with the ears. Siphon situated in a shallow groove, united to the head 
by a pair of dorsal bridles, and furnished with a large internal valve. 
Six buccal aquiferous pores, and a pair of branchial pores, one on each 
side, between the bases of the third and fourth pairs of arms. Buccal 
membrane with seven elongated points, covered on their inner surfaces 
with small suckers; in the female with a special organ (Plate XXVI, 
fig. 4, s), below the beak, on the ventral side, for the attachment of the 
xparihnee tiie 
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 disappear- 
ance 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 proximal and distal por- 
tions; no connective suckers on the club or along the arm. Sucker- 
rings surrounded externally by a raised band.
