SEARLBSIA PROXIMA. 145 



question has lost its apex; but Mr. Bell remembers it perfect, as indeed it was 

 when figured in Prof. Kendall's paper, to which reference should l)e made. 



Searlesia elegans, sp. no v. Plate XIV, fig. 18. 



Specific Characters. — Shell solid, conical, fusiform, whorls but little convex ; 

 regularly diminishing towards the apex ; ornamented by distinctly marked longi- 

 tudinal costffi, about 10 or 12 on the last whorl, crossed by fine spiral lines; 

 suture clearly defined ; mouth oval, ending in a short, open canal. 



Dimensions. — L. 20 mm. B. 10 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. 



Remarks. — The fossil here figured was found by me at Oakley some years ago, 

 but I have not been fortunate enough to meet with a second specimen. It has a 

 polished exterior, and the sculpture, though somewhat worn, is clearly defined. It has 

 hardly the appearance of a Crag shell, and may possibly belong to a group of Middle 

 Oligocene fossils, such as those described by Dr. Ravn in 1907,^ though Avith none 

 of them does it precisely correspond. I figure it provisionally as above. The 

 specimen is good enough to identify, though I have not been able to find the species 

 to which it should be referred. 



Mr. van der Gracht informs me that in the boulder-clay of Mecklenburg and 

 North Grermany there are erratics full of beautifully preserved fossils of Oligocene 

 age, derived, it is believed, from some submarine deposit the exact position of which 

 has not yet been ascertained but may be probably situated near the mouth of the 

 Baltic. He suggests that some of the extraneous fossils of the Crag may have 

 been derived from a more southerly and submarine extension of such beds. 



Searlesia proxima, sp. nov. Plate XIV, fig. 22. 



Specific Characters. — Shell fusiform, solid ; whorls decidedly convex ; orna- 

 mented by about twelve strong longitudinal ribs, not so wide as the interspaces 

 separating them, and by fine closely-set spiral lines which cross the ribs ; suture 

 well marked ; mouth oval, passing rather abruptly into a short, narrow and nearly 

 straight canal ; outer lip thin ; inner lip forming a slight glaze upon the pillar. 



Dimensions. — L. 25 mm. B. 12 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag ; Little Oakley. 



BemarJcs. — This shell, which has the polished appearance of that last described, 

 comes also from Oakley, and may be possibly, like it, derivative in the Crag.
