These are from (a) Upper Triassic deposits at Bear Cove, 

 Brushy Slope, "Camp Wemple," and North Fork in Shasta 

 County; (b) from a fresh-water deposit of marl rock of Miocene 

 age in a cut in the Canal near Truckee, California; (c) from a 

 hard dark brown argillaceous sandstone belonging to the Chico 

 formation of the upper Cretaceous, near Martinez, California; 

 and (d) from Miocene deposits six miles north of Santa Ana, in 

 Orange County; also with these is a collection from Quaternary 

 deposits near Fossil Lake, Oregon. 



2. An enormous collection of sharks' teeth belonging to the 

 California Academy of Sciences, obtained by Mr. Frank M. An- 

 derson, Curator of Palaeontology in the California Academy of 

 Sciences, from Lower Miocene deposits at Barker Ranch, there 

 collected by Mr. John Barker, from a point four miles east of 

 Oil City in Kern County and in Kern County, from Pliocene 

 (San Pablo) deposits, Coalinga and Zapata Chino Creek in 

 Fresno County, the same horizon as that from which Dr. Blake 

 sent specimens to Professor Agassiz in 1855. This collection, with 

 the exception of a few duplicates reserved for the collections of 

 Stanford University and the University of California, was de- 

 stroyed by the .fire of April 18, 1906. 



3. A collection of fossil fishes made from Miocene sandstones 

 and marles about Soledad pass, and from Brown's Canon above 

 the Soldiers' Home near Santa Monica, in Los Angeles County, 

 by Dr. Stephen W. Bowers of Los Angeles (recently deceased). 

 These belong to the Museum of Stanford University. 



4. A collection of sharks' teeth from the Santa Monica range 

 near Santa Monica and Port Los Angeles, the property of Dr. J. 

 J. Rivers. These rocks are regarded as of Pliocene age. 



5. A small collection from Miocene deposits on Santa Anita 

 Ranch, five miles west of Gaviota, in Santa Barbara County, 

 brought to the University of California by Mr. W. J. Raymond. 



6. A small collection made in Miocene marls near Shorb, in 

 Los Angeles County, by Dr. Ralph Arnold and Mr. Delos Arnold. 



7. A collection of fragments of Etringus scintillans from 

 Monterey shales on Brea Canon, Orange County, made by Mr. 

 W. O. Clark of the U. S. Geol. Survey. 



It may be premised that Palaeontology is never an exact 

 science, and that almost all conclusions and determinations in
