Cornulina armigera, (young var.), PI. 4, fig. 4. 



Syn. Heilp., /. c, pi., fig. 7. 



Heilprin gives no locality nor name to his figure 7, the same 

 specimen herewith figured. Specimens in the Texas State Sur- 

 xe}' collecT;ion from Atascosa county are similarly ornamented. 

 In Harris' MS. report on the Eocene mollusca of Texas, 1893, 

 we read, "The facft that these young specimens are without 

 spines on the body whorl can scarcely be regarded as sufficient 

 reason for referring them to a distindl species. The same remark 

 applies to their slenderer form. Specimens have already been 

 found that are intermediate between the varietal and the typi- 

 cal form. 



'^ Localities. — Peeler's ranch; and S. E. of Campbellton, Atas- 

 cosa county, Tex." 



In Harris' forthcoming Bulletin on the Lignitic Stage many 

 marked varieties of this species will be given. In the Texan 

 report above referred to, a varietal name for the smooth form 

 was proposed, viz., var. heilpriniana. 



Notes on Various Forms. 

 Mathilda regularis Meyer, Pl. i_ figs. la, b, c. 



This specimen was obtained on the upper part of the bluff at 

 Vicksburg, Miss. The type came from Red Bluff, Miss. This 

 figure is much more accurate and complete than the original. 



Solariorbis subangulatus Meyer, var., Pl. 4^ fig. g. 



Shell small, depressed, whorls five, rapidly increasing in size; 

 surface covered with fine revolving lines, umbilicus deep; aper- 

 ture approaching quadrate, suture distincft. 



This agrees with Me^'er's description and figure. If new, 

 how^ever, it may be called 5". liniferiis. Type was obtained at 

 Jackson, Miss. 



Locality. — Alabama: Chodlaw Corner, Wood's Bluff horizon.
