frame the governing features of a series from a given locality, and under 
the circumstances we must utilise a name. Though this may not meet 
with the approval of some workers who would dismiss all names as 
synonyms that they with a few birds cannot recognise, it is the only 
practical method of dealing with a problem such as is here seen. 
The first point of application is the fixation of Falco berigora Vigors and 
Horsfield, and the one fact certain is that it came from New South Wales. 
Though killed near the coast it is not the coastal form. The coastal New 
South Wales form is the one called Hieracidea orientalis by Sharpe. 
Gould’s I. occidentalis is the Western form resembling I. berigora Vigors 
and Horsfield, but it is smaller. We have now fixed three names to three 
recognisable forms, but the distribution is not so clear. 
I propose to use the name 
leracidea berigora orientalis Sharpe 
for the birds frequenting the coastal districts of South Queensland and New 
South Wales and practically the whole of Victoria. The description given 
by Sharpe may be taken as typical, though variation is great as commonly 
seen in Victorian birds. It is quite possible that were long series (and by 
long I here mean twenty, at least) adult nesting-birds from each locality 
carefully examined, Victorian birds might be separated as a race. 
For Tasmanian birds I propose the name 
leracidea berigora tasmanica, subsp. nov. 
a series I do not exactly correlate with Victorian birds though nearest 
those, and belonging to the I. b. orientalis series. It is absolutely necessary 
to make comparisons with series to distinguish this, and the real reason for 
separating it is to emphasize the fact that the orientalis form is found in that 
locality without any intermixture of the berigora phase. 
The description of the type may be given as follows : General colour 
above brown with buify tips to the feathers ; on the rump the feathers have 
spots or bars : the head darker, the feathers with black shaft-streaks. The 
upper wing-coverts are brown with obsolete bars of bufi. Primaries brown 
with bars of light buff on the inner webs : under aspect of primaries whitish. 
Tail-feathers narrowlv barred with buff. Throat and cheeks white, divided 
bv a black moustachial streak. Under-surface white, the feathers sometimes 
tipped with brown and the majority with dark shaft-streaks. Under wing- 
coverts buff. Thighs brown with obsolete bars ; under tail-coverts white. 
Wing 325 mm., tail 185, cuhnen 21, tarsus 65. 
A similar state of affairs occurs at Cape York. From Cairns northward 
along the coast only birds of the orientalis type occur, and the whole of the 
specimens recorded and procured from the Cape York Peninsula agree in this
