 E. jacJcsonica Casey, Trans. St. Louis Acad., vol. 14, 1904, p. 106. Eocene. 

 He also refers to this group Mangilia meridionaHs O. Meyer. Upper Claibornian, 

 Cossmann, 1906, Essais, p. 223, svispends judgment on account of unfigured type. 



Eodriliia Casey, Trans. St. Louis Acad., vol. 14, 1904, p. 159, "Among the 

 typical species " are depyyis Conrad, lonsdalii Lea, surculopsis Gi'egorio, and 

 texana Courad (Casey). CossuKinn, 1906, Essais, p. 223, unites this with 

 Eopleurotoma. 



Eopleurotoma Cossmann, 1889, Cat. Illustr., p. 269. Type, PI. multicosiata 

 Deshayes. Eocene. Casey refers PI. nupera Conrad, gcmmata Conrad, hoening- 

 hausi Lea, and properugosa Gregorio to this group (1904). Cossmann, 1906, 

 Essais, p. 223, refers Eodriliia Casey, to this section.

 Eocene. Of the two species one is an Acteon or related Opisthobranch, the second

 Etallonia Oppel, 1861. 



Eubela Dall, 1889, Bull. Mus. Comp. Zool., vol. 18, pp. 102-6. Type, Daphnella 

 limacina Dall. 



EucheilodoB Gabb. Journ. Acad. Nat. Sci. Phila., vol. 4, 1860, p. 379. Type, 

 E. reticulata Gabb, Journ. Acad. Nat. Sci. Phila., vol. 4, pi. 667, fig. 18. Shell 

 much like Glyphostoma but attenuated in front, outer lip not expanded, the 

 aperture narrow and columella denticulate in the adult. Cossmann spells this 

 Euchilodon, ascribes the genus to Heilprin, cites E, crenocarinatus Heilprin, 

 1880, as type! Essais, vol. 3, p. 189, Apr., 1889. 



Eucithara Fischer, 1883, Man., p. 593. New name for Cythara Schumacher, 

 1817. not Klein ! Klein being nonbinomial this name is useless. The type- 

 mentioned by Fischer is Mangilia stromioides Eeeve.

 dicarinata Reeve, fide Cossmann. (Should be Pease, not Reeve.) Indopacific. 

 Shell with two very prominent carinae, beaded, with Clathurelloid aperture. 

 Cossmann names bicarinata as type. Boettger gives (1) tricarinata Reeve, and 

 (2) Mcnrinata Pease, but does not designate either as type. 



Exilia Conrad, Journ. Acad. Nat. Sci. Phila., ser. 2, vol. 4, p. 291, pi. 47, fig. 34, 

 1860. Type, E. pergracilis Conrad. Referred by Conrad to Pleurotomidae but

 Casey (ex A.ldrich), Trans. St. Louis Acad., vol. 14, 1904, p. 163. Cossmann,
