A well known Tertiary species ; this form has been pre- 

 viously noted by A. Woodward from artesian well borings 

 at Atlantic City, Quinton and Beach Haven, in New Jersey. 



A . grosserugosa is somewhat difficult to separate from 

 JVonionina umhilicaUila, inasmuch as the aperture is not 

 always a safe distinction, for the obliquel}'^ apertured 

 Anomalines pass insensibly into the symmetrical Nonionine 

 forms. A. grossei'itgosa is perhaps coarser in shell struc- 

 ture and has its chambers more strongl}'^ inflated than N. 

 umbtltcatula. 



Santa Clara County, California; frequent. 

 Anomalina rotula d'Orbigny.

This species by gradational forms appears to pass into 

 Ti'uncatulina Jtngeriana d'Orb., sp. It is well known as 

 an Eocene and Miocene fossil. 



Santa Clara County, California; frequent.

 and in deposits at the present day at considerable depths. 



California, in both samples; very common.
