craft, have enabled him to bring together a most wonderfully interesting 

 and instructive series of pictures of wild birds in life, illustrating the 

 nesting habits, poses, and manner of flight of a large number of species, 

 some of which have not heretofore been so successfully and fully portrayed 

 by the camera. The scenes visited include not only many portions of the 

 Atlantic coast from the Florida Keys to Labrador, but many points in 

 the interior. The accompanying text is always pertinent, and full of first- 

 hand information, rendering the book of permanent value as a record of 

 bird-life. The publishers have done their share in making the book attrac- 

 tive in its general make-up, and in the care evidently bestowed upon the 

 reproduction and printing of the illustrations. — J. A. A. 



Sharpe on the Birds of the Antarctic Regions. 1 — Naturally the list of 

 species here treated is not large, numbering only 25, and consists wholly 

 of Water Birds, of which 3 are Penguins (Sphenisciformes), 17 are Pro- 

 cellariiformes, 4 are Lariformes, with a single species of Cormorant (Pele- 

 caniformes). Nearly half of the text and nearly all of the text illustra- 

 tions relate to the Adelia Penguin {Pygoscelis adelia), of which there are 

 two colored plates, representing the adult, the young, and the eggs. 

 Under each species is given first its synonymy and other bibliographical 

 references, with a list of the specimens brought home by the expedition, 

 followed by appropriate biographical matter. Much of this is compiled 

 from the reports of previous Antarctic expeditions, thus bringing 

 together practically all that is known of the life-histories of the species 

 treated. Many extracts are made from the private diary of the late 

 Nicolai Hanson, the naturalist of the 'Southern Cross' Expedition, who 

 died before the conclusion of the voyage. 2 The fourteen half-tone illus- 

 trations, from photographs of the Adelia Penguin rookeries, of the birds 

 singly and in groups, in various attitudes and under diverse conditions, 

 afford a most welcome contribution to the life-history of this exceedingly 

 interesting species. — J. A. A.
