Some detached segments of Nodosaria, without doubt 

 belonging to the above species, were found in the Califor- 

 nian foraminiferal rock. N. longiscata is well known as a 

 species occurring in the Eocene, Miocene and Pliocene 

 formations.

This Tertiary foraminifer is here represented by small 

 specimens comparable in form but without the spinose seg- 

 ments which the species exhibits when fully grown. 



Santa Clara County, California; frequent.

A fragment of an obliquely costate shell was found in the 

 material examined, which appears to belong to the above 

 typical species. It has also been recorded from the Mio- 

 cene of Norfolk, Virginia.
