 Monterey County.

The author discusses the age of the formation afterward called by 

 the California geologists the Chico group. Newberry admits the Ter- 

 tiary character of a part of the fossils, but is inclined to refer the 

 formation to the Cretaceous, because of the presence in it of Ammo- 

 nites, etc.

Report on the Palaeontology of the survey; by T. A. Con- 

 rad. Chapter XXIX, pp. 189-196, with 10 plates. 



The author remarks that the Miocene of Santa Barbara contains a 

 group of shells more analogous to the fossils of the Atlantic slope 

 than to the existing shells of California ; but it is evident that there 

 must be subdivisions in the Tertiary deposits of California, which 

 range between the Eocene and Pliocene periods, for the group of the 

 Estrella Valley and Santa Ynez (Barbara) Mountains does not appear 

 to contain one species, even, analogous to any in the Santa Barbara 

 beds, and, on the contrary, some of them remind us of the existing 

 Pacific fauna. 



The author describes and figures the following new species: 



From Santa Margarita, Salinas Valley : Hinnetes crassa. 



From San Rafael Hills and Santa Barbara County : Pecten Meeki; 

 P. altiplicatus ; Arcopagia undo. 



From Carrizo Creek, Colorado Desert, and Estrella River Valley: 

 Pecten deserti, Conrad; Palliuvi Estrellanum; Spondyhis Estrellanus; 

 Arcopagia unda; Cyclas Estrellana; Ostrea panzana; Glycimeris Es- 

 trellanus; Balanus Estrellanus ; Astrodapsis Antiselli. 



From Santa Ynez and Santa Ynez Mountains: Pecten discus; 

 Pachydesma Inezana; Pecten magnolia; Crassatella collina; Mytilvs
