tion. Prof. Harris mentions finding one species at Fort Gaines 

 on the Chattahoochee and another (which is probably the one 

 subsequently described mile north of Ripley, Miss.) They 

 are figured and named as they seem to be rare and peculiar to 

 this horizon. 



Cypraea sp. ? PI. 2. Figs. 2, 3. 



Shell small ; surface smooth ; basal callus extending par- 

 tially over the sides ; outer lip expanded ; extremities somewhat 

 pointed. One fragment shows the dentition, consisting of over 

 20 small teeth on the inner lip. Length of the larger fragment 

 1 5 ram. 



Locality. — Sucarnoochee beds, one and three miles south of 

 Estella, Ala. on Pursley Creek. 



Types. — Ala. Museum of Nat. Histor^^ 



Seems to be rather close to Cypr^Ea Sniithi nobis from 

 Gregg's Ldg., Ala. 



Siphonalia quadrilineata, n. sp. PI. 2. Figs. 4, 5. 



Shell resembling the Fiisiis subscalarinus Heilpr. Whorls 

 eight, two embr3'^onic, the balance more or less cancellated ; 

 longitudinal costse somewhat rounded; spiral striae very numer- 

 ous, four fine ones between a coarser line ; the volutions are ap- 

 pressed at the suture ; the spiral strise cross over the costse and 

 the coarse lines make nodes of intersections ; canal reflected and 

 twisted : the outer lip on the type is broken away but appears to 

 have been smooth internally ; inner lip somewhat thickened. 

 Length 17 mm. 



Locality. — Pugh's Branch of Satilpa Creek, Clark Co., Ala. 

 Gosport Sand. 



Type. — In Ala. Museum, University Ala. 



Remark. — One is rather rash to attempt anew form herewith 

 but the surface ornamentation is peculiar and seems to be new. 



Cerithiopsis estellensis, n. sp. PI. 2. Fig. 10. 



Shell minute ; whorls eleven or more, the first two smooth, 

 the next two with raised ribs ; the balance showing two strong, 

 heavily beaded spirals on the peripheral part of each whorl with
