﻿NEW CRETACEOUS AND EOCENE FOSSILS. 277 



teriorly ; ribs about 25, irregular, prominent, acute, posteriorly distant, crenulated 

 by rugose concentric strise, on the umbo tuberculato-crenate ; summit very prominent ; 

 anterior margin obliquely truncated. Length 3i inches, heighth 2| inches. 



Locality. — With the preceding. Dr. Spillman. 



Morton's description is from the cast, mine from the shell. 



LEGUMEN, Conrad. 



The genus Legumen is founded on shells closely related to Cultellus, Schumacher. 

 Having examined specimens of the hinge in both valves, the following description will 

 indicate the genus. Oblong, much compressed, slightly gaping ; hinge of right valve 

 with two direct lamelliform teeth under the apex, and one oblique, elongated, 

 lamelliform, bifid tooth almost parallel with the inner cardinal margin ; left valve 

 with one direct, elevated, compressed tooth, with a pit on each side, the posterior 

 one widest; two very oblique, lamelliform teeth diverge in a posterior direction 

 from the apex; cardinal plate broad opposite the apex, anteriorly broad and 

 channelled. 



Legumen planulatus (Solemta,) Conrad. Journ. Acad. Nat. Sci., Vol. 2, (New 

 Series,) p. 274, pi. 24, fig. 11. 



This species has been found only in the state of casts, and is much shorter propor- 

 tionally than the preceding species, exhibiting also an impression of a rib-like callus 

 near the hinge, which callus is wanting in the others. It has not been found associ- 

 ated with the Tippah and Eufaula fossils, but occurs in the limestone of Alabama 

 and green sand of New Jersey. 



SANGUINOLARIA, Lam. 



Sanguinolaria cretacensis. PI. 46, fig. 11. Ovate, compressed ; cardinal plate 

 broad, the inferior margin of the posterior cardinal plate salient and acutely an- 

 gulated. 



Locality. — Tippah Co., Mississippi. 



The only specimen is a valve in marl showing the interior. The cardinal teeth 

 are broken off, otherwise the valve is in excellent preservation. 



TELLINA, Lin. 



Tellina Eufaulensis. Subtriangular, convex, entire, inequilateral ; anterior end 

 subtruncated ; hinge margins equally declining ; summit not prominent ; posterior 

 end acutely rounded ; left valve furnished with one bifid and one rudimentary 

 cardinal tooth ; lateral teeth distinct. 



Locality. — Eufaula, Alabama. Tuomey's collection.
