yet been published. It appears (p. 225) that ten specimens 
of the Emperor Penguin (^Aptenodijtes forsteri) were captured 
alive, but made their escape from the enclosure in which 
they were confined. We hope that the National Antarctic 
Expedition will not return without some living examples 
of this fine bird. Its near ally, A. patachonica, does well 
in captivity. 
6. Bryan's Key to the Birds of the Hawaiian Group. 
[A Key to the Birds of the Hawaiian Group. By AVilliam Alanson 
Bryan. Honolulu, 1901. 4to. Pp. 76.] 
The Curator of Ornithology in the Bernice-Pauahi- 
Bishop Museum furnishes us with a key to the Hawaiian 
Avifauna, which may be useful to those who are studying 
the remarkable forms of that group. It begins at the bottom, 
after the American fashion, and contains diagnoses of 120 
species. We cannot say that we admire the 15 photographic 
plates of dead birds that illustrate the work, though they 
will doubtless tend to assist in the determination of the 
species. 
We are told, in the Preface, that the Museum in question 
" now possesses the most representative collection of the 
Hawaiian Avifauna extant,^^ containing upwards of 600 
specimens, amongst which is the famous Mills Collection, 
and that constant additions are made to it bv the Museum^s 
skilled collector, Mr. A. Seale. 
We venture to suggest that an octavo Handbook of the 
whole Hawaiian Avifauna, with references to the two great 
illustrated works of Wilson and Evans and of Rothschild, 
would be a desirable undertaking.

Prof. Burckhardt describes and figures the nestling of 
Psophia and the plumage of the young of Rhinochetus. He 
notes that the colour of the nestling of Psophia has no
