sleeping), the nests with the single egg or young bird, the young in vari- 

 ous stages of growth, the adults in various acts and attitudes, the old 

 birds in the air leaving the rookery, a deserted rookery, etc. In addition 

 to this the various plumages of the young are described, the adult plum- 

 age, the changes in the form of the bill with growth, with a table of com- 

 parative measurements of old and young birds, showing the great rela- 

 tive increase in the length of the tarsus in the old as compared with 

 young birds. As a result we have laid before us in detail the life historv 

 of a species of which comparatively little "was previously positively 

 known. — J. A. A. 



Oberholser on Birds Collected in the Kilimanjaro Region, East 

 Africa.i — This collection, made by Dr. W. L. Abbott during the years 

 189S and 1899, comprises 256 species and subspecies, represented by 684 

 specimens. Most of the novelties had previously been described by Dr. 

 C W. Richmond in 1S95, the new forms broughtout in the present paper 

 numbering three species and six subspecies. In the course of the paper, 

 however, several new genera and ten new subgenera are proposed, since 

 in working up Dr. Abbott's collection Mr. Oberholser has incidentally 

 included considerable revisionarv work on several groups of East African 

 birds, and upon the nomenclature of other species. 



The collection was found to include a number of rare species, besides 

 extending, even at this late day, the known range of a number of others. 

 "The best idea," says Mr. Oberholser, "of the marvelous richness of this 

 collection of Dr. Abbott's is probably furnished by the subjoined list of 

 62 species and subspecies that were undescribed when obtained by him, 

 an exposition that is possibly of more than passing interest as indicative 

 of the great progress in African ornithology that the past eighteen years 

 have witnessed." — J. A. A. 



McGregor on Philippine Birds. — We are in receipt of two papers 2 by 

 Mr. McGregor, giving a further account of his ornithological work in the 

 Philippine Islands. The first relates to the islands Romblon, Sibuyan, 

 and Cresta de Gallo, and is based on two months spent in their explora- 

 tion in 1904 (May 25-July 21). Besides field notes on about 90 species,
