NEW HAPLOMASTODON FINDS FROM THE LATE PLEISTOCENE OF NORTHERN ECUADOR

New mastodon remains were collected in the Carchi Province, northern E cuador. The levels from which the fauna was collected are referred to the Late Pleistocene (Late Lujanian Mammal Age). On the basis of this fossil material, we conclude that probably only one species of Haploma stodon was present in Ecuador, most of tropical South America, and tem perate southwestern Brazil. At the present state of knowledge we feel it convenient to classify the different Haplomastodon demes of this fa unal province as Haplomastodon ex gr. waringi (HOLLAND, 1920).
