THE Committee of the Transvaal Museum has just published, through the Cambridge University Press, indexes to all the volumes of the Annals from vol. 6 (1917-20) to vol. 11 (1924-26). The indexes are thorough guides to the systematic contents of the volumes, and show new genera, subgenera, species, subspecies and the main reference in heavy-faced type. But they do not contain authors' names or titles of papers contained in the volumes.
