Melanopsis planoidea, PI. 10, fig. 10. 



Sj-n. M. planoidea Aid., Bull. Am. Pal., vol. i, p. 67, pi. 3, fig. 7, 1895. 



Aldrich's original descriptio7i. — {^Loc. cit.) 



As remarked below, this is doubtless the normal form, while 

 anita is an old incrassated form of the same species. 



Locality. — Ala.: Gregg's landing. 



Type and specimen figured. — Aldrich's collecftion. 



Melanopsis anita, PI. 10, fig. 11. 



Syn. Melanopsis anita Aid., Geol. Surv. Ala., Bull, i, 1886, p. 35, pi. 5,

 Pasithea anita de Greg., Faun. Eoc. Ala., 1890, p. 164. 

 ? Metajiopsis planoidea Aid., Bull. Am. Pal., vol. i, p. 67, pi. 3, fig. 



7. 1895- 



Aldrich's original description. — "Shell ovate, spire short, sur- 

 face .smooth, body whorl large; aperture large, angular poster- 

 iorily, caused by a thick deposit of callus; outer lip sharp, thin; 

 callus refledled below, terminating in a small excision. 



''Locality. — Ala.: Gregg's landing." 



This seems to be a true Melanopsis , though it may be an offshoot 

 of Btdlia or Pasithea. I am inclined to think this is but an old 

 incrassated form of M. plajioidea. 



Locality. — Ala.: Gregg's landing. 



Type and specimen figured. — Aldrich's colle6lion.
