Abstract
IT has been frequently pointed out that the advancement of systematic zoology is best served, in the present state of the science, not so much by the description of new species as by the revision and putting in order of the species that are supposed to be already known. Of the kind of work that is most needed, an excellent example is provided by this monograph by Dr. Grace Pickford. The laborious investigation of the very large collections made in South Africa by the author and by others seems to have been done with great thoroughness and care. The results are set forth in very clear fashion and—so far as a non-specialist may see—with sound judgment.
