NOTE ON THE "ANALYSE DE LA NATURE " OF RAFINESQUE. By DAVID S. JOHDAIV. One of the least known of the many publications of Rafinesque is that beaiinf? the following title: "Analyse de la Nature, ou Tableau de rUnivers et des Corps Organises. Par C. S. Ifafinesqne, Palerme, 1815." Tills work consists of an elaborate scheme of classification, with defi-nitions of families and higher groups, together with a mention of the genera included under each group. In the part which treats of fishes a very large number of generic names not previously used are intro-duced. None of these are defined in any way, nor is a typical species indicated. Some forty of them, however, are substitute names, intended to be used in place of older names, which were considered by Kafinesque as objectionable. In the severe code which he seems to have adopted, generic names too short, as Naso, Raia, are regarded as objectionable and subject to change. The same is true of names too long, as Cephala-canthus, Cyprinodon. Compound names, as Serrasalmo and Scomheresox, are ruled out, as are also all generic names formed by adding " OMior?<s" or " oides " to the name of some older genus. These substitute names of Rafinesque must be regarded as having the same typical species as the generic names they were intended to replace. In case the original name is really ineligible, these Rafiues-quian names must be considered. The other generic names mentioned, those intended by Rafinesque to refer to new genera, are of course valueless as accompanied by no sort of definition or explanation. The following is a list of the substitute names: Substitute name. Page. Original name. Batrictius Daclyleptus — Nasouus Aleclis I'oliptuius Orcyinis Panotus Cephacaudia... Epiphthalmus .
