beaded spirals, alternating with single plain spiral threads, followed 

 by 8 or 10 smaller, mostly simple and closely adjacent threads, one 

 or two of which show a tendency toward beading. The canal is short 

 and twisted, and obscurely spirally threaded. Height of three visible 

 whorls, 42; diameter at decollate earliest whorl, 11; maximum 

 diameter of last whorl, 27 mm. 



Locality. — Station 7079, on the east bank of Flint River, below the 

 mouth of Blue (or Russell) Spring branch, at Mascot Point, in chert 

 blocks; Vaughan, Cooke, and Mansfield, 1914. U. S. Nat. Mus. 

 Cat. No. 160728.

Plate 86, fig. 4. 



Cassis sulcifera Sowerby, Quart. Journ. Geol. Soc. of London, vol. 6, pt. 1, May, 

 1849, p. 47, pi. 10, fig. 1. (Santo Domingo.) 



Localities. — Station 3381, at the base of the bluff at Little Horse- 

 shoe bend, on the Flint River, 4 miles below Bainbridge, Decatur 

 County, Georgia, just below the mouth of Blue (or Russell) Spring 

 branch, in fossil coral reef; T. W. Vaughan, 1900; U. S. Nat. Mus. 

 Cat. No. 166785. Also at station 3388 at Red Bluff, on Flmt River, 

 7 miles above Bainbridge, in the upper fossiliferous stratum at that 

 locality; at station 7074, at Hale landing, 7 miles southeast of 

 Bainbridge, on the west bank of Flint River, in coralliferous chert; 

 at station 7079, on the east bank of Flint River, at Mascot Point, 

 in chert blocks; at station 7096, at Red Bluff, on the west bank of 

 Flint River, 7 miles above Bainbridge; at station 7150a on the 

 east bank of Flint River, just below the wagon bridge, from loose 

 blocks of chert; Vaughan, Cooke, and Mansfield; and from the Oli- 

 gocene of Santo Domingo ; Sowerby. 



Though no complete specimens were found, the identification of 

 the species appears to be certain. 



CASSIS GLOBOSA Dall. 



Cassis (Phalium) globosum Dall, Trans. Wagner Inst. Sci. PMla., vol. 3, pt. 1, 

 1890, p. 161; pt. 2, 1892, p. 262, pi. 20, figs. 6, 11. 



Locality. — Station 3381, at the base of the bluff at Little Horseshoe 

 bend, on the Flint River, 4 miles below Bainbridge, Decatur County, 

 Georgia, just below the mouth of Blue (or Russell) Spring branch on 

 the east bank of the river; T. W. Vaughan, 1900. U. S. Nat. Mus. 

 Cat. No. 166786. Also in the Jacksonian Eocene of Ocala, Florida, 

 and the Oligocene marl of the Chipola River, Calhoun County, 

 Florida. 



Unidentifiable remains of a species of Cassis from station 3401, on 

 the west side of Flint River, at Cherry Chute, 3 miles below Bainbridge, 

 probably belong to this species.
