PALEONTOLOGY: C. STOCK A TARSIID PRIMATE AND A MIXODECTID FROM THE POWA Y EOCENE, CALIFORNIA By CHESTER STOCK

Introduction.-Following the discovery and description of a titanotherel in the Poway sands of San Diego County, continued excavation in this important Eocene horizon has produced small lots of mammalian remains. One of these included specimens of a tarsiid primate and a mixodectid. Worthy of mention is the fact that the former represents a third member of the Tarsiidae to be discovered in the early Tertiary of the Pacific Coast region. Since the Poway fauna possesses considerable significance in any attempt to correlate the later Eocene horizons of the Pacific Coast with those of the Cordilleran Province, it seems desirable to place on record these new mammals from the Poway.
