G. nigricollis, and G. monachus are deficient. I specially admired 

 a fine pair of Anthropoides leucauchen. On the Stork-and-Heron 

 side of the building I noticed amongst the former a splendid 

 specimen of Ciconia boyciana, a Tantalus loculator ; and amongst 

 the latter a fine specimen of Ardea sumatrana, also A. goliath, 

 A. cocoi, &c. In the same house were specimens of Chwuja 

 burmeisteri and of Cariama cristata. 



In the neighbourhood of the Crane-house a new building for 

 small birds, Parrots, &c, has been erected. For the present 

 only one half of this building, which is eventually to consist of 

 two houses with a large " flying aviary " between them, has been 

 completed. In the above-mentioned aviary the background is 

 formed by a nicely laid-out rockery, whilst large trees and a piece 

 of water help to make it a favourite resort for the birds. It 

 contains a large number of Waders of different species, some 

 Mergansers, and quite a colony of Herons and JVight-herons, which 

 breed in the large trees. Of special interest were three hand- 

 reared Ospreys (Pandion haliaetus), which flew about the aviary 

 without being noticed in the least by the numerous small Waders 

 and Gulls and other birds. Dr. Heck told me that this had been 

 the case from the beginning, the birds probably knowing that the 

 fish-eating Ospreys have nothing in common with the dangerous 

 Birds of Prey. It was rather a curious sight to see one of these 

 Ospreys swim in the little pond between the Smews in a very 

 duck-like fashion. Amongst the "Waders u as a pretty group of 

 Himantopus nigricollis. In the house itself was a large collection 

 of birds, mostly exhibited in small cages in long rows, one over 

 the other. Some of the more delicate birds were kept in glass 

 cages with tops of wire and with a special heating-apparatus 

 under the cage, a system which seemed to answer extremely well. 

 On the whole I think the cages were in most cases too small, but 

 thanks to the cleanliness and to the great* care bestowed on the 

 birds, they appeared generally to be in extremely good health and 

 plumage. 



Amongst the Parrots exhibited I saw examples of seven species 

 of Palceornis, including a splendid pair of the large P. derbianug 

 from Southern China, which I have never seen elsewhere ; examples 

 of fourteen species of Cockatoos (amongst them a splendid Micro- 

 glossus aterrimus) ; Nestor notabihs and N. meridionalis ; ten species 

 of Macaws, with Ara hyacinthina, A. leari, A. glauca, A. spixi, and 

 the rare A. ambigua in the number ; twelve species of Platycercus 

 and its allies, including P. multicolor, P. hcematonotus, P. browni, 

 and Polytelis alexandrw ; also Pyrrhulopsis personatus. Besides I 

 found such rare birds as Henicognaihus leptorhynchus, Pyocephalus 

 versteri, Pionopsittacus pileatus, Pionias chalcopterus, C'hrysotis kecki, 

 C. xanihopteryx (being the Paraguayan form of C. asttiva, with 

 yellow wing-bend), and NympMcus uvoeensis. The whole collection 

 of Parrots includes examples of 136 species. 



The Picaria? present many interesting species, including four 

 Toucans, two Aracaris, and six Hornbills, also Touracous (Turacus
