100 PLIOCENE MOLLUSCA. 



Distribution. — Recent : Lofoten Islands, North Cape, Greenland. 



Fossil : Waltonian Crag : Little Oakley. Unknown from the 

 Pleistocene of Norway. 



BemarJcs. — The shell described by Morch under this name has never been 

 figured, and some confusion has arisen in consequence. 



Posselt alludes to it {op. cit.) as something well known to Danish conchologists, 

 identifying it with B. cyaneum {? sericatum), Hancock, B. tenehrosum yar . horealis, 

 Middendorff, and B. oouui, Turton. 



Dr. 0yen has lately sent me a Recent specimen from Greenland identified as 

 typical of Morch's shell by Dr. A. Jensen, of the Zoological Museum at Copenhagen ; 

 this I have figured (PI. X, fig. 11), with a fossil from Oakley (fig. 12) with 

 Avhich it practically agrees ; the apparent difference between the two in the canal 

 is due to the fact that in the latter the lower part of the outer lip has been 

 broken off. 



Mr. Priele has figured as B. groenlandicwn var. sericata {op. cit.) a specimen 

 which closely corresponds with our Crag shell, and his figure has been reproduced 

 by Dr. Kobelt {op>. cit.) as B. sericatum. The former states, however, that it differs 

 from the B. sericatum of Hancock both in form and sculpture, suggesting it may 

 be a distinct species. MM. Dautzenberg and Fischer doubt, moreover, whether 

 Morch's shell is a variety of B. ciliatnm. 



Should this view be accepted hereafter I suggest it might be called B. Frielei. 

 Meanwhile I adopt Morch's name provisionally. In any case it seems probable that 

 Dr. 0yen's specimen, that of Mr. Friele and the Crag fossils are near varieties of 

 the same species. 



Since the above was wi'itten I have received another unfigured shell from Dr. 

 Jensen which he regards as the variety isecivv here referred to. It differs in 

 sculpture from Dr. 0yen's shell (fig. 11), agreeing more nearly in that respect with 

 the Oakley specimen (fig. 10) which appears to belong to the same group ; in 

 the latter also the outer lip is imperfect.
