 OF SOUTHERN CALIFORNIA 



DAVID STARR JORDAN and JAMES ZACCHEUS GILBERT 



A small number of fishes has been obtained about Los Angeles from 

 sandstones and shales. which lie above the Puente or Monterey deposits 

 and which are regarded as of Pliocene age. In these rocks there are no 

 diatomaceous deposits and the fishes are of a different character from 

 those found imbedded in the masses of diatoms. 



The following localities are represented: 



1. Sunset Bluff, near Broadway Tunnel : sandy shales of the lower 

 Pliocene. ARNOLDINA. 



2. Third Street Tunnel : clay shale of the upper Pliocene. ECTASIS. 



3. Fourth and Hill Streets : clay shale, upper Pliocene. CAR- 

 CHARODON. 



4. Temescal Canon, Sierra Santa Monica. 



5. Rustic Canon, Sierra Santa Monica. 



6. Port Harford.

 names in italic) :
