view he is supported by Tryon and Posseit. However in “Monographie 
der Gattung Buccinum” Kogpett 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 grénlandicum. Amongst the material of the 
Fram Expedition there are forms which imperceptibly lead over from 
the typical buccinum grénlandicum to buccinum hancocki. In 
Frie.e’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 grén- 
landicum.

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.
