Schizodus sp. (Fig. 8). The generic reference of the specimen 
referred to this genus is not known to be correct, the cardinal 
margin being imperfectly preserved. The shell has a general 
resemblance to Schizodus cuneus. In the thin representative of 
the Bedford-Berea at Indian Fields, Kentucky. 
Another specimen of doubtful generic affinities (Fig. 9). bears 
some slight resemblance in outline to the species described by 
Hall as Lunulicardimn fragile, but there is no trace of radiating 
striae and the species may belong to an entirely different group 
of lamellibranch shells. In the thin representative of the 
Bedford-Berea at Indian Fields, Kentucky.
