were in full plumage, with exception of two young birds and 
two males of Paradisornis rudolphi. 
As regards the calls of the Paradise-birds, the different 
species can only be approached by a knowledge of them, 
The birds are seldom seen, unless followed in this way, with 
the exception of P. raggiana in the low elevations. This 
species has a succession of loud notes which dominate the 
forest. Lophorhina superba has a shorter cry, but very harsh. 
Parotia sexpennis has a short sharp cry, which is almost 
exactly imitated by the natives, and it is thus easily 
approached. Drepanornis albertisi has several notes of a 
liquid quality, pleasant to hear. The cry of Astrarchia 
stephanie is a mere twittering. LEpimachus meyert has a loud 
deep cry, somewhat resembling the roll of a kettledrum. 
I have no distinct recollection of the call of the male Para- 
disornis rudolphi, but Anthony says that it resembles the 
note of a bell.

AuruoucH many collections of birds have been made in 
various parts of Australia during recent years, I think that 
I am right in saying that hitherto no ornithologist has ever 
visited the immense tract of land owned by the proprietors of 
the Alexandra station. This estate lies in the Northern 
Territory of South Australia and is, roughly speaking, situated 
about two hundred miles inland from the Gulf of Carpentaria 
in lat. 19° S. and long. 136° E. (See map, Plate IX.) 
In the year 1905 my father, Sir Wilham Ingram, arranged 
that Mr. W. Stalker, an experienced naturalist, should visit 
this locality with the object of making an exhaustive collec- 
tion of its birds and mammals—a task which has occupied 
him up to the present time. The mammals were presented
