Family CIRRHOTEUTHIDjE Keff. 
Kefferstein, in Bronn, Thier-Reich, iii, p. 1448, 1866. 
Body somewhat elongated, furnished with a short, thick tapering 
fin on each side, supported by an internal transverse cartilage. Man- 
tle extensively united to the head. No connective cartilages. Anns 
united together nearly to the tips by a broad umbrella-shaped mem- 
brane or web. Suckers in a single row, alternating with slender cirri. 
Stauroteuthis Verrill. 
Verrill, American Journal of Science, vol. xviii, p. 468, Dec., 1879. 
Allied to Cirrhoteuthis , but with the mantle united to the head all 
around, and to the dorsal side of the slender siphon, which it sur- 
rounds like a close collar, leaving only a very narrow opening around 
the base of the siphon, laterally and ventrally. Fins long-triangular, 
in advance of the middle of the body. Dorsal cartilage forming a 
median angle, directed backward. Body flattened, soft, bordered by 
a membrane. Eyes covered by the integument. Web not reaching 
the tips of the arms, the edge concave in the intervals. Suckers in 
one row, with a pair of slender cirri alternating with them along most 
of the arm. Cirri absent between the basal and terminal suckers. 
Stauroteuthis syrtensis Yerriii. 
Amer. Jour. Sci., vol. xviii, p. 468, Dec., 1879; xix, p. 294, pi. xvi, Apr., 1880.
