[Avifauna Italica, nuovo Elenco Sistematico delle Specie di Uccelli, 
stationarie, di Passaggio o di accidentale Comparsa in Italia; coi nomi 
volgari, colla loro distribuzione geografica, con notizie intorno alia 
loro Biologia, ed un esame critico delle Yariazioni e delle cosidette sotto 
specie. Dal Enrico Hillyer Giglioli. Florence, 1907. Pp. i-xxiv, 1-784.] 
In the year 1886 Professor Giglioli earned the gratitude 
of the ornithological world by compiling his first ‘ Avifauna 
Italica,’ consequent upon a shorter memoir in the Roman 
Annals of Agriculture. He now gives us, in what may be 
termed a second edition, the results of his labours from 1886 
to the present time, pending the completion of his illustrated 
folio work, f Iconografia delP Avifauna Italica.’ Much new 
information has been amassed in these twenty years, and the 
aid of the Ministers of Public Works and Marine has been 
invoked, and not in vain, to the assistance of Orni¬ 
thologists, chiefly with regard to the Migration and the 
Distribution of species. Further statistics are, as the 
author tells us, still needed ; but we have here a very satis¬ 
factory account of the birds of the Kingdom of Italy. 
Proper attention is paid to the new subspecies or species 
that have occurred in the country, more especially where 
“ neogenesis," or the birth of new forms (e. g. Athene 
chiarardia), has been asserted; due weight is also given to 
the question of geographical races. 
Several of the specific names used are not those with 
which we are most familiar, but it would be impossible in 
a short space to discuss their validity. 
We must, in conclusion, draw particular attention to the 
excellent Introduction, which gives an account of the progress 
of Ornithology in Italy and a statement of the Professor's 
creed. He declares himself an unsparing opponent of the 
fashion of founding new species or subspecies on very slight, 
or mere individual, characters, and considers that such 
characters are unfortunately often confounded with those
