BUCCINUM UNDATUM. 95 



Didrlhutiov. — Jircent : deep water zone, west of Ireland, outer Hebrides, 

 Orkneys and Shetland ; Scandinavia (Jeffreys) ; Iceland (Torell). 

 Fossil : Butleyan Crag : Butley. 



Remarks.- — The Butley shell here represented, which appears to agree with that 

 figured by Jeffreys, is from the Sedgwick Museum at Cambridge. Forbes's original 

 specimen was brought from Zetland (Shetland), where he said it was frequently 

 found in very deep water ; Jeffreys states, on the authority of Carpenter and 

 Thomson, that it occurs to the north of the Hebrides in 500 to 050 fathoms. It 

 was described by Brown, though in error, under Gmelin's name of B. anglicauurn.

Dimensions. — L. -14 mm. B. 16 mm. 



Distribution. — Recent : Great Britain and Ireland, as far north as Aberdeen, 

 coralline zone, not common (Jeffreys) ; north coasts of France. 



Fossil: Waltonian Crag: Little Oakley. Butleyan: Butley (A. 

 Bell). 



Remarhs. — This shell is regarded as an abnormal variety of B. undatum. It 

 has but little resemblance to the type form of that species, having whorls nearly 

 flat, with indistinct or without longitudinal ribs, an acutely tapering and 

 elongated spire, and a different mouth. The shell originally described by 

 Broderip, now in the British Museum of Natural History, was found at Torquay : 

 the same variety has been obtained also in the north of France ; some years since 

 I picked it up on the beach at "Whitstable. I obtained a small specimen at Oakley, 

 quite perfect, but unfortunately it has been accidentally damaged. As it is 

 imperfect, as well as new to the Crag, I figure with it a Recent shell for the 

 convenience of future students. 



Mr. A. Bell informs me that this form may be met with occasionally in 

 Billingsgate market.
