Probably Malea sp. indet. Maury, Bull. Amer. Pal., V, p. 113. 

 The figures are much reduced in size 



Pyrula pilsbryi B. Smith. 



Ficus papyralia Say, Gabb, Tr. Am. Philos. Soc, xv, p. 22.3. 

 Pyrula pilsbryi Smith, Proc. A. N. S. Phila. 1907, p. 213. 



Dr Smith has indicated the differential characters of this species. 



Psrrula carbasea Guppy. 



Ficus niississippiensis Gabb, Tr. Am. Philos. Soc, xv. Not of Conrad. 

 Pyrula carbasea Guppy, Q. J. Geol. Soc, xxii, 1876, p. 580, pi. 26, fig. 7. 



Although Guppy (Quart. Jour. Geol. Soc. xxxiii, 525) subsequent- 

 ly considered his species a synonym of Pyrula mississippiensis, he 

 probably did not actually compare specimens. The two species 

 agree closely in sculpture, the prominent revolving carinae being 

 slightly wider apart in P. carbasea than in P. mississippiensis. The 

 chief difference however is in the apical whorls. P. carbasea has only 

 one smooth, blunt uptilted embryonic whorl, while P. mississippien- 

 sis shows 2| or 3 regular smooth whorls. Dr. Burnett Smith has 

 illustrated the embryonic whorls of P. viississippiensis in Proc. A. 

 N. S. Phila., 1907, pi. XVII, fig. 5. 



One specimen in the Gabb collection, somewhat broken, measures: 



Length 29, diam. 13 mm. 



CYPRAEIDAE. 



Cypraea dominicensis Ciabb. Plate XXX, figs. 7, 8. 



Cypraca dominicensis Gabb, Tr. Am. Philos. Soc, xv, 1873, p. 235. 



The type has the form of C. liirida, being a little produced at both 



ends. There are 36 teeth on the outer lip, 29 on the inner. 



Length 39.5, lateral diam. 23.2, dorso-ventral diam. 19 mm. 



Type is no. 3003 A. N. S. P. 



Cypraea cinerea Gmelin. 



We refer one of the specimens included by Gabb in C. dominicen- 

 sis to this recent species. 



Cypraea Isabella Linne (patrespatrise Maiiry) 



Cypraea isabella L., Gabb, Tr. Am. Philos. Soc, xv, p. 235. 



Two specimens, which present no characters differing from the re- 

 cent shells. The larger one closely resembles a recent C. isabella 

 mexicana Stearns which we compared.
