BULIvBTIN OB THE BUREAU OP FISHERIES. 
Head very large, due to the large rounded eyes; broader than the body; flattened above, much 
excavated beneath. Eyes prominent, with large white pupils and a very deep ventral lid fold. Fun- 
nel very stout and thick; flattened; outline blimtly conical; extremity rounded; aperture small. 
Sessile arms short, stout, thick; tmequal, the order of length 3, 4, 2, i; dorsal pair shortest, third 
pair longest,^ but the ventral almost as long as the third and even longer if measured along the cleft 
separating their inner ventral margins; connected at base by a fleshy umbrella, best developed between 
the dorsal arms, between these and the second pair, and between the third pair and the ventral pair; 
between the second and third arms the web is very short, and is totally lacking between the arms of the 
ventral pair, which are divided from one another by a deep cleft extending as far back as the tip of the 
funnel; second arms rounded, the remainder with a distinct 
keel along their outer margins distal to the webbed portion. 
Suckers small, spherical, oblique; in two rows extending 
nearly or quite to the tips of the third arms, but leaving the 
final distal extremities of all the other arms bare; this cir- 
cumstance becomes especially conspicuous in the case of the 
second pair, where the distal portion of the arm is not only 
devoid of suckers, but is minutely ridged transversely and 
exhibits a strong tendency to recoil upon itself (pi. u, fig. 5); 
homy rings of suckers smooth. 
Tentacles rather short, stout, angled, slightly tapering, 
with a flattened and somewhat grooved out inner surface. 
Club small, of considerably less diameter than the stalk; 
inner aspect with a velvety appearance, due to the great 
multitude of exceedingly minute suckers with which it is 
armed (pi. L, fig. 3). 
Surface everywhere smooth. 
Color of the living animal imknown; in alcohol a brownish 
buff; fins and arm tips unmarked; dorsum and head heavily 
dotted and clouded with the blackish chromatophores which 
appear as open reticulations about the bases of the fins; 
ventral surface of mantle less densely pigmented, except for 
a shield-shaped area occupying the ventral lobe and extend- 
ing back therefrom, over which the chromatophores are very 
numerous and distinct, being apparently of two main sizes, 
somewhat as noted in the case of Stoloteuthis iris; the mar- 
ginal delimitation of this area is by no means so distinct and 
conspicuous as the corresponding region of Stoloteuthis and was hence overlooked by the artist when 
the first drawings were made (pi. L, fig. 7). Chromatophores appear also upon the ventral aspect of the 
head and funnel, even extending upon the dorsal surface of the latter, but are not to be distinguished 
upon the tentacles. 
Gladius apparently wanting.
