fig. 4). They differ from this, however, in having more tumid whorls 
and a coarser sculpture. In this respect they more closely resemble 
fusus tortuosus from the Wellington Channel, which has been described 
and depicted by Reeve. However in Reeve’s species the aperture and 
basal canal is only half as long as the shell, while the Fram specimens 
are rather larger, 54.3 and 60.2 °/ of the shell’s height. In the smallest 
of the Fram specimens the aperture and basal canal is comparatively 
rather large, being 61.2°/o of the shell’s height. This specimen differs 
from the rest in having a straighter canal, and accordingly it should be 
referred to forma turrita (G. O. Sars, tab. 25, fig. 10). However it 
differs also from this form, if I may judge from the one I have seen 
in Mr. Frrete’s collection, in having more tumid whorls and a coarser 
sculpture. The spiral ribs in particular are coarser and more prominent. 
The specimens mentioned here are from Jones Sound, near the 
Wellington Channel, where ReEeve’s specimen was found, and they re- 
semble his specimen’ moreover in form and sculpture. There is there- 
fore every reason for believing that they belong to the same species. 
There being some doubt however, as has been more fully shown by 
FrietE in the General Report of the Norse Norwegian Sea Expedition 
(Mollusca I Buccinidae, 1882, p. 20), regarding the classification of 
Reeve’s species, I have preferred to follow the nomenclature proposed 
by FRIELE. . 
Buccinum undulatum, MOouer. 
Locality: 
July 30. 1898. Godhavn, about 6 m. One 40.5 mm. high typical specimen. 
Among the material of the next species there were several which 
are intermediate to buccinum undulatum. Perhaps therefore this species 
should more properly be described as a variety of buccinum grénlan- 
dicum.
