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.

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 rouuded openings 

 and thin, free lids. . No 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, 

 ligulate 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 Chiroteuthidce. 



Calliteuthis reversa Verrill.
