 (0yen). 



BemarLs. — In the Norman collection at the British Museum (Natural History) 

 there are a number of Buccinums collected by Verkriizen from the Banks of New- 

 foundland which were regarded by him as different species, and named, but neither 

 figured nor fully described. As the specimens referred to were received by Canon 

 Norman from Verkriizen himself they may be taken to represent accurately the 

 type forms. They seem a distinct and interesting group ; Dr. Sparre Schneider, 

 our best authority on the subject, informs me they are unknown in Scandinavian 

 seas, or from any locality to the east of Newfoundland. 



Comparing them with Mr. E. A. Smith at tlie British Museum with some Crag- 

 fossils, we agreed that there were specimens among the latter which could not be 

 separated from Verkriizen's types. 



There appears to be some difference of opinion as to these Newfoundland 

 species, Avhich have been variously regarded as allied to B. vndatnm, B. gra'ii- 

 Jandiciim, B. terrse-nocse, B. Tottenii, or B. Amalise. 



The matter, however, seems one for northern conchologists ; 1 am content to 

 figure such of our fossils as may appear to correspond Avith Verkriizen's sliells, 

 the interesting point being that a group of mollusca said to be unknown from the 

 coasts of Great Britain or Scandinavia had their analogues in the North Sea in 

 Pliocene times. Dr. Sparre Schneider, having very kindly examined my specimens 

 of this group of Buccinums, reports that taken as a Avhole they bear a striking- 

 resemblance to those of the Recent fauna of Newfoundland. 



Speaking generally the spiral sculpture of these Newfoundland Buccinums is 

 fine and more or less inconspicuous. It seems possible that though forming a 

 group sufficiently distinct, some of them may 1)e regarded as varieties of one or 

 more central forms rather than as separate species. 



The Crag specimen of B. cariahile now figured is from Oakley ; it was identified 

 in the first case by Dr. 0yen as agreeing with one in the Museum at Christiania ; 

 the Recent shell here given is from the Norman collection.
