the same type as that of No. 2 but containing some forms as 
Tellina (?) undulifera, Turritella infragranulata, and Brachysphingus 
firatus, not present in the lower beds. One minute specimen of 
the characteristic Tejon form, Modiola ornata, was obtained at 
this horizon. 
At Locality No. 4, near the upper limit of the Martinez, 
about one third of the fauna is composed of species known from 
the Tejon. Of these forms Dentalium stramineum is a long-lived 
species ranging from Chico to Tejon. Cardium Cooperi, though 
known from Tejon beds, is not a common or characteristic fossil 
of that group, while it ranges through the Martinez and is one 
of its most characteristic species. The Cardita belongs to the 
Tejon species described as Hornit by Gabb but may be a new 
variety. MJegistostoma striata, Tellina Horn and the Morio seem 
to be typical Tejon forms and are not found below the uppermost 
beds of the Martinez. The Ficopsis sp. is a form known from the 
Upper Martinez and Lower Tejon. Imperfect specimens of a 
foraminifer related to Nummulites are abundant at this locality. 
Though the fauna at this horizon is certainly closely related to 
that of the true Tejon, only three good species are common or 
characteristic forms in that group. 
t An asterisk indicates common or characteristic; a dagger, rare or characteristic 
of some other horizon.
