then turning upwards, nearly meeting at the occiput, the bill short and compact, 
and the middle toe and interdigital membranes quite black. In consequence 
of these dijSerences I had intended to characterise these birds as distinct from 
P. cequinoctialis under the name of P. conspicillata from the white markings 
of the head.” Though here stated to be abundant in the Atlantic, as above noted, 
all the specimens save one, I have seen were from Australian seas, and as Gould 
figured this form as the Australian bird in his Birds of Australia four years later, 
I have selected, as the type-locality for P. conspicillata, Australian seas. 
P. a, hrdbournei, subsp. n. ; west coast of South America. 
Breeding-place unkno™. Agreeing with P. a. steadi in having 
a white chin-spot, but larger throughout ; the colour of the bill 
in life not yet recorded, except by Solander, as below. Wing

This is the form described by Solander as ProceUaria fuliginosa as 
follows : —

The “Fig. Piet.” refers to Parkinson’s Drawing No. 19, which is merely 
a pencil drawing with the white interramal patch simply indicated b^ a line. 
Without any description to guide him. Gray concluded that the figure represented 
a bird without any white at all on the chin, and when he received such a bird 
from New Zealand he named it after the artist, ProceUaria parkinsoni Gray, 
and cited as equivalent this drawing (see under that species).
