Australian Birds in the Collection of the Linnean Society. 301 
further from that gentleman, we find that his suspicions were 
founded merely on the circumstance of his having met with all 
these birds in the same place and at the same period. Although 
we have some doubt respecting our C. incertus being a distinct 
species, we have little respecting the present bird, which seems 
to belong to a different section of the genus from that in which the 
preceding species are included. The wings are shorter and more 
rounded, the tail also shorter and less graduated, and the ¢arsi are 
more naked and more elevated. There are six or seven species 
of Cuculus belonging to Australia and Africa, which form part of 
the same section of the group, and which differ from the bird 
before us only in their colours being bright and metallic. It is 
the want of these colours chiefly that causes us to consider the 
specimen before us as a young bird. In its general structure 
it has the characters of the birds to which we allude, and which 
in their young state are also without the shining tints of the 
adult birds, although perhaps g not so decidedly s so as our present 
Fail a 
species. 
Mr. Caley informs us that he met with the three last-described 
species in the neighbourhood of Paramatta. They frequented 
the green wattle-trees which were of low growth. They made 
their appearance on the approach of winter; and it was Mr. Ca- 
ley's opinion that they migrated southerly at the commence- 
. ment of spring.
