5 Aldrich, Eocene Fossils 



Ervilia meyeri, n. sp. 



Plate I, fig. 7 



Shell small, nearly equilateral, surface covered with num- 

 erous close-set raised lines becoming somewhat coarser near 

 the ventral edge. Beak low but pointed. Interior polished. 

 Posterior muscular scar well defined, the anterior very faint. 

 Cardinals rather strong ; laterals doubled in the left valve. 



Length 4 ; height 2.5 mm.

Named in honor of Dr. Otto Meyer, one our early work-

0. 



Akera texana, n. sp. 



Plate II, fig. 1 



Shell medium, substance extremely thin, surface smooth 

 except some wrinkles where the body whorl meets the sunk- 

 en spiral area. Strongly depressed ; whorls about five, very 

 sharply defined at the apical end with a slightly reflected edge. 

 Umbilical part bordered by a reflected edge. 



Length 13 ; breadth 10 mm. 



Lower Claiborne Eocene of Smithville, Tex. 



This is a new genus to our Eocene and rare no doubt on 

 account of its very fragile shell. Several examples were obtain- 

 ed but all went to pieces on drying. 



Scobinella newtonensis, n. sp. 



Plate II, fig. 2 



Shell rather solid, medium size ; whorls nine or ten ; 

 apex slightly bent, embryonic whorls four in number in per- 

 fect specimens ; a raised line starting just below the suture 

 on the next whorl, which becomes more prominent on the 

 latter whorls, or roughly tuberculated ; the median part of
