[The female specimen above referred to, which was obtained 

 at Objimbinque on the 10th March, 1865, was presented to 

 me by Mr. Andersson, and was added to the collection of Rap- 

 torial birds in the Norwich Museum. Amongst the skins of 

 birds left by Mr. Andersson at his decease was the male specimen 

 which he subsequently obtained ; and this, on the sale of his 

 collection, was secured for the British Museum, in the ornitho- 

 logical gallery of which it is now exhibited. These two specimens 

 only differ from each other in the somewhat smaller dimensions 

 of the male bird. The female example was described by me in 

 the ' Proceedings of the Zoological Society ' for 1865, under the 

 belief that it was both generically and specifically new, and I 

 suggested for it the name of Stringonyx Anderssoni. 



Mr. A. D. Bartlett very obligingly undertook to mount this 

 specimen for the Norwich Museum ; and whilst the bird was thus 

 passing through his hands, it occurred to him that it certainly 

 belonged to the same genus, and probably to the same species, 

 as a bird in the Museum at Ley den, which had been figured and 

 described by Mr. G. F. Westerman, under the name of Machae- 

 rhamphus* alcinus, in the first volume of a scientific work pub- 

 lished at Amsterdam under the title of ' Bijdragen tot de Dier- 

 kunde, &c/ This specimen had been purchased for the Leyden 



* Equivalent to MachcBrhampJnis in the type used by English printers.
