The generic affinities of this species must be regarded as still some- 
what doubtful, owing to the absence of the tentacular clubs, and most 
of the suckers of the sessile arms. The characters of the ‘pen;’ of 
the dentition, especially of the median teeth; of the nucltal frills; of 
the siphon; and of the cartilaginous facets, constituting the mantle 
fastenings, all indicate that it belongs in the family Teuthidw, near 
— Onyehoteuthis. But in this family there is a great diversity as to the 
arrangement of the hooks and suckers constituting the armature of the 
arms. Some of these combinations are as follows: 
TEUTHID&. 
Sessile arms with suckers only. 
Onychia.—Tentacular club with two central rows of hooks, rows of 
small suckers along each margin, and a cluster of suckers and tubercles 
on the ‘wrist.’ Sessile arms with smooth suckers. (Teleoteuthis V.) 
Onychoteuthis (typical)—Tentacular club with two rows of hooks, 
with an apical cluster of suckers, and with a cluster of suckers and 
tubercles on the wrist. (Plate XV, figs. 6, a-c.) Sessile arms with 
suckers in two rows. 
Ancistroteuthis (typical).—Two central rows of hooks, with proximal 
and apical suckers on the club, as in the last. Pen narrow, widest an- 
teriorly, with a long, terminal, hollow cone. 
Gonatus.—Tentacular club with one or two central median hooks, and 
with numerous, multiserial, small suckers, distally and laterally. Ses- 
sile arms with four rows of suckers, those of the two central rows larger, 
all serrate. 
Sessile arms with both suckers and hooks. 
Abralia.—Tentacular club with two rows of alternating hooks and 
suckers in the middle, and with a cluster of suckers on the wrist and 
two rows at the tip. Sessile arms with hooks on the basal portion, and 
two rows of small suckers toward the tips. Pen dilated in the middle, 
hooded at the tip. Buccal membrane with suckers.
