obtusely corneal than E. Huzardi, with sculpture closer and apex 

 nearly central. 



6. oboyata (pi. x. f. 6), A. Adams. — Elongata, obovata, de- 

 presso-conica, testacea, vertice subcentrali, retrorsum inclinato, 

 costellis radiantibus, imbricato-asperis, et liris elevatis, concen- 

 tricis, cancellata ; apertura postice rotundata, antice angustata, 

 margine creno-denticulato, antice profunde iuciso. Obs. Sharply 

 cancellated. The slit very long. 



7. clatiirata (f. 54), Pease. — Depressa, postice lata, antice 

 angustata ; interstitiis foveolatis et costellis concentricis cancellata ; 

 apice versus rnarginem posticurn posita ; costis magnis, rotundis. 

 Obs. The ribs, particularly the six or eight posterior ones, are 

 large and rounded, the interstices deeply pitted. 



S. acoleata (f. 58), A. Adams. — Elongato-ovalis, depressa, 

 rufescens, vertice subpostico, retrorsum inclinato, costis radianti- 

 bus, aculeato-asperis, prominentibus, interstitiis valde clatbratis ; 

 aperturse margine denticulato, antice fissurato, fissura profunda. 

 Obs. Not so enlarged posteriorly as E. obovata. 



9. eximia (f. 03), A. Adams. — Elongato-ovalis, valde de- 

 pressa, alba, subpellucida, vertice postico retrorsum inclinato, 

 costis radiantibus, distantibus, prominentibus, imbricato-nodosis, 

 interstitiis liris transversis et longitudinalibus late cancellata; 

 tota superficie linealis radiantibus et concentricis pulcherrime de- 

 cussata ; aperturtc margine denticulato, antice profunde iuciso. 

 Obs. Eemarkable for the large regular pits between the ribs. 



10. elongata (f. 33), Pli'd. — Oblongo-ovata, subdepressa, 

 costis radiantibus, nodulosis, altematis et lineis elevatis crebris 

 cancellata, interstitiis tenuissimis, nitentibus ; apice versus rnar- 

 ginem posticum recurvo. Obs. The shell here described seems 

 best to agree with Philippi's figure. 



11. micans (f. 60), A. Adams. — Elonpato-ovalis, pallide fusca, 

 nitida, vertice postice declinato, costellis radiantibus et lineis 

 elevatis transversis, regulariter cancellata ; cancelli quadra ti ; aper- 

 tura? margine denticulato, incisura, magna et longa. Obs. 

 Scarcely differing from E. elongata, which also has the interstices 

 deep and shining, excepting in being a much more conical shell. 



12. concinna (f. 34, 39, 40), A. Adams. — Ovato-depressa, 

 albida, vertice postico, ad rnarginem declinato, costis sulcosis, 

 distantibus, radiantibus (circa 12), interstitiis lineis longitudina- 

 libus, et transversis, concinne decussatis; aperlurse margine den- 

 tato, antice profunde inciso.
