each side, between the bases of the 3d and 4th pairs of arras. Buc- 
cal membrane with seven elongated points, covered on their inner 
surfaces with small suckers ; in the female with a special organ (PI. 
XXIX, tig. 4, s ), below the beak, on the ventral side, for the attach- 
ment of the spermatophores. 
Sessile arms angular ; basal web rudimentary or none ; suckers in 
two rows, oblique, deep cup-shaped ; horny rings toothed on the 
broad side, and surrounded with a median ridge. Male with one of 
the ventral arms (usually the left) hectocotylized, near the tip, by an 
enlargement of the bases of the pedicels of the suckers and a decrease, 
or disappearance, of the cups. Tentacular arms long and strong, with 
an expanded club, provided with marginal membranes and a dorsal 
keel ; suckers, on the widest part, usually in four rows, those in the two 
central rows larger, broad urceolate ; smaller ones cover the proxi- 
mal and distal portions ; no connective suckers on the club or along 
the arm. 
Oviduct large, developed only on the left side. Nidamental 
glands large, in front of heart. Eggs in fusiform, gelatinous capsules, 
attached by one end, and usually radially united into large clusters.
