., viii, p. Ill, March, 1881. 
Body short, tapering to a small, free tip. Fins small, united behind 
the tip of the body. Pen with a short narrow shaft and thin lanceolate 
blade, as in Loligo. Siphon not sunken in a furrow, but united to the 
head by a pair of dorsal bands; an internal valve. Mantle united to 
the sides of the siphon by simple, linear, longitudinal, lateral ridges, 
corresponding with connective cartilages on the sides of the siphon, 
which are long-ovate, with a raised margin all around. A dorsal, elon¬ 
gated, connective cartilage on the neck, opposite the pen. Arms long, 
not webbed. Suckers in two rows, largest on the middle of the lateral 
and dorsal arms; horny rings of suckers smooth on most of the suckers, 
simply dentate on the distal ones. Eyes large, with rounded openings 
and thin, free lids. IsTo nuchal frills or crests. Buccal membrane simple, 
sack-like, with seven connective bridles. Internal anatomy of the female 
similar to that of Ommastrephes. Oviducts and nidamental glands sym¬ 
metrically developed on the two sides. Oviducts opening in front of the 
bases of the gills, the openings simple, long, narrow, oblique. Two long, 
ligul’ate nidamental glands, with acute anterior ends, lie side by side and 
a little apart, on the middle of the visceral mass, behind and over the 
heart; each of these consists of two halves, folded together, and covered 
on the inner surface with fine transverse laminae; they open along the 
outer edge. 
This genus may, perhaps, belong to the Chiroteuthidcc.

Body rather short, tapering backward, subacute posteriorly; front 
edge of mantle advancing somewhat in the middle and forming an ob¬
