THOSE interested in zebras and quaggas will find an excellent account of these animals in Dr. Griffini's little book (1), which is one of the series of useful manuals edited and issued by Ulrico Hoepli, of Milan. That he has thoroughly grasped the conclusions of the most trustworthy recent authorities is shown by his discussion and rejection of the claim that the existing striped Equidæ can be logically entitled Hippotigris, by his adoption of the view that four, and only four, species, namely, Equus grevyi, E. zebra, E. foai and E. quagga, the latter including as subspecies all the so-called burchelli forms, can be admitted, by his summary of the evidence supporting the cela-tivc significance of the coloration, and of the evidence favouring the view that the pale, and not the dark, bands are in reality the “stripes.” Writing as an expounder rather than as an original researcher, Dr. Griffini is, of course, aware that his classification and synonymy of the local races of E. quagga must be regarded as tentative instead of final; but, considering the difficulties. of the question, his attempts at its settlement, although not above criticism, do credit to his perspicacity. We have only one serious fault to find with the book. It has no index. In the place where the index should be is a complete list of the author's contributions to zoology, which show that his time has been mainly devoted to the study of systematic entomology. Perhaps it is to the training thus acquired that is to be attributed his masterly handling of the subject-matter of this volume. (1) Le Zebre. Studio Zoologico Popolare. By Dr. Achille Griffini.
