fornia, bears to the Vaqueros. The position of the Sespe in the 

 Tertiary sequence of California has long been a matter of contention 

 among western geologists and palaeontologists. AVithin recent years, 

 however, this formation, occupying a stratigraphic niche between the 

 Eocene and the Miocene, has come to be referred to the Oligocene. 

 The relationship which the Tecuja beds show to the IMonterey and the 

 lithological characteristics of the red beds themselves, suggest strongly 

 a contemporaneity of deposition of the Tecuja beds and a part of the 

 Sespe at the type locality. While such a view may be held tentatively, 

 a definite assertion can not be made until a vertebrate fauna is obtained 

 from Sespe deposits in the type .section.
