Conrad described this species with the name of locality, "Enterprise, 

 Miss." The specimen figured on plate 1 is from Claiborne, Ala., where 

 the species is not rare. It is common in Jackson, Miss., and altogether 

 occurs in so many other localities, that it may be considered as character- 

 istic for the Southwestern Tertiary. 



PERIPLOMA COMPLICATA, n. sp. PL 1, fig. 22. 



The only specimen found is of the same fragmentary shape as that in 

 which Periploma Claibornensis, Lea., sp., a species not rare, constantly 

 occurs. The fissure of the beak and the pearly nacre of the inside are 

 well seen ; the hinge with the spoon-shaped process is much more compli- 

 cated than in P. Claibornensis, as the figure shows, the process consisting 

 mainly of two concentric spoons. 



Locality. Claiborne, Ala. 



ECHINODERMATA. 



ECHINOCYAMUS HUXLEYANUS, n. sp. PI. 3, fig. 23. 



The only specimen found is fragile and damaged ; it is egg-shaped, de- 

 pressed, with rather coarse tubercles, large mouth and vent, the latter 

 near the margin ; a similar species is Echinocyamus oviformis, Forbes.* 



Locality. Claiborne, Ala. 



FORAMINIFERA. 



NODOSARIA OBLIQUA, L. Sp. PI. 1, fig. 31. 



Of this widespread species I give a figure, as it is the only specimen of 

 Foraminifera found as yet in the Claiborne Sand. The species occurs in 

 most of the many localities of the Southwestern Tertiary.
