A. E. Verriil—Marine Fauna of North America. 469 
Fins triangular, in advance of the middle of the body. Dorsal 
cartilage forming a median angle directed backward. Body 
flattened, soft, bordered bya membrane. Eyes covered by the 
integument. Web not reaching the tips of the arms, the edge 
concave in the intervals. Suckersin one row. Cirri absent be- 
tween the basal and terminal suckers. Right arm of second 
pair is altered, in the male, at the tip. 
Stauroteuthis syrtensis, sp. nov. 
8. Head broad, depressed, not very distinct from the body. 
Eyes large. Body elongated, flattened, soft or gelatinous, 
widest in the middle, narrowed but little forward, but decidedly 
tapered, back of the fins, to the flat, obtuse, or subtruncate tail. 
The sides of the head and of the body, forward of the fins, are 
bordered by a thin soft membrane, about half an inch wide. 
The fins are elongated, triangular, obtusely pointed, placed in 
advance of the middle of the body. Siphon elongated, slender, 
round, with a small terminal opening. Mantle edge so con- 
tracted and thickened around its base as to show scarcely any 
opening, and united to it dorsally. Arms long, slender, sub- 
equal, each united to the great web by a broad membrane devel- 
oped on its outer side, widest (about 15 inch) in the middle of 
the arm, while the edge of the web unites directly to the sides 
of the arms and runs along the free portion toward the very 
slender tip, as a border. This arrangement gives a swollen or 
campanulate form to the extended web. Edges of the web 
incurved between the arms, widest between the two lateral pairs 
of arms. The arms bear each fifty-five or more suckers, in a 
single row. Those in the middle region are wide apart (5 inch 
or more) with a pair of slender, thread-like cirri, about 1 inch 
ong, midway between them. ‘The cirri commence, in a rudi- 
mentary form, between the 5th and 6th suckers, on the dorsal 
arms, and between the 7th and 8th, on the ventral ones. They 
cease before the 23d sucker on the dorsal and lateral arms, 
and before the 22d on the ventral ones. Near the mouth, and 
tlings and streaks of dull brownish; inner surface of arms and 
web, toward the base, and membrane around the mouth, deep 
cluding lateral membrane); across eyes, 1°75; ac 
tail, 1:20; diameter of se 1; width of fins, at base, 120;
