Neithea bellula

This shell is medium subtrigonal, practically equilateral, fragile, the length almost equaling its height; postero-dorsal margin is slightly longer than antero-dorsal, ventral margin subsemicircular with six faint prominences.  The ears are imperfect, but appear to be conspicuous and unequal.  These were found in the Georgetown Limestone, Austin, Texas.
