420 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 5° 



The new Eocene forms, Turritclla (martinezensis Gabb, var. ?), 

 lompocensis, and Pccten yneziana, are from the brownish sandstone 

 of the Tejon formation which makes up a considerable portion of the 

 Santa Ynez Range south of Lompoc and Santa Ynez. Within this 

 formation in the territory mentioned are found the following fossils :

The lower Miocene or Vaqueros formation is stratigraphicallv 

 above, but closely associated with, the Tejon, and consists largely of 

 coarse conglomerate and sandstone, with some associated limestone 

 near the top. The new species, Purpura vaquerosensis, Pecten van- 

 vlecki, and Modiolus ynezianus, are from the sandstone portion. 

 Associated with the above forms in the Vaqueros formation, in the 

 western end of the Santa Ynez Range, are the following species :
