Bulla petrosa Conbad, Amer. Jouru. Sci., ser. 2, vol. 2, p. 399, 1846, with 

 figure. Not Bullina petrosa Conrad, Amer. Journ. Sci., ser. 2, vol. 5, p. 

 433, 1848, from Miocene of Oregon, nor Bulla petrosa Conrad, in Dana,

Rare in the Tampa silex beds, where it was first found by Conrad 

 and later by Dall. U. S. Nat. Miis. No. 97488. 



This belongs to the typical section of the genus with perforate 

 apex and resembles Bullaria solida^ but is of smaller size. 



This species has also been collected from the Oligocene limestone of 

 Jacksonboro, Georgia.

 Plate 6, fig. 6. 



Shell small, subovate, anterior third spirally striated, posterior 

 two-thirds smooth or faintly marked by incremental lines; whorls 

 involved, thin, the apex depressed, showing only the external whorl; 

 outer lip as long as the shell, thin, simple; anterior third with jEine 

 spiral striae, at first close, later coarser and with wider interspaces; 

 around the minutely perforate umbilicus there is a narrow space free 

 from striae ; aperture behind extending beyond the apex, and rather 

 narrow, in front wider; body with a thin wash of callus; pillar lip

Tampa silex beds at Ballast Point, Tampa Bay, Florida. One 

 specimen from the Post collection, U. S. Nat. Mus. No. 165027. 



This species may belong to the genus Haminea, but the specimen 

 is hardly perfect enough to be positive as to its proper location.

This group was associated with Buccinum by Linnseus, with Tui'- 

 rltelJa and Scalaria by Bolten, and with Cerithium by Say. The 

 name was used for Turritella in the Museum Calonnianum. A revi-
