 giving the animal a decidedly pot-bellied appearance. Anterior portion slightly constricted or concave 

 behind the edge, which is oblique, roundly excavated in front, and produced into a sharp point in the 

 median line behind. Back slightly keeled. Fins roxmded ovate on each side, not continuous around 

 the posterior extremity, which is produced into a conical point. Nuchal collar prominent, keeled in 

 the median line behind and on each side of the funnel; margin interrupted by the funnel, otherivise 

 entire. Head rather swollen. Eyes large, blue in life, with a black inner ring. Color yellowish white,

 Length of back, along dorsal keel, .7; do., on ventral surface, .5; max. diam., .43; width of back, .46; 

 width of fins, .66 transversely; .23 longitudinally. Length of head and collar on the dorsal line, .4; 

 total length, 2.2 in. Diameter of eye, .2 in. Cupules in two rows. Two hooks in the median line of 

 the extremities of each of the tentacular arms between the cupules. Mouth surroimded by a six-keeled

Habitat, caught in the towing net off San Francisco, Cal., in lat. 37° 22' and long. 140° 10', one 

 specimen, Dall, July 17, 1865. Coll. reg. No. 302. 



This pretty little species is doubtfully referred to the genus Onychoteuthis. It is well characterized 

 by its pot-bellied appearance and narrow rounded fins. The posterior part of the funnel is very 

 globose. " — (Dall, in American Jotunal of Conchology, vol. \ii, p. 96-97, 1872.) 



No furtlier information has been forthcoming in regard to this species since the appearance of the 

 original description as above quoted. It seems likely that the specimen in hand was immature, and 

 it has been suggested that if adult it might be found to possess affinities with Lestoteuihis kamlschatica 

 {Gonatus fabricii (Lichtenstein)), although this appears to me somewhat doubtful.

This species is here included because it has been reported from San Clemente Island, California, 

 on the authority of Cooper, by Carpenter, and from Oak Bay, British Columbia, by Taylor, but in each 

 case the determination seems at best a very doubtful one. 



The paper by Gabb containing the original description is reprinted in the appendix of the present 

 report. Gabb's specimen is said to have been taken off Cape Horn. 



Genus MOROTEDTHIS Verrill, 1881 



Moroteuthis Verrill, 1881. p. 298.

 Pfeffer, 1900, p. 156. 



Besides the peculiarities of the gladius as hereinafter mentioned, this genus has for lesser characters 

 the enormous size of its single species; the presence of about 36 hooks in two rows on the tentacle club; 

 and the very numerous pads and suckers of tlie fixing apparatus. Otlierwise tlie characters are very 

 much as in Onychoteuthis or Ancistroteuthis, to each of which Moroteuthis has at various times been 

 referred.

 of southwestern Alaska.
