TO 0. Meyer — Species in the Southern Old-tertiary. 



Besides the figured piece b, I found valves of the same form 

 but larger. The umbo of the carina is placed at the apex. As 

 far as I know the literature, this is the first Lepadite from the 

 American Tertiary. 



The top of stratum b is formed by an oyster bank. In 

 stratum c I did not find a trace of a fossil, and in d, h and i no 

 determinable fossil. In e there must be made a distinction 

 between the highest part and the lowest part of it, "Highest 

 Claibornian" and "Lowest Claibornian" as there is a paleonto- 

 logical difference which, though not striking, cannot be neg- 

 lected. I found in the stratum e also a specimen of an 

 Orbitoid. The fossils in stratum g are very fragile. Larger 

 specimens could be obtained only in poor fragments, and even

the smallest could be obtained only with difficulty. The most 

 common of them seems to be Alveinus minutus Conr., which is 

 apparently one of the most characteristic fossils of the Southern 

 Old-tertiary. A specimen of Venericardia parva Lea shows no 

 approach to the Jackson angular form, and is as rounded as 

 the most rounded Claibornian specimens. A young specimen 

 of Corbula Murchisoni Lea shows the sharp carina of the Cla- 

 bornian form. 



2. Profile at Enterprise, Miss. — The profile given by Hilgard* 

 is not correct. The Chickasawhay River near Enterprise seems 

 to be little fitted to furnish a reliable profile. Each of the 

 creeks on the west side, however, shows distinctly two fossil- 

 bearing strata. The upper one contains quite a number of 

 species, but they are badly preserved. They have a Claibor- 

 nian character (for instance, Venericardia rotunda Lea) and are 

 apparently not the species which Conrad received from Enter- 

 prise,f which I could not find. The lower stratum is an indu- 

 rated sand with glauconite ; and, besides shark teeth, I found 

 nothing else in it except
