110 BULLETIN OF THE 



sucker-pedicels yellowish v/hite, with a few piuall biown chromatophores ; the 

 outer portion of the this is yellowish white and [)rubably 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 closelv 

 united together, to near the tips, and within the web the basal portion is much 

 thickened and the suckers are crowded and partially concealed l)y the incurved 

 margins of the arms, and by their facing strongly toward each other. This 

 may also be a sexual character. 



Station 295, in ISO Jathoms, off Barbados, Blake Expedition, 1878-79. 



This curious species has a striking general resemblance to Stoloteuthis leu- 

 coptera V., from deep water otf 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 prol)able 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 Verkill, sp. nov. 



Plate III. Fig. 3. 



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 distal ly. 



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 margui 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 bro\vn, with numerous small, unequal chro- 

 matophores, beneath as well as above ; arms paler ; fins whitish.
