26 PROCEEDINGS OF THE ACADEMY OF [Jan., 



Lioderma lioderma Conrad, Proc. Acad. Nat. Sci., 1865, p. 184. 

 Liopeplum lioderma Dall, Trans. Wagner Free Inst. Sci., Ill, 73, 1890. 



The tyi^c^ of both Lioderma Conrad and Liopeplum Dall. 



Cancellaria eufaulensis Gabb, Jour. Acad. Nat. Sci., IV, 390, pi. 68, f. 8, 1860. 

 Cancellaria subalta Conrad, Am. Jour. Coucli., V, 100, pi. 9, f. 22, 1869. 

 Morea naticella (Gabb). 



Purpura (Morea) naticella Gabb, Jour. Acad. Nat. Sci., IV, 301, pi. 48, f. 

 15, 1860. 



This is probably the same as Morea cancellaria Conrad. 



Turbinopsis hilgardi Conrad, Jour. Acad. Nat. Sci., IV, 289, pi. 46, f. 29, 1860. 

 Turbinopsis depressa Gabb, Proc. Acad. Nat. Sci., 1861, p. 321. 



This is doubtfidly considered by Whitfield to be a synonym of T. 

 hilgardi. The specimens figured by him (pi. 12, figs. 7-9) represents 

 neither T. hilgardi Conr. nor T. depressa Gabb. 



Turbinopsis angulata Whitfield, Mon. U. S. Geol. Sur., XVIII, 101, pi. 12, figs. 17. 18, 1892. 



Type in the Academy's collection, not Rutgers College, as stated 

 by Wliitfield. 



Turbinopsis curta Whitfield, Mon. U. S. Geol. Sur., XVIII, 102, pi. 12, figs. 5, C, 1892. 

 Turbinopsis elevata Whitfield, Mon. U. S. Geol. Sur., XVIII, 102, pi. 12, figs. 10-14, 1892. 



Four specimens are referred to this species, three of which are figured. 

 I can find no character to separate three of these from T. curta. The 

 type should, therefore, be restricted to the specimen represented by 

 figs. 13 and 14, 



Turbinopsis plicata Whitfield, Mon. U. S. Geol. Sur., XVIII, 104, pi. 12, figs. 1, 2. 1892, 

 Turbinopsis lapidosa (Whitfield). 



Modulus lapidosa Whitfield, Mon. U. S. Geol. Sur., XVIII, 152, pi. 17, 

 figs. 6-8, 1892. 



This species is identical or close to Turhinopfiis depressa Gabb. 



Gyrotropis squamosus Gabb, Proc. Acad. Nat. Sei., 1876, 300, pi. 17, t. 5. 



Probably a Turbinopsis. 



Cithara crosswickensis Whitfield, Mon. U. S, Geol. Sur., XVIII. 107, pi. 13, figs. 7, 8, 1892. 

 Drillia georgiana Gabb, Proc. Acad. Nat. Sci., 1876, p. 280. 



CEPHALOPODA. 



Baculites ovatus Say, Am. Jour. Sci., II, 41, 1820 ; Morton. Jour. Acad. Nat. Sci., VI, 89, pi. 5, 



f. 6, 1828. 



The specimen described by Say and figured by Morton. 



Baculites compressus Say, Am. Jour. Sci., II, 41, 1820; Morton, Am. Jour. Sci., XXIII, 291, pi. 

 9, f. 1, 1833. 



The specimen figured by Morton. 



Baculites asper Morton, Am. Jour. Sci., XXIII, 291, 1830 ; Syn. Org. Rem., 43, pi. 1. figs. 12, 13, 

 pi. 13, f. 2, 1834.
