APORRITATS SERRESIANUS. 437 



recent or fossil, than A. pes-pelicani, can Wo easily distinguished from it. Wood 

 describes an immature specimen from the Coralline Crag. I have figured a 

 recent and perfect shell from Bergen for the purpose of comparison. I have 

 not noticed it at Oakley but probably it may be discovered at some other Crag 

 localities if specially looked for. It was obtained by the Valorous Expedition in 

 Davis Strait. The var. Macandrese has been found in the Scaldisien of Antwerp. 



Mr. Marshall states (op. cit.) that A. Serresianus has been dredged on the 

 W. and S.W. coasts of Ireland, off the Shetlands (85—12301), in the Shetland- 

 Faroe Channel, in the North Sea to the N.E. of Aberdeen and in the English 

 Channel — in the latter locality from 358 to 090 fathoms (' Porcupine ' Expedition).

Varietal Characters. — Smaller than the type and more delicately sculptured, 

 the spire is shorter and less tapering, the whorls are fewer and rounded rather 

 than angulate. 



Dimensions. — L. 24 mm. B. 8 mm. 



Distribution. — Recent: Shetlands, Faroe-Shetland Channel, west Coast of 

 Norway, Lofoten Islands, west Greenland, Bay of Biscay. 

 Fossil : Scaldisien : Antwerp. 



Pleistocene : Ficarazzi. 



Remarks. — Originally described by Jeffreys as a distinct species, it has since 

 been regarded by Prof. Kobelt as a northern and deep sea variety of A. Serresianus, 

 from which it differs but little, except in size and its less prominent sculpture, 

 apparently bearing a similar relation to that species as the var. minor of 

 A. pes-pelicani does to the normal form. Mr. Marshall states that as a recent 

 British shell it is confined to a limited area in the Shetland seas. 



The specimen now figured is from the Scaldisien of Antwerp. I have not 

 found it at Oakley, but it should be looked for in the East Anglian Crag. The 

 Marchese di Monterosato, who regards it as a distinct variety, reports it from the 

 Sicilian Pleistocene of Ficarazzi (fide Kobelt).
