In previous papers , published mostly in these PROCEEDINGS, have appeared some of the paleontological results of explorations conducted in the Sespe deposits of Southern California. While the field efforts south of the Santa Clara Valley, Ventura County, were rewarded by rather startling results, no small amount of irritation was felt because of failure to find fossil vertebrate remains in the Sespe at the type locality north of the Santa Clara Valley. For, as is now known, the Sespe is not of same age throughout its stratigraphic thickness or at the several localities where fossil mammals have been found in it. It is, in fact, a series of beds that range in age from at least the upper Eocene to apparently the lower Miocene. Thus it seems especially important to determine by means of vertebrate evidence the age relationships of the type Sespe on Sespe Creek to that portion of the Sespe whose age is already established south of the Santa Clara Valley. With this problem in mind the rugged terrain north of the Ojai Valley, Ventura County, and in the immediate vicinity of Sespe Gorge was critically examined during the summer of 1937 by a field party of the California Institute of Technology. The outcome of this work was the discovery of titanothere remains in the lower portion of the Sespe, including a palate with teeth permitting a comparison with the titanotheres known from lower Tertiary horizons of southern California.
