4. Cybele from Et. E 2 (Wenlock) in Bohemia ; Meristina sp., the 

 same that, as we have seen, occurs at Zebingyi ; Dualina (?) sp. 

 a small lamellibranch possessing a considerable resemblance to D. 

 socialis Barr. and D. infiatida Barr., both from Et. E 2 (Wenlock) 

 in Bohemia ; and lastly a small species of Lunulicardium, resembling 

 L. amabile Barr., from the same horizon in Bohemia. In America, 

 and in Europe outside Bohemia, the genus is more common in 

 the Devonian period. It will be noticed that none of the char- 

 acteristic Zebingyi forms were found here, but the outcrop visible 

 is exceedingly small, and it is quite possible that the Tentaculites 

 beds would be found if a quarry were opened at this spot.

Range and distribu- . . , " .
