THE BIRDS OF AUSTRALIA. 
I also stated that the north-west form was easily separable and therefore 
recognised Gould’s dumetorum. 
While this species has been recognised from Timor, it has not been recorded 
from Java, so still there appears to be some confusion which, however, cannot 
be cleared up at the present time. 
I concluded : “ I have not seen any extra- Australian specimens which 
can be confused with either G, dumetorum or C, variolosus,^^ and this still holds 
good. 
The recognisable subspecies have not been well determined. I added 
C. westwoodia in 1913 three months later in publication to Dodd’s C. lineatus. 
I recognised that my form was a subspecies of the present, and so relegated 
it in my List, where I attributed Dodd’s G. lineatus from the description to 
the Fan- tailed species. Since then I have received Dodd’s type, and find that 
it is an immature of this species, and, moreover, is in so close agreement with 
the type of variolosus that it could be almost mistaken for it. From MelviUe 
Island Rogers sent birds showing both dark and pale under-surfaces procured 
on the same day. It is possible that two races may converge here and diverge 
again, as only the dark form was sent me from Parry’s Creek, North-west 
Australia. It seems unwise to further complicate the nomenclature in view 
of the doubt regarding the exact type locality of pyrrophanus, so that I 
conclude it wiU be best to allude to all the north-west birds from Parry’s 
Creek to Melville Island and Port Essington as 
Gacomantis pyrrhophanus dumetorum (Gould). 
Tlie southernmost form, which is fecund in South Queensland, New South 
Wales, and Victoria, wiU bear the name 
Gacomantis pyrrhophanus variolosus (Vigors and Horsfield). 
The birds from Normanton to Cairns will be caUed 
Gacomantis pyrrhophanus lineatus (Dodd). 
I now propose 
Gacomantis pyrrhophanus vidgeni subsp. n. 
for the smaU Cape York form, differentiated by MacgiUivray as being smaller and 
laying a different type of egg, and it is also paler than the preceding. The 
type is a male coUected by W. Maclennan at Cape York on the 17th of April, 1912. 
Probably many forms wiU later be separated in New Guinea, whence the birds 
have been caUed G. assimilis (Gray) which was given to an Aru Island bird. 
The complexity of the problem is so clearly seen in Australia that series are 
necessary to determine the races, but when such are at hand the solutions are 
comparatively easy.
