groove of the gladius is shallower than was illustrated by Appellof . 

 The modified suckers in the hectocotylized arm number about 20.

Station 4938 (near Sata-misaki, Kiushiu.) One female. Cat. 

 No. 332844, U.S.N.M. 



Station 4876 (Krusenstern Str.). Two specimens. Cat. No.

The mantle of these specimens measures 28-31 mm. in length. 

 They agree well with Hoyle's description except that the rim of 

 the inner cone runs straight posteriad, bordering the striated area 

 throughout and does not curve nor rise into any special wall-like 

 ridge.

Mantle roughly ovate in contour, a little narrower than half its 

 own dorsal length, pointed behind; dorsal margin protruding far 

 over the head in a triangular lobe about one-fifth the entire length. 

 Fins rather wide, about one-fifth as wide as the mantle, beginning at 

 some distance from the mantle margin and extending so far back- 

 ward that their bases come almost into contact with each other above 

 the rostum. Head a little wider than the mantle and one-third as 

 long. 



Arms subequal, the lateral pairs shorter than the others, which are 

 about one-third as long as the mantle. Suckers thickly set in four 

 series, except at the extreme base and tip of arms where they are 

 biserial. Horny ring smooth, but sometimes armed with very 

 short, broad, unequal teeth on the margin. 



Tentacles about as long as the mantle. Club somewhat flattened, 

 expanded, curved into a crescent-shape, occupying the distal sixth of 

 the tentacle. Suckers seemingly in five series, but numbering eight 

 in an oblique- transverse row; unequal, about three in a submedian 

 series being by far the largest, and larger than the arm-suckers. 

 Horny ring of these largest suckers armed with about 20 blunt or 

 square-cut, far separated teeth. 



Gladius very broad, thin, two and a half times as long as its own 

 maximum breadth, which is, in turn, three or four times as broad as 

 the thickness. Dorsal surface evenly convex, but its antero-mesial
