CAPE TOWN PALM COCKATOO. 
as examination of the results of Salvadori and Van Oort show these to be in 
agreement. 
Probosciger aterrimus macgillivrayi Mathews. 
Type-locality : Cape York, Australia. 
This subspecies is slightly larger than the typical form and may be 
blacker, as I thus characterised it, and in this feature Rothschild and Hartert 
and Ogilvie-Grant have concurred, but I am not definite on this point at 
present. My own series measures as follows : wing, <?<J, 357-361 mm. ; 
$$ 342-354 mm. These figures agree closely with those given by Ogilvie-Grant 
for British Museum specimens thus : wing, <£<£, 355-368 mm. ; $$, 335-341 mm. 
In connection with these I noted that all had the crest feathers very narrow, 
quite different from the crest feathers of typical birds, which are broad. 
Moreover, the narrowness is truly structural and has nothing to do with 
wearing, as suggested by Ogilvie-Grant in connection with Van Oort’s 
stenolophus. However, though my series shows male and female as well as 
immature, I do not understand this crest formation, as Ramsay definitely 
stated he had specimens from Port Moresby, New Guinea, showing both 
narrow and broad crest feathers, though observing that his Cape York 
examples had narrow crest feathers. 
Apparently the birds from the whole of New Guinea were lumped as one 
subspecies by Rothschild and Hartert and Ogilvie-Grant, but I would here 
recognise three, with the proviso that there may be many more. Thus : 
Probosciger aterrimus griseus (Bechstein) 
Type-locality : Sorong, North-west New Guinea. 
The birds from the Arfak Peninsula will bear this name, the synonyms 
of which I have already given. This would equal $. a. aterrimus Rothschild 
and Hartert, and S. a. goliath Ogilvie-Grant. I have named Sorong as the 
type-locality, as this place was the most accessible to early voyageurs ; and the 
birds from there, according to Salvadori, are larger than the Salwatti, etc., 
birds and were also quoted in connection with his var. major , a term 
introduced as equivalent to griseus Bechstein and goliath Kuhl. If birds 
from the eastern side of the Peninsula are separable, then the name 
salvadori Meyer might be available. It should also be noted that Van 
Oort suggested that the Island of Jobi in Geelvink Bay might be inhabited 
by a different subspecies. 
Probosciger aterrimus stenolophus (Van Oort). 
Type-locality : Humboldt Bay, 
North coast New Guinea. 
This name may be used for the birds from the North coast, which have 
narrower crest feathers than typical birds and are also larger. It would
