MI TEA. 

 Mitra subpoiitis n. sp. , PL 8, figs. 7, a. 



Specific characterizaticm . — General form and size as indicated, 

 by the figures; whorls about 7; apex acute; spiral whorls smooth, 

 slightly inflated; suture distinct but not deep; body whorl with 

 spiral striation at base and generally with one varix; outer lip 

 thickened; columella with four strong subequal folds below and 

 two or three smaller ones above. 



The folds on the columella of this species resemble those of 

 some groups of Volutes, but the general form is that of the 

 Mitrce, and the apex is acute. The varix is remarkable for this 

 genus or allied genera. 



Localities. — GEORGIA: Uppermost beds of the Midway hori- 

 zon as represented on the Chattahoochee at Ft. 

 Gaines. Specimens are not rare, though by no 

 means abundant. 



Type. — Paleontological Museum, Cornell Univ. 



Mitra hatchetigbeensisf , PI. 8, fig. 8. 



Syn. M. hatchetigbeensis Aid., Bull. No. i, Geol. Surv. Ala., 

 1886, p. 28, pi. 6, fig. 3. 



This form has considerable resemblance to M. hatchetigbeensis 

 but so far as observed has but two plaits on the columella 

 instead of three. The specimen herewith figured is from Black 

 Bluff, Tombigbee river, Sta. 297, of U. S. Nat. Mus. Record. 

 Less perfect specimens were collected from the same locality by 

 Hubbard and Harris, 1895. 



FUSUS. 



Fusus qvercollis n. sp. , PI. 8, fig. 9. 



Specific characterization. — Size and general form as indicated 

 by the figure; whorls, probably about 10, strongly carinated, 

 smooth above, with about twelve tooth-like, vertically compressed 

 tubercles on the carina; below the same a short distance a strong 

 spiral, raised line, still lower, a second somewhat fainter and 

 below this a third corresponding to the suture of the next whorl. 

 On the body whorl the first spiral line below the suture is also 

 fairly strong but the succeeding spirals are fainter and disappear 

 entirely on the anterior canal, which is extremely long, straight 

 and slender. The lines of growth are evident on specimens of 

 this species but they are not crossed by fine spirals, hence the
