r. j. l. curry on the miocene fossils of haiti. 519 



13. Natica mammillaris, Lam. 



Gabb considers JV. subclausa, Sow., to belong to this species. 



14. Natica phasianelloides, D'Orb. 



Gabb redescribes this species under the name of Amaura Guppy i, 

 but does not give his reason for disagreeing with my identification. 



15. SlGARETUS EXCENTRICUS, n. Sp. (PL XXIX. fig. 11.) 



Shell globose-depressed, adorned with many regular rounded 

 spiral ribs with much narrower threadlike interstices : spire de- 

 pressed ; whorls convex, the last much the largest ; aperture oval, 

 somewhat angulated posteriorly. 



A more globose shell with much more convex whorls than S. de- 

 pressus, Phil. ( = #. Jicdiotideus, D'Orb., =JS. LeacJiii, Sow., but not the 

 S. Jialiotideus of Linne. See Hanley, Ips. Linn. Conch, p. 390). 



16. Tueritella tornata, Guppy, G. J. vol. xxii. p. 580, pi. xxvi. 



fig. 12. 



17. Turritella plaxigyrata, Guppy, Proc. Scicnt. Assoc. Trinidad, 



1867, p. 169; Geol. Mag. 1874, p. 408, pi. xviii. fig. 5. 

 Gabb has recognized this species among the Haitian fossils ; and 

 his remarks upon it are appropriate. The figure in Geol. Mag. shows 

 only the general shape. 



18. Vermettjs papulosus, Guppy, G. J. vol. xxii. p. 292, pi. xvii. 



%. 3. 

 Gabb regards this as the end of the tubes of Petcdoconclms ; and 

 in this he may be right, though I do not feel completely satisfied on 

 the point. 



19. Petaloconchtjs sculpturatus, Lea ; P. domingensis, Sow. G. J. 

 vol. vi. p. 51, pi. x. fig. 9. 



20. Cerithium: uniseriale, Sow. G. J. vol. vi. p. 51. (PI. XXIX. 

 fig. 4.) 



This is a remarkable species ; and Sowerby's description applies 

 strictly to only one specimen. The species may be distinguished 

 generally by its peculiar ovate shape, also by the ascension of the 

 last whorl, near the aperture, halfway up to the suture, forming a 

 canal upon the body-whorl, between the angle of the aperture and 

 the callus of the inner lip, Avhich terminates in a broad and blunt 

 tooth. 



21. Cerithium obesum, Gabb, Trans. Amer. Phil. Soc. vol. xv. p. 237. 



(PI. XXIX. fig. 9.) 



22. Cerithium: plebeium, Sow. G. J. vol. vi. p. 51; Guppy, G. J. 

 vol. xxii. p. 290, pi. xvi. fig. 9. 



Near to G. ( Vertagus) gemmata, Hinds, Yoy. Sulph. pi. x. fig. 56.
