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 / 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. 0. SARS, tab. 25, fig. 10). However it 

 differs also from this form, if I may judge from the one I have seen 

 in Mr. FRIELE'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 REEVE'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 

 FRIELE 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, MOLLER. 



Locality: 

 July 30. 1898. Godhavn, about b' 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 gronlan- 

 dicum. 



Buccinum gronlandicum, CHEMNITZ.

July 29. 1898. Egedesmindo. 

 Aug. 5. Upernivik, 826 m.
