consent of naturalists in congress assembled, would be a work 
worthy of the century. Let ornithologists be the first in the 
field, and the other -ologists will soon follow.” 
“ The Cockatoos puzzle me greatly. You make my Lombock 
sp. C. cequatorialis, which Temminck says is peculiar to N. Gilolo 
and N. Celebes. Do you make it a synonym of C. sulphurea, 
which you do not mention?* You will see small specimens of a 
Cockatoo from Mysol, which I thought were C. cequatorialis. I 
have just received a very small specimen from Gilolo, bearing the 
same relation to C. cristata that C. sulphurea does to C. triton. 
It will be, I suppose, quite new.” 
“ The larger and smaller specimens of Megapodius from Mysol 
are also curious. In colour they are exactly alike ; but the size 
of the bill and feet is so different that they must be distinct. 
Between the Trichoglossus of Amboyna and Ceram and that of the 
Papuan Islands I can discover no difference, and I suspect that T. 
nigrigularis of G. 11. Gray must be suppressed. You have left 
out Lorius domicella altogether from your list, giving L. tricolor 
to Amboyna in its place, which latter is wholly Papuan. Eos 
cyanostriata is a native of Timor-laut; and of Eos reticulata and 
squamata I saw nothing in Amboyna and Ceram, and believe 
they do not exist there. Aprosmictus amhoinensis is a species 
strictly confined to Ceram, which you have not given. It is 
quite distinct from the A. dorsalis of New Guinea. The Psitta- 
cidce of the Solomon Islands seem so exactly representative of 
those of New Guinea and the Moluccas, as to show that they 
must be included in the Papuan subregion, and (if true Lories 
are not found in New Caledonia) will mark its eastern limits. 
New Ireland and the eastern parts of New Guinea no doubt 
still contain many fine things in this group.” 
The last letters received by Mr. S. Stevens from Mr. Wallace 
are dated Delli in Timor, February 6th, 1861, and state that he 
had been there a month, and intended waiting two more. The 
country was barren, and, Australia-like, poor in insects; but 
birds were tolerably abundant, though not of very fine species. 
* No. C. sulphurea is certainly separable, and it is probable that the 
Lombock bird belongs to this form; the Timor species being, according to 
Temminck, the true C. sulphurea. —P. L. S.
