ORNITHOLOGY OF SECTION D, 1850. 
Of the above, I consider the Tanysiptera, Syma, Drymodes, and 
Carpophaga, to be new to science, while the remainder have been 
described as pertaining to the Fauna of New Guinea, and I have 
accordingly characterized some of these at the meeting of the 
Zoological Society, held on the 23d of July. I find I haye omitted 
to mention, that among the birds sent home by Mr. M’Gillivray, 
on a former occasion, were a very fine pair of Rifle Birds, which 
he considered to be identical with the old Ptilorhis paradiseus, 
but which, had he had examples of the latter bird at hand to coml- 
pare them with, he would at once have seen was distinct. This 
very beautiful species I have had the high honour of dedicating 
to our amiable and excellent sovereign, under the appellation of 
Ptilorhis victorie. It will be seen, therefore, that the Australian 
Fauna is graced by no less than three species of this very beautiful 
genus, viz.— 
Ptilorhis magnijicus, victorie, paradiseus. 
“ You will oblige me by comparing the Chlamydera, from Cape 
York, with the other members of the genus, as I have a strong sus- 
picion that it may be different. I shot it while playing about 4 
bower. I have sent it to the British Museum.” 
I haye complied with Mr. M‘Gillivray’s wish, and find the bird to 
be quite distinct, both from C. nuchalis and C. maculata, and have 
accordingly named it cerviniventris, from the colouring of the ab- 
domen. Thus we have no less than four different species of birds 
inhabiting Australia, having the peculiar habit of constructing 
bowers or playing places, viz.— 
Ptilonorhynchus holosericeus. 
Chlamydera nuchalis, maculata, cerviniventris. 
“« After I wrote to you from Moreton Bay, May 19, 1849, we 
sailed to the northward for Rossel Island, the easternmost extreme 
of the Lonisiade archipelago, which runs west for several hundred 
miles, until it joins New Guinea. We followed the Bramble 
through an opening in the barrier reef surrounding the group, and 
anchored in what is called Coral Haven. Here the survey commenced 
in longitude 153° 16’ E., and latitude 11° 18 §. The natives 
were at first shy and suspicious; afterwards we had much com-
