Show 1896.] "INDEX. GENERUM ET SPECIERUM ANIMALIUM." 613 Species " indett.," if figured, are included in the index. Misprints are quoted only if considered liable to cause confusion. The following is an example of the Index as proposed to be carried out. The inclusion of an alphabetical list of species undev each genus name is a matter for consideration, if ever the M S. comes to the printing office. It can be adopted or rejected at option, and if adopted the duplicate set of slips will be available for the purpose. In arranging the Index for printing it is proposed to print one alphabetical list from beginning to end; the species names and the genus names falling into one order according to the arrangement of their spelling. The lollowing are the reasons for arranging the work under species and not under genera, as in the ' Index Kewensis':- 1. No synonymy of species is attempted: that depends on the idiosyncrasy of the systematist. 2. Any attempt at specific synonymy would be fatal to progress, as experience shows that vast changes may take place in a single year. 3. An arrangement under species permits of a generic synonymy, for by running the eye down the second column of the printed work, it will be possible to ascertain the various generic names with which a particular species name has been connected.

B From this description of the 'Index Generum et Specierum Animalium,' it will be seen that a manuscript comprising 130,000 references is already in existence and is available for daily reference. Sir W m . Flower, Dr. Giiuther, and Dr. Woodward took so . much interest in the original scheme that they at once offered the necessary space and cabinets for the storage of the manuscript at the British Museum (Natural History)-an offer of considerable value, as it not only renders the M S . easily accessible to those vyishing to consult it, but ensures safety from fire and other destructive agencies.
