During the field season of 1918, Profes-sor B. L. Clark, with a carty 

 of advanced students in palaeontology from the University of Oa^?, 



fornia, made a reconnaissance of the Tertiary formations on the south- 

 western border of the San Joaquin Valley some thirty to forty miles 

 south of Bakersfield. In the course of this study fragmentary mam- 

 malian remains were discovered in certain land-laid deposits typically 

 exposed in the vicinity of Tecuja Canon. Later Mr. E. L. Furlong 

 and the writer, at the request of Professor John C. Merriam, made a 

 careful and detailed examination of the region where the vertebrate 

 materials had been found and extended the search to Pleito Canon, 

 several miles to the northwest. 



The fauna secured from these deposits is unfortunately not large. 

 It is to be regretted also that the forms which have been found are 

 preserved in such fragmentary .state, for definite specific determination
