form which was originally called ritchiei. The localities of the fossil and 

 recent form are nearly abreast of each other, though some distance apart. 



Cerion (Strophtops) glans Kiister. 



Pupa glans Kiister, 1848, Conch. Cab. ed. II, p. 74, pi. 11, figs. 1, 2. 



Cerion {StropMops) glans Pilsbry, 1902, Man. Conch., XIV, p. 253, pi. 43, fig. 56. 



Fossil at Station 14, Andros Group, with the last species: also by 

 Agassiz on Andros and Great Stirrup Cay. Living on Andros, New Provi- 

 dence, and their associated cays and islets. 



This agrees with the figure cited from the Manual of Conchology. 



Cerion (Strophiops) blandi Pilsbry and Yanatta. 



Cerion hlandi Pilsbry and Vanatta, 1896, Proc. Acad. Nat. Sci. Phila., p. 334, pi. 11, 

 fig. 7; Man. Conch., XIV, p. 263, pi. 44, fig. 81. 



Fossil above "Glass Window," Eleuthera Island at Station, 2T. Living, 

 Turks Island. 



The specimens above identified have a great resemblance externally to 

 several species from the south side of Cuba, as for instance C. pannosum 

 Maynard, but the parietal tooth is short in the fossil and long in the Cuban 

 forms. Without a large and well-preserved series it is almost hopeless to 

 identify forms of this group, but the specimens obtained are admirably rep- 

 resented by the figure of hlandi in the Manual. 



Cerion (Strophiops) eleuthera P. and V., var. drupium Dall, nov. 



Cerion eleutJierw Pilsbry and Vanatta, 1896, Proc. Acad. Nat. Sci. Phila., p. 333, 

 pi. 11, figs. 19, 20; Man. Conch., 1902, XIV, p. 240, pi. 36, fig. 38. 



Fossil at Station 6, above "Glass Window," Eleuthera. Living, Eleu- 

 thera Island. 



The shell above referred to has the cylindrical form of the gvhernatorium 

 group; though the lip is not fully complete it has the outline of eleutherce, 

 from which the form differs in having fine, close, feeble riblets over the whole 

 shell. 



Cerion (Strophiops) lentiginosum Maynard. 



Strophia lentiginosa Maynard, 1889, Contr. to Science, I, p. 75, fig. 11, pi. 7, fig. 18. 

 Cerion lentiginosum Pilsbry, 1902, Man. Conch., XIV, p. 248, pi. 37, figs. 60, 61. 



Fossil in teolian rocks on the east side of Eum Cay, at Station 19. Liv- 

 ing on the west side of Eum Cay, in the interior.
