110 BULLETIN OF THE 
sucker-pedicels yellowish white, with a few small brown chromatophores ; the 
outer portion of the fins is yellowish white and probably transparent when 
living. 
The sex of the single example was not determined. Possibly the remark- 
able suckers and pedicels on the distal half of the arms may be due to hecto- 
cotylization, peculiar to the male. In this example the dorsal arms are closely 
united together, to near the tips, and within the web the basal portion is much 
thickened and the suckers are crowded and partially concealed by the incurved 
margins of the arms, and by their facing strongly toward each other. This 
may also be a sexual character. 
Station 295, in 180 fathoms, off Barbados, Blake Expedition, 1878-79. 
This curious species has a striking general resemblance to Stoloteuthis leu- 
coptera V., from deep water off the New England coast. It is readily distin- 
guished by the free dorsal edge of the mantle, by the ventral shield projecting 
much farther forward, and by the remarkable form and structure of the distal 
sucker-pedicels and suckers. The fins are smaller, and the arms more slen- 
der. It is probable that the unique specimen is a male, and that some of the 
peculiar features of the arms and suckers may be only sexual. 
Rossia brachyura VeErRILL, sp. nov. 
Plate Ill. Fig. 2. 
A small species with a very short body, large fins, and very small suckers, in 
two rows on the basal part of the arms, but in four rows distally. 
Body unusually short, scarcely longer than broad, broadly rounded and 
somewhat emarginate posteriorly ; mantle-edge advancing in a broad obtuse 
lobe dorsally, extending farther forward with a slight median emargination 
ventrally. Fins very large and prominent, the insertion equal to about three 
quarters the length of the body, the outer margin thin and broadly rounded, 
the anterior lobe free, rounded, and projecting forward beyond the mantle- 
edge, the posterior margin also free and projecting back somewhat as a rounded 
lobe, reaching nearly to the end of the body. Eyes large, with the lower lid 
slightly thickened. Sessile arms rather long, subequal in length, the dorsal 
ones a little shorter than the others. The suckers are similar in size and 
arrangement on all the sessile arms; on the basal third they are arranged in 
two rows ; farther out they form four rows, which become crowded toward the 
tips. The suckers are very small, oblique, deep urceolate, with small aper- 
tures ; they decrease regularly from near the middle to the tips of the arms. 
Tentacular arms moderately long and stout ; club rather large, distinctly thick- 
ened, with a high dorsal keel ; suckers very numerous and small, campanulate, 
crowded in about 16 rows, decreasing gradually in size from the upper to the 
lower edge, where they become very minute. 
Color, in alcohol, pale purplish brown, with numerous small, unequal chro- 
matophores, beneath as well as above ; arms paler ; fins whitish.
