This apparently unfinished study of the still poorly described La Brea skull was written in 1914. Measurements by Kroeber and John C. Merriam and photos by Merriam are included. The skull is identified with the earliest of three racial subtypes of California Indians recognized by Kroeber. Robert F. Heizer provides data on a recent radiocarbon date at La Brea and explains that Kroeber's three subtypes were later verified by the detailed work of E. W. Gifford.
