1898—1902. No. 20.] BRACHIOPODS AND MOLLUSCS. 35 
Cephalopoda. 
Rossia palpebrosa, Owen. 
(Fig. 9, a—b). 
Locality: 
Aug. 1. 1900. Bank at the entrance to Stordalen, Havnefjord, 8 m. Small stones. 
One specimen. 
The specimen, a female, has a total length of 30 mm. from the 
posterior end of the body to the base of the arms. Length of 1st pair 
of arms 26.5 mm. Umbrella is between 1st pair of arms 7 mm. high: 
its proportion to the length of the arms is thus 1:3.8. Between 4th pair 
of arms there is no web. Greatest breadth of body 18 mm. Breadth 
of head over eyes 17 mm. The head is thus only slightly narrower 
than the body. Length of body on the dorsal side 22 mm., on the 
ventral side 19 mm. Maximum length of fins 13 mm., length at base 
10 mm.,. maximum breadth 12 mm. Length of fins is thus 59 °/o of 
the length of body. — 
Body is posteriorly broadly rounded. On the dorsal side the 
mantle-edge forms a very obtuse angle, on the ventral side it is 
slightly incised. The well-developed siphon extends to the base of the 
4th pair of arms. Eyes not very prominent. Dorsal side of head and 
mantle are quite without papillae. Arms may be ranked in the follow- 
ing order according to length: 3, 4, 2, 1. Arm-suckers are arranged 
in two rows, though towards the tip they increase to apparently four 
rows. On the tentacular club the suckers are apparently six-rowed. 
Upper-row suckers of the base of the club are of about the same size 
as in the lower rows. Dorsal surface of mantle sac smooth and without 
papillae. Colour of the specimen preserved in alcohol is light whitish- 
red on the dorsal side with numerous dark chromatophores or spots. 
On the ventral side it is whitish with a few scattered dark spots. 
The specimen belong to the group palpebrosa glaucopts and may 
perhaps most properly be referred to rossia palpebrosa which OWEN 
has described. For on the dorsal side of the mantles sac we do not 
find the small whitish papillae that are so characteristic of the typical 
rossia glaucopis, Lovin. An additional reason for referring the speci- 
men to rossia palpebrosa seems to me to lie in the fact that it practi- 
cally quite agrees with the young female of this species which was 
found west of Spitzbergen by the Norse Norwegian Sea Expedition 
(station 363, 80° 03’ N. Lat. 8° 28’ E. Long. 475 m.). Dr. AppEeLLér states 
no doubt in “Teuthologische Beitrage” that this specimen is furnished 
on the back with small whitish papillae: still the papillae are smaller,
