3IO BULLETIN OF THE BUREAU OF FISHERIES. 



by a series of elevated transverse fleshy pads extending outwardly from the base of the pedicels; the latter 

 complication ceases at the proximal end of the club, but the pads and suckers continue in alternation, 

 although much reduced, down the stalk of the tentacle for over half its length ; the suckers of the ventral 

 row also are peculiarly differentiated, and perhaps worthy of note (though not to be distinguished in all 

 specimens) would seem two rows of five to eight extremely minute acetabula which sometimes parallel 

 the much larger suckers of the marginal row just below the large median hook; proximal to these the 

 suckers become more uniform and continue down the stalk much as on the opposite side, but more irreg- 

 ularly and without the interspersal of pads. Hardly any two published figures agree in their represen- 

 tation of the finer details of the tentacular arms, so that the numerous small discrepancies exhibited by 

 the Albatross specimens from these as well as from one another can hardly be regarded as significant 

 until more is known regarding their development and function. (PI. Lii, fig. 3, 4.) 



No hectocotylization observed and sexes not known to be otherwise outwardly differentiated. 



Gladius not examined, but for completeness a description of that of the Atlantic form as given by 

 Hoyle (i88g, p. 119) is appended: 



" The Gladius is narrow and linear anteriorly, but broader and lanceolate in the hinder two-thirds, 

 whilst it ends posteriorly in a hollow cup or cone, which has several diaphragms within it, and is not 

 covered outside and behind by a solid chitinous spine, as is the case with most, perhaps all, Onychoteu- 

 thids; at all events no species hitherto known has such a hollow cone. " 



Radula not examined; it is stated to include but five rows of teeth. 



Color in spirits very pale, the chromatophores exceedingly obscure. 



II. (PI. ui, fig. I, 2; pi. Lin; pi. Liv, fig. 1-4; pi. Lv, fig. I, 3-7.) At first sight ver>' different 

 from the foregoing appear two vastly larger examples from the region of Puget Sound which, while 

 somewhat dubiously referring them to the same species, I describe in corresponding detail in the suc- 

 ceeding paragraphs. 



Animal of moderate size, robust, powerful in appearance. Body loliginiform, subcylindrical, 

 somewhat compressed dorso-ventrally; slightly inflated between the anterior margin and the fins; 

 thence tapering rapidly at first, then more gradually, to an acute attenuate point between the fins. 

 Fins large, over half as long as the mantle, broad, rhomboid; obtusely angular in advance of the middle, 

 anterior lobes projecting well forward ; posterior margins continuous around the tip of the body, forming 

 an obtuse point. Anterior mantle margin evenly truncate above, projecting only very slightly in the 

 median line; broadly emarginate below, w-ith well-marked though somewhat rounded lateral angles. 

 Mantle coimectives the customar>' three in number, comprising a median elongate cartilage in the nuchal 

 region, and on either side of the funnel a wedge-shaped lateral one, having a bifurcate groove and corre- 

 sponding to a flattened ridge of similar shape on the inner surface of the mantle coincident with the 

 lateral angles of its margin (pi. LV, fig. S~6)- 



Head rather large, rounded above, flattened beneath. Eyes large; the lid openings large, with a 

 prominent slit-like sinus in front. Funnel broadly conical, rounded at the tip, supported above by a 

 pair of very wide thin bridles; opening wide, valved; funnel groove broad, rounded in outline, rather 

 shallow; funnel organ conspicuous, comprising a median lobate A-sbaped pad and two ovate lateral 

 ones (pi. tiv, fig. 4). 



.Sessile arms stout, of moderate length; slightly unequal, the dorsal and ventral pairs the shortest; 

 extremities attenuate. True umbrella wanting save between the second and third arms, where it is 

 very rudimentan,-; outer edges of third and fourth arms angled and keeled, and insignificant indications 

 of a similar membrane persistent on the second arms as well. Armature of ventral arms comprising four 

 rows of small suckers, their homy rings furnished with a few very slender acute teeth on the upper 

 margin; remaining arms agreeing in the possession of an entirely difi'erent arrangement; here two mar- 

 ginal rows of small suckers persist as on the ventral arms, but the two median rows are transformed into 

 stout hooks of a somewhat larger size than the suckers (pi. LV, fig. i, 3-4). 



Tentacles stout and rather short; the club broadly expanded and armed with a great multitude of 

 small basin-shaped suckers arrayed in numerous indistinct rows; homy rings with about twenty low 

 acute teeth (pi. liv, fig. 2); suckers largest near the middle of the club, but becoming extremely
