THE BIRDS OF AUSTRALIA. 
specimens fully equal in size to the larger examples from Australia do occur in 
Hew Guinea, while, on the other hand, specimens from Northern Australia are 
undoubtedly smaller than many of those from New Guinea.

“ This table shows that the Northern Australian specimens come near 
those from New Guinea in size at least ; we have accordingly recorded them 
as C. triton, regarding all these forms merely as belonging to one very variable 
species, which may or may not be divided into subspecies according to 
individual opinion.” 
The items of interest in the above details are the long bill of the Port 
Moresby specimen combined with small size, and the wing measurement of 
the Tasmanian specimens as contrasted with those of New South Wales and 
the comparatively longer bill. 
Van Oort, in Nova Guinea, Vol. IX., Zoologie, reporting upon birds from 
South-western and Southern New Guinea, recorded under the name (p. 70, 
1909) Cacatva galeritus triton (Teinminck) : “ Coll. Koch, $, Merauke. . . . Bare 
space round the eyes white.” A very small specimen, wing 260 mm. The 
white colour of the bare space round the eye is interesting. 
“ Coll. Lorentz 4$£’s 2 not sexed, Noord River. 
“ Mr. Lorentz did not note the colour of the bare skin round the eyes. The 
birds belong not to the largest ones ; the wings of the four females measure 
300, 298, 285, and 297 mm., those of the two not sexed 300 and 305 mm. 
The type-specimen of Psittacus triton Temminck, a female collected by 
S. Muller on Aiduma Island near the Triton Bay, measures 310 mm., and 
specimens in the Leyden Museum from Dore and the Karon District have a
