SKAKLESIA LUNDGRKNIT. 143 



Searlesia Oyeni, sp. nov. Plate XIV, figs. 10, 20. 



Specific Chdrdrfc m.—'^hvW solid, fusiform; whorls 0, convex, the last five- 

 eighths the total length ; ornamented by strong, prominent and rather distant 

 longitudinal costse, and hj close-set spiral ridges, which l^ecome more or less 

 obsolete below the suture ; spire elongate, regularly diminishing in size, with a 

 blunt point ; suture deep ; mouth oval, angulate above; outer lip regularly curved, 

 l)ut little expanded, thickened by the labial rib, not toothed within ; canal short, 

 narrow, turning slightly to the left. 



Dimensions. — L. 17 — 24 mm. B. 7 — 10 mm. 



Disfribution. — Not known living. 



Fossil : Isle of Man. 



Remarks. — The Manx fossils from the Jermyn Street Museum here figured 

 appear to be something new ; I have been unable to find anything to which I can 

 refer them, and they are unknown, either Recent or fossil, to the experts to whom 

 they have been submitted. At Jermyn Street they are labelled Fnsits Fovhesi, but 

 I doubt whether they have any connection with that species, the outer Hjd of which, 

 moreover, is internally toothed. They seem allied rather to S. Bjornsoni, but 

 differ from the latter in form and sculpture, and in the smaller number of the 

 longitudinal costse. I name this shell after my friend Dr. oyen, of Christiania, 

 whose assistance with the Scandinavian species of mollusca I very gratefully 

 acknowledge.

Specific Characters. — Shell smaller than 8. costifer, ovate, fusiform, solid; 

 whorls 5 or G, convex, regularly diminishing in size, the last more than two- 

 thirds the total length ; ornamented by 10 to 12 strong longitudinal costse, not 

 so wide as the spaces between them, which extend nearly to the base of the shell, 

 and by fine, regularly sculptured spiral lines which cross the longitudinal ribs, 

 sometimes becoming tuberculate at the point of intersection ; suture distinctly 

 marked ; spire short, ending in a blunt point ; mouth ovate, angulate above ; 

 outer lip not thickened or denticulate within ; inner lip closely adherent to the 

 pillar ; canal short, rather narrow, turning slightly to the left. 



Dimensions. — L. 30 mm. B. 16 mm. 



Distribution. — Not known living.
