122 PLEIOCENE FOSSILS. 



TEEEBELLUM E T I W A X E N S I S . — {New Species.) 

 Plate XXVI. Figs. 9 and 10. 



T. testa subulata, elongata; anfractibus striis duabus prominentibus spira modo intortis ab 

 suturibus equidistantibus, aliis rnediis tenuis striis in anfractuum utroque impressis. 



Description. Shell subulate, elongated; with two prominent spiral striae equidistant 

 from the sutures, and fine intermediate ones on each whorl. 



This shell somewhat resembles T. alticostata, of Conrad, a Meiocene species from 

 Maryland, and hitherto considered identical ; but upon comparing a number of individuals 

 from both localities, we satisfied ourselves they are specifically distinct. T. alticostata 

 is profoundly carinated near the base by a prominent spiral striae or rib, the other stria? 

 are comparatively quite small; the whorls are also compressed above.

Locality. Pee Dee ; Goose Creek. Casts very abundant at latter locality.

TEEEBELLUM BURDEN II. — (New Species.) 

 Plate XXVI. Fig. 11. 



T. testa subulata, turrita; anfractibus complanatis, spiratim costatis, transverse undanti- 

 bus striis; costis out crenulatis aut granulatis. 



Description. Shell subulate, turrited; whorls flattened- spirally ribbed, and trans- 

 versely striated with waved striee, which give the ribs a crenulated or beaded character. 



We dedicate this species to our deceased friend and co-laborer, Dr. Thos. L. Burden. 



Plate XXVI. Fig. 11, Natural size: The crenulations on the ribs are imperfectly 

 figured in our drawing. 



Locality. Pee Dee. Museum, College of Charleston.
