160 ÏALEGALLUS PYRRHOPYGIUS. 



him under the name of Talegallus fuscirostris on account 

 of the brownish color of their bill. Our specimens from 

 the Aru islands have like all others the bill yellow , although 

 Mr. von Rosenberg states in his manuscript that the bill 

 of these very same specimens when they were newly killed , 

 was of the same brownish color , shown by young birds 

 and which is gradually fading into yellow. Lastly , I wish to 

 mention that the Talegallus Arfaki of Salvadori is established 

 on a couple of newly-born specimens caught on the Arfak 

 range of mountains. 



It is , nevertheless , true , that there exists , in New- 

 Guinea , besides the Talegallus Cuvieri , a species very 

 different from all those mentioned in the foregoing lines. 

 The .skin of one single specimen of this apparently undes- 

 cribed species was recently brought to Europe by one of 

 the Dutch missionaries stationed on the eastern coast of 

 the North- West peninsula of New-Guinea. The large col- 

 lection from which I selected this skin, containing not 

 only birdskins from the mainland of New-Guinea , but also 

 from some of the islands of the bay of Geelvink , and not 

 being labelled , it will be the task of further investiga- 

 tors to point out the habitat of this bird in a more 

 special way. 



Our Talegallus pyrrhopygius , although presenting in 

 general the same coloring of plumage as Talegallus Cuvieri , 

 differs from this species by several so very conspicous 

 characteristics , that its comparative diagnose can be summed 

 up in the following few lines. 



Our bird is in all its dimensions somewhat smaller than 

 Talegallus Cuvieri. The bill is shorter, more rapidedly 

 bent downwards and of a brownish gray horn color, and 

 not yellow as it is commonly the case in Talegallus Cuvieri. 

 The legs , feet and claws are throughout of a brown horn 

 color, and show not at all the yellow tint of those parts 

 in the common species. The feathers of the neck and 

 the upper part of the throat are much more developed , 

 and more numerous. There exists , finally , a very striking
