DALLAS HANNA AND MERLE C ISRAELSKY Department of Paleontology Introduction In 1914 Mr. G. C. Gester collected a considerable number of Tertiary fossils in Peru and soon after presented them to the California Academy of Sciences. Dr. Roy E. Dickerson, then Curator of the Department of Paleontology, intended to pre-pare a report upon the collection for publication, and he identi-fied many of the species contained therein, but before the Avork was completed he was called to other duties. Later, through the kindness of Mr. John G. Burtt of the Shell Oil Company of California, another collection made in the same region by Mr. Arthur May was donated to the Academy. The purpose of this paper is to place on record these inter-esting and valuable collections. Through the development of the petroleum bearing fonnations of northern South America during recent years much attention has been attracted to the region and several extensive reports have been published on the geology and paleontology. Large collections have been made July 21, 1925
