CAPULUS COMPLECTUS, n. sp. PI. 6, figs. 1, 1 a. 



Shell flattened, irregular in form ; whorls three, the first two forming 

 a spiral on the body whorl ; surface finely striated with concentric lines. 

 Interior edged ; a large horseshoe muscular impression, very slightly im- 

 pressed, shows the generic position. 



Localities. Wood's Bluff Group, Hatchitigbee, and Lisbon, Ala. 



Found occupying the cavities of other shells. Young specimens might 

 readily be mistaken for Velutina; older forms resemble an operculum. 

 In young shells the nucleus is about central; in older forms on the right 

 side; looks like Pileopsis squamce/o^mis, Lam., from the Paris basin. 



No. 1 is from Wood's Bluff ; 1 a. from Hatchetigbee. 



SCALARIA WHITFIELDI, Aldr. PI. 1, tig. 18. 

 Scalaria Whitfieldi, Aldr. J. C. S. N. H., July, 1885. 



SCALARIA OCTOLINEATA, Con. PI. 1, fig. 22. 



See the Jour. Gin. Soc.' Nat. Hist, for notes upon this species. 



TURRITELLA BELL1FERA, Aldr. PI. 1, fig. 13. 



Prof. Heilprin considers this form as a variety of T. humerosa, Con., 

 but I prefer to let it remain pending a .careful review of these difficult 

 forms. 



CERITHIUM LANGDONI, Aldr. PL 1, fig. 14. 

 Cerithium Langdoni, Aldr. J. C. S. N. H., July, 1885. 



CERITHIUM TOMBIGBEENSE, n. sp. PL 3, fig. 7. 



Shell elongated, whorls probably twelve ; suture distinct, situated in a 

 depressed space ; surface of the uppermost whorls smooth, those follow- 

 ing transversely striated the lower ones, with numerous oblique longi- 

 tudinal ribs, rising into tubercles upon the center of the body whorl and 

 the two next above ; a wavy line just below the suture, making a slight 

 shoulder to the whorls. Lines of growth sigmoid, fine and numerous 

 upon the body whorl, obsolete above. Aperture ovate, outer lip reflected 

 below, making a short, open canal. 



Locality. Wood's Bluff, Ala. 



Only one specimen found ; the mouth is broken away, rendering it im- 

 possible to determine its generic position absolutely. The apex is also 

 missing, but is probably sharp. Suggests the genus Melania.
