Recently published Ornithological Works. 557 
obtained in Dahomey are added, making the whole number 
yet known 48. This is obviously but a very small part of 
the Dahomey an avifauna. 
92. Oustalet on the Birds of Cambogia, Laos, Annam, and 
Tonquin. 
[Les Oiseaux du Cambodge, du Laos, de 1’Annam et du Tonquin. Par 
M. E. Oustalet. Nouv. Arch. d. Mus. d’TIist. Nat. s<$r. 4, t. i.] 
An account of the birds of the eastern portion of the great 
Siamese Peninsula, those of the western side being com¬ 
paratively well known, was much wanted, and it is right that 
France, to whom the country mainly belongs, should under¬ 
take the task. M. OustaleCs memoir, now before us, is based 
on the rich collection of Indo-Chinese birds furnished to the 
National Museum of France by MM. Bocourt, Germain, 
Harmand, and many other contributors, commencing with 
Diard in 1824. It begins with the Parrots, of which 4 
species are known from that country, and then proceeds 
to the Diurnal and Nocturnal Birds of Prey. The Barbets, 
Woodpeckers, Cuckoos, Trogons, Hornbills, Kingfishers, 
Bee-eaters, and Boilers of Indo-China are also discussed in 
the first part, making altogether 78 species. Coloured plates 
are added of Picus ( Gecinus ) rabieri , Carpococcyx renauldi , 
Arboricola henrici , and Genneeus edwardsi, all remarkable 
novelties, the last two being given in advance of the suc¬ 
ceeding portions of this valuable memoir. 
93. Palmer on the Introduction of Noxious Birds. 
[The Danger of Introducing Noxious Animals and Birds. By T. S. 
Palmer. Beprinted from Yearbook of Department of Agriculture for 
1898.] 
The danger of introducing noxious animals and plants 
into strange countries is well known, and many examples of 
this evil practice are familiar to us. It is not the less 
necessary, however, that the general public, amongst whom 
are many with a rage for acclimatization/’ should be 
cautioned against it, and we are glad to see that the Agri¬ 
cultural Department of the U.S. has taken up the question.
