CARDIUM TUOMEYI, n. sp. PI. 4, figs. 33, 13a. 



Shell ovate, thick through the umbones ; ribs numerous, about forty - 

 four in number, flattened above and indented with scars of spines ; spaces 

 between the ribs much smaller than the ribs themselves ; a few small, 

 scattered spines near the beaks, which are central and raised ; muscular 

 scars strongly marked. 



Locality. Nanafalia, Ala. 



Differs from the previous species described by its more numerous ribs, 

 more rounded form, smaller spines and thicker shell. The figure 13a 

 shows the teeth of the left valve. 



CARDIUM EUFAULENSE, Con. PI. 6, fig. 5. 



A cretaceous fossil (or described as such) received from Dr. William 

 Spillman, of Mississippi. Probably an error in locality. 



VERTICORDIA EOCENSIS, Langdon. PL 6, fig. 13. 

 V. eocemis, Langdon. Am. Jour. Sri., March, 1886. 



Figured at the request of Mr. Langdon. 



ISucuLA MONROENSIS, n. sp. PL 4, fig. 2. 



Shell ovate-elliptical, subangular behind ; surface covered with raised 

 concentric ribs, sharp on their upper edge and slope downward toward 

 the ventral margin ; beaks recurved ; lunule faintly marked, but large ; 

 cavity of the shell rather deep ; margin crenulated. 



Locality. Calcareous sand-bed lower part of Claiborne Section, Monroe 

 County, Ala. 



CUCULL^EA TRANSVERSA, Rogers. PL 4, fig. 11, lla. 



The figure is from a specimen found at Gregg's Landing, Ala. Very 

 large individuals two and one-half inches in length occur. Prof. Heil- 

 prin has placed the genus Cucullcea in Area as a subgenus, and changes 

 the name of this species to C. Rogersi, because the name transversa is pre- 

 occupied in Area; but as both Try on and Zittel consider the genus a good 

 one, the old name ought to stand. 



PECTEN (PLEURONECTIA) ALABAMENSIS, n. sp. PL 4, fig. 8. 



Shell small, suborbicular ; upper valve covered with equidistant con- 

 centric lines which run over upon the anterior ear ; a few raised radial 

 lines upon the center and anterior side ; ears small ; right valve nearly
