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

 on the Chattahoochee and another (which is probably the one 

 subsequently described Y-z mile north of Ripley, Miss.) The}'- 

 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- 

 tiall}^ 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 

 15 mm. 



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

 Estella, Ala. onPtirslej^ Creek. 



Types. — Ala. Museum of Nat. Histor5^ 



Seems to be rather close to Cyprcea Smithi nobis from 

 Gregg's lydg., Ala. 



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



Shell resembling the Fnsus subscalarinus Heilpr. Whorls 

 eight, two embryonic, the balance more or less cancellated ; 

 longitudinal costae somew^hat rounded; spiral striae very numer- 

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

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

 the coarse lines make nodes of intersections ; canal reflected and 

 twisted : the outer lip on the tj^pe is broken away but appears to 

 have been smooth internally ; inner lip somewhat thickened. 

 Length 17mm. 



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 a new 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, 



heavih^ beaded spirals on the peripheral part of each whorl with
