Bitlimina buchiana has been noticed in many Tertiary 

 beds. It was originally described from the Miocene of the 

 Vienna Basin and it has been found by Dr. Bagg in the 

 Miocene of Norfolk, Virginia. It was also found by Dr. 

 Egger in the Older Pliocene of Monte Bartolomeo. 



California (first sample very rare), and from a well in 

 Santa Clara County, California; frequent.

This species first makes its appearance in the Miocene 

 and it occurs in succeeding deposits to the Recent. Egger 

 records it from the Older Pliocene of Monte Bartolomeo. 



The specimens from California are very variable as to 

 proportionate length and breadth. 



Santa Clara County, California; very common.

Egger describes this variety from Monte Bartolomeo. It 

 is characterized by the lengthened test and the comparatively 

 sharp-pointed aboral end. 



Santa Clara County, California; common.
