conjunction with Dr. Murie."^ One of the most important pieces 

 of work in this decade is that on the Classification of Birds 

 by Dr. Gadow, which was published in the volume for 1892. 

 This was merely a summary of the author's view, given the 

 following year in full, with some slight modifications in 

 Bronn's " Thier-Reich."t In 1893 the Secretary's revision of 

 the monkeys of the genus Gercopithecus appeared. Next year 

 Mr. Coryndon's account of his expedition to procure museum 

 specimens of the white rhinoceros was published. Notes on 

 the Nursing Habits of some South American Tree Frogs by 

 Dr. Goeldi and Mr. Boulenger in the volume for 1895 are of 

 interest. The deposition of eggs and the carriage of tadpoles on 

 the back are probably to be explained in the same way as in 

 the Surinam toad, to which reference has already been made 

 (pp. 213, 214), with a citation from Bartlett's account in the 

 volume for the year next following. In 1896 Mr. Bateson 

 exhibited some pigeons showing webbing between the toes. 



Mr. de Winton's paper on the Existing Forms of the Giraffe, 

 in 1897, is noteworthy, as are later contributions of his on the 

 Moult of the King Penguin. In 1897 also appeared the first 

 of Mr. Graham Kerr's contributions on Lepidosiren, and Mr. 

 Moore's paper on the Zoological Results of the Tanganyika Ex- 

 pedition. Mr. Oldfield Thomas described, in 1898, a new sub- 

 species of the giraffe, from West Africa.^ The volume for 1899 

 contains an interesting note by the Secretary on two musk oxen 

 at Woburn, probably the first to reach Europe alive ; and Mr. 

 E. N. Buxton's account of his visit to the forest of Bielovege, 

 where the European bison are preserved by the Czar. The 

 papers on the giant ground sloth of Patagonia, by Dr. Moreno 



* Inasmuch as the subject — the African rhinoceros — died of cancer in the 

 stomach, the space (a little over a page) devoted to the morbid anatomy cannot 

 be considered excessive. There is no reference to the present whereabouts of the 

 preparations. 



t Whether the upshot of it all has been to establish a Natural Classification, 

 one indicating the true descent, and the real affinities of the several groups known, 

 time alone will show ; but that this latest attempt has been made according to the 

 best method few will doubt. — Newton : " Dictionary of Birds," Introduction,
