above. The closing year of the decade saw the publication of 
Volume 168 of the Philosophical Transactions of the Royal 
Society of London, containing an article by Dr. Richard 
Bowdler Sharpe on the birds of Kerguelen Island, with field 
notes by Rev. A. E. Eaton, and a shorter article by Mr. How- 
ard Saunders on the birds’ eggs obtained on that island. In 
1881, Mr. Osbert Salvin published in the Voyage of H. M. S. 
Challenger, Zoology, Volume II, his final report On the Pro- 
cellarude collected during the Expedition; twenty-three spe- 
cies being noticed. In Volume IV of the same publication, 
followed Mr. William Alexander Forbes’s Report on the 
Anatomy of the Petrels (Tubinares) collected during the 
Voyage. The year 1887 was marked by the appearance of 
Mr. Robert Ridgway’s Manual of North American Birds, in 
which most of the species of the Order Tubinares were con- 
sidered. In 1888, Sir Walter Lawry Buller brought out Vol- 
ume IT of the second edition of his illustrated History of the 
Birds of New Zealand, with its life histories of numerous 
Tubinarine species. The same year Mr. Osbert Salvin con- 
tributed in The [bis a third instalment of his Critical Notes on 
the Procellarude, foreshadowing the close of the Couesian 
Period.

The advent in 1896 of the twenty-fifth volume of the Cata- 
logue of the Birds in the British Museum, embracing Mr. 
Howard Saunders’s monograph on the “Gaviz (Terns, Gulls, 
and Skuas)” and Mr. Osbert Salvin’s monograph on the 
“Tubinares (Petrels and Albatrosses),’”’ ushered in the Sal- 
vinian Period. With far greater facilities than those at the 
command of his predecessor, Mr. Salvin was able to simplify 
the whole subject and give it a new impetus. The shortcomings 
of this monograph, as in the preceding one, were due chiefly to 
lack of specimens and outdoor observation. 
The year 1901 witnessed the publication of Mr. Archibald 
James Campbell’s Nests and Eggs of Australian Birds, and 
1905 Sir Walter Lawry Buller’s Supplement to the Birds of 
New Zealand, each containing life histories of numerous antip-
