In his 1917 letter in the American Museum Journal, Broom provides a brief, two-page account of the discovery of the Boskop 1 calvarium and other remains. In this work he coins the name Homo capensis for the Boskop 1 specimen and remarks that it is most similar to Cro-magnon. See also Gregory 1921 for comments on the same specimen, which Gregory names Homo sapiens Boskop (nomen numdem).
