view he is supported by TRYON and POSSELT. However in "Monographic 

 der Gattung Buccinum" KOBELT seems most inclined to consider this 

 form as a true species. PFEFFER insists strongly upon this in "Mollusken, 

 Krebse und Echinodermen von Cumberland Sund". Still in spite of 

 these views I am inclined to consider buccinum hancocki to be a 

 variety of buccinum gronlandicum. Amongst the material of the 

 Fram Expedition there are forms which imperceptibly lead over from 

 the typical buccinum gronlandicum to buccinum hancocki. In 

 FRIELE'S fine collection of arctic buccinidae, which I have been privi- 

 leged to inspect, there are several intermediate forms. 



I append measurements of some specimens of the form hancocki: 



From the winter harbour, Havnefjord, about 40 m., and from the 

 head of the Gaasefjord, 8 m., there are egg-clusters of buccinum gron- 

 landicum. 



Buccinum hydrophanum, HANCOCK. 



Locality: 



July 29. 1898. The winter harbour, Havnefjord, 12 m. 



July 21. 1900. , about 60 m. Small stones and 



lithothamnia. 



July 25. , about 20 in. Rocks and stones. 



Aug. 1. 1900. Off the entrance to Stordalen, Havnefjord, up to 20 m. Small 



stones with some clay. 



Aug. 1. , 10 50m. Small stones. 



Aug. 3. Fosheims Peak and the valley on the west side of Havnefjord, 



440 m. Small stones. 



Sept. 19. Off Forvisningsdalen, Gaasefjord, 4 40 m. Clay with small stones. 

 Sept. 20. The head of the Gaasefjord, 640 m. Clay with small stones. 

 July 8. 1901. Renbugten, about 20 m. 

 July 12. Bay near Landsend, about 35 m. 

 Aug. 2. The head of the Gaasefjord, about 40 m 



Aug. 16. , about 14 m. 



Aug. 30. , about 8 m. 



July 17. 1902. East of the large glacier, North Devon. 



At the head of the Gaasefjord this species seems to have been 

 abundant, but at other localities it would appear on the other hand to 

 have been scarce.
