Both specimens belong to the variety expansa, G.O. Sars. The 
spiral striation in both is but slightly developed. The groove on the 
columella in the specimen from the winter harbour is deeper, narrower 
and shorter than in the other specimen. ‘The largest specimen measures: 
Long. 19 mm., Lat. 15.5 mm. 
A specimen found by the Nares Polar Expedition in the stomach 
of a phoca barbata near Franklin Pierce Bay, Grinnell Land, had a 
length of 21mm. At Spitzbergen the species attains a length of 23 mm. 
Onchidiopsis groenlandica, BERGH. 
Locality: 
July 26. 1900. The west side of the entrance to Stordalen, Havnefjord, 20m. Clay. 
A very contracted specimen. 
Natica, lunatia, groenlandica, BEck. 
Locality: 
July 8. 1901. Renbugten, about 20 m. An empty shell of the typical form. Alt. 
26 mm., Lat. 95.5 mm. 
Aug. 16. , The head of the Gaasefjord, about 14 m. A rather young specimen 
(Alt. 14.5 mm., Lat. 12 mm.) belonging to the form pallida, Broprrie 
& Sowersy. The shell is pale yellowish horn-colour, spiral sculp- 
ture extremely fine, operculum yellowish-brown and without calca- 
reous partition. 
Natica clausa, Broperir & SowERBY. 
Locality: 
July 15. 1902. Off Havhestfjeld, North Devon. One specimen belonging to the 
typical form (natica affinis, Gme.in). 
Alt. 23.5 mm., Lat. 21.5 mm. Spiral sculpture wanting. 
Bela harpularia, Covutuovy. 
Locality: 
July 26. 1900. The entrance to Stordalen, Havnefjord. A rather worn empty shell, 
10.5 mm. 
Both in outward appearance and in sculpture the specimen exactly 
corresponds with the West Greenland and North American form of bela 
harpularia of which I have had two specimens from Georger Bank for 
purposes of comparison. Therefore although the specimen is not in a 
very good state of preservation it must undoubtedly be referred to this 
species. It differs from the Greenland bela woodiana, which it closely 
resembles, in having a more slender form, less prominent carina, fewer 
ribs —- I counted 17 ribs on the last whorl, while according to PosseLt 
bela woodiana has 20—25 ribs — and a finer spiral sculpture.
