SIPHO SABINII. 183 



Var. minor, no v. Plate XXII, figs. 8 — 10. 



Dimensions. — L. 35 — 38 mm. B. 12 — 1^ mm. 



IHstribution. — Not known living. 



Fossil: Waltonian Crag : Little Oakley. Newbournian : Sutton, 

 Waldringfield, Foxhall, Felixstow. Butleyan : Batley, Sutton. 



Remarks. — This small but strong shell may be regarded, I think, as a dwarf and 

 slender variety of /S^. togatus. In form it resembles Prof. Gr. 0. Sars' var. aftenuata 

 of S. tortuosus, but that species has a depressed and regularly spiral apex, belonging 

 to the SipJionorbis group of Morch. In one of the specimens now figured, however 

 (fig. 10), the apex is distinctly bulbous. 



The present variety has been found at various localities in the Red Crag, though 

 not abundantly, but I do not know it from the Icenian.

Specific Characters. — Shell fusiform, not very solid ; whorls 7, less convex than 

 in <S. togatus, the last about three-fifths the total length ; spire regularly tapering ; 

 ornamented by numerous fine but well-marked spiral lines, equal to the spaces 

 between them, and extending to the base of the shell, crossed by exceedingly fine 

 and numeroiis lines of growth ; suture fairly deep ; mouth pyriform, slightly 

 notched inside by the impression of the spiral striae, ending in a narrow canal, 

 nearly straight or turning but slightly to the left ; outer lip thin ; inner lip forming 

 a narrow glaze closely adherent to the pillar, especially to the lower part of it. 



Dimensions. — L. 45 mm. B. 20 mm. 



Distribution. — Recent : North Atlantic, Davis Strait, Bafiin's Bay. 



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

 Pleistocene : Yoldia-claj, Norway. 



Remarks. — The specimen here figured is from the Reed Collection in the York 

 Museum and was found at Butley ; I have obtained half a dozen, somewhat worn, 

 from Oakley, which seem to be the same ; they correspond in form and sculpture 

 with those obtained during 1841 in Davis Strait, figured by Hancock as Fusus 

 Sabini, and during the cruise of H.M.S. " Triton " in 1882 between the Hebrides 

 and the Faroe Islands, described by Jeffreys imder the same name. Jeffreys states 

 that many living specimens were dredged there from depths of 608 and 640 

 fathoms.
