lOG BULLETIN OF THE 



The color is whitish, with rather large, well-separated, reddish brown chro- 

 matophores, both above aud below ; a large dark brown spot on the head above 

 each eye. 



The basal portion of the arms is destitute of suckers for some distance, then 

 there are two alternating rows of small hookfe along the middle ; these are fol- 

 lowed, distally, by two rows of small oblique suckers, having the horny rim of 

 the orifice armed on the outer or higher side with several long, slender, in- 

 curved teeth. 



The clubs are small, but distinctly enlarged and bordered by lateral mem- 

 branes ; in the middle portion there is a row of three or four lai;ger elongated 

 hooks, with a few smaller ones in the same row, and a row of suckers alter- 

 nating with the hooks ; outside of these, on each side, there is a row of mar- 

 ginal suckers ; at the tip there is a crowded cluster of minute suckers ; on the 

 wrist there is a small group of smooth suckers and tubercles. 



Length of the mantle, dorsally, 12 mm.; length of body and head, 14 mm.; 

 breadth of head, 5.5 mm.; breadth across fins, 12 mm.; from tip of tail to an- 

 terior lobe of fin, 7 mm.; tip of tail to origin of fin, 6 mm. ; length of tentacular 

 arms, 15 mm. 



The figure is from the type-specimen taken by the U. S. Fish Commission 

 oflf Martha's Vineyard, Station 1137, in 173 fathoms.

A fragment of an arm, from a rather large species of Ommastrephes or Stheno- 

 teuthis, was obtained by Commander J. E. Bartlett. It was brought up on the 

 sounding lead in 607 fathoms, 4j miles N. W. § W. of Sombrero Light, N. Lat. 

 18° 36', W. Long. 63° 32' 30" ; temperature of the bottom, 41°. 



This fragment is about 60 mm. long and 10 mm. broad at the larger end. 

 It is from the terminal portion of an arm of which the tip had been amputated 

 and healed. The suckers are rather large, on slender pedicles, which arise 

 from swollen elevations on the inner surface of the arm ; each margin of the 

 inner face is bordered by a moderately wide, thin, incurved membrane, which 

 is supported by well-marked transverse muscular ridges, which run out from 

 between the bases of the suckers. The suckers are obliquely attached, with 

 very oblique apertures ; the basal half of the cup is much smaller than the 

 outer portion, and is separated from it by a distinct constriction ; the distal 

 portion is obliquely cup-shaped, with the inner side much narrower than the 

 outer ; the margin is supported by a very broad, horny rim ; the outer edge of 

 the aperture is surrounded by a circle of 12 to 14 regular, close, very sharp 

 incurved teeth, _of which the median one is not distinctly larger than those 

 adjacent ; the inner half of the border is armed by numerous, very much
