view In- i> .-npported by THYON and POSSELT. However in "Monographie 

 der (lathing Buccinum" KOMKLT seems most inclined to consider this 

 t'n rn i a- a true species. PFEFFER insists stronglv upon tliis in "Mollusken, 

 Kreh-e mid Echinodermen von Cumberland Sund". Still in spite of 

 lhe.-<' views I am inclined to consider Inicchiiutt liancocki to be a 

 variety of Imcchntni <ir<">nl(indicinn. Amongst the material of the 

 Fram Kxpedilion there are form- which imperceptibly lead over from 

 the tvpical hnccinnni gronlandicum to Imccinnni Ixincocki. In 

 FRIKI.E'S line collection of arctic hnccinidae. which I have been privi- 

 leged to inspect, there are several intermediate form.-. 



I append measurements of some specimens of the form liancocki: 



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

 head of the Gaasefjord, 8 m., there are egg-clusters of bncciniim griiu- 

 landicum.
