serve, that the only specimen of the G. Papuensis in the Linnean 
collection, collected by Mr. Caley, is marked by that gentleman 
as a male; while a specimen of the G. melanops is noted as a 
female. ‘Time will clear away the difficulties that attend such 
points. At present we can only state the doubts which exist on 
the subject.

The bird described above exhibits so many points of distinc- 
tion from the preceding species, that we have ranked it as sepa- 
rate. Its locality also, which is different from that of the other 
species, serves to strengthen us in this opinion. The chief dif- - 
ference consists in the inferior size of our bird, all the specimens 
we have seen of the former species being about thirteen inches 
in length ; in the darkness of the ash-colour on the back ; in the 
narrowness of the frontal band, and particularly in the white 
colour of the mentum. There is, however, much variation, as is 
alleged, in the Grauc. melanops and Papuensis ; and it may hap- 
pen that our bird is but the young of one of those species.—Our 
specimen was found on the South Coast by Mr. Brown in 1803.
