Several specimens. Guppy's figure is very poor, even for a Ja- 

 maica specimen. As a rule these are somewhat narrower than shells 

 from Santo Domingo. It seems very close to, if not identical with, 

 M. aurora Dall, from the Oligocene bed of the Chipola River; but 

 we have not been able to compare specimens of the latter. 



Mar^nella domingoensis Dall. 



Margindla domingoensis Dall, Proc. U. S. Nat. Mus. xix, 310, 1896. 



Four specimens we refer to this species. Dr. Dall writes: "This 



species is close to M. aurora Dall, from the Chipola marl, but has 



the tip of the spire less conspicuous and the aperture quite flexuous 



instead of nearly straight. " Length 24 mm., greatest diam. 14 mm. 



Marginella cercadensis Maury. 



Margindla chrysomelina Gabb, Tr. Ani. Philos. Soc. xv, 1873, p. 221. 



Four specimens, no. 3269. On two, traces of the spiral color lines 



may be seen. 



Marginella latissima Dall. 



Marginella laUssima Dall, Proc. U. S. Nat. Mus. xix, 1896, p. 308, pi. 29, 

 fig. 11. 



The specimens of this species from Santo Domingo represent 

 a great range of variation, but with many before us it seems im- 

 possible to assort them except by sizes. Gabb referred these doubt- 

 fully to M. apicina on the label, but he did not mention the species 

 in his work. 



Marginella amina Dall. 



Margindla amina Dall, Proc. U. S. Nat. Mus. xix, 1896, p. 309, pi. 29, fig. 15. 



Two specimens are labeled in Gabb's handwriting "M. antiqua 



Redfield", but they are not mentioned in his work. 



VOLUTIDAE. 



Lyria pulchella (Sowerby) 



Voluta pulchella Sowerby, Q. J. Geol. Soc, vi, 1849, p. 46, pi. 9, fig. 4. 



Lyria pulchella Sby., Gabb, Tr. Am. Philos. Soc, xv. p. 219. 



Lyria pulchella Sby., Dall, Bull. U. S. Nat. Mus. No. 90, p. 58, pi. 10, fig. 11. 



Sowerby has given a good figure of this species. In some speci- 

 mens the axial ribs become obsolete on the last whorl. 



Lyria mississippiensis (Conr.) of the Vicksburg Oligocene is a 

 closely related form. Dr. Dall has recorded L. pulchella from the 

 silex beds at Ballast Point, Florida. 



Lyria soror (Sowerby) Plate XXIV, flgs 11, 12. 



Voluta soror Sowerby, Q. J. Geol. Soc. vi, 1849, p. 46. 



The axial ribs are somewhat fiexuous and much more delicate
