skull by continually striking against the bars and sides o its den. Upon 

 a recent visit to the Earl of Derby's aviaries at Knowsley I saw specimens 

 of a male and female . . . which I believe to be the same as above ; 

 these, together with a female, said by Mr. Ogilby to have been exhibited 

 in the Surrey Zoological Gardens, some ten years since, are the only 

 specimens I have ever seen or heard of. 



The true RiippeH's colobus and the Angolan species also 

 figure in the list. 



Among the new birds were two king birds of paradise, the 

 first brought alive to Europe, the PhiHppine hornbill, the 

 golden - throated barbet, a number of parrots, the Andaman 

 banded crake, and the Soudan crowned crane, which was 

 also new to science.^ 



Two young female gorillas were purchased on August 19, 

 but they were not in good health when they arrived; Venus, 

 the larger animal, died before the end of the month, and 

 Chloe on September 15. In both cases dysentery was the 

 cause of death. The skins were sent to Tring Museum. 



There is little of importance to chronicle about the births 

 in 1901 ; but in the following year a brindled gnu calf was 

 thrown, and there was a litter of red river-hogs. In neither 

 case was it the first occurrence of the kind ; but both are 

 worth mention. Much more important was the birth of an 

 elephant calf, the first instance in the Gardens. The dam 

 belonged to Messrs. John Sanger and Sons, and was deposited 

 by them on September 19, 1901. The young elephant, though 

 of full term, was dead when found by the Assistant Super- 

 intendent.f 



Losses by death were heavy, and included the giraffe and 

 proboscis monkey already mentioned, and a Grevy's zebra. 



A hybrid waterbuck, between the West African sing-sing 

 {$) and the common waterbuck ( $ ) was born in October, 

 1903. In colour it favoured the dam, but there was prac- 

 tically no trace of the elliptical white rump mark, probably 

 indicating reversion to the original colour. 



The fine well-grown Polar bear, which had been a public 

 favourite, died suddenly on November 1. Mr. Salaman's post- 

 mortem showed that the cause of death was the rupture of
