210 Address delivered at the sixth and last 
honour of the first observer. ‘The two last-mentioned birds 
are closely allied to a species which had been some time pre- 
viously made known to science by Mr. Menzies’s researches in 
California, the Pérdix californianus of Dr. Latham, and form 
an interesting addition to a group which represents in Ame- 
rica the Quails of the Old World. It may not be here out of 
place to mention that specimens of two species of the group, 
the Ort. californianus and Douelasz7, are at present living 
in the gardens of the Zoological Society. ‘The same gentle- 
man has added considerably 1 to the information which we had 
already possessed of the habits and economy of some of the 
scarcer Gallinaeeous Birds of North America; more particu- 
larly of the 7étrao Urophasianus, which we may well remem~ 
ber to have seen first exhibited and described in this room by 
our distinguished friend and correspondent, the Prince of 
Musignano. Mr. Douglas has also published i in the Z0ologi- 
cal Jour nal some interesting details respecting the economy 
of the Valtur californianus. 
We are all well aware of the rare ornithological treasures 
contained in the collection of Mr. Leadbeater. We have to 
congratulate ourselves that many of these are becoming known 
to science through the exertions of their owner. His liberality 
hitherto to naturalists, i in opening his collections for their use, 
is well known; his ability in making use of them hinself for 
the advantage of science is now equally conspicuous. In the 
last number of the Linnean Transactions he added some 
species to the rare genera Phyt6toma, Indicator, and Curso- 
rius; a beautiful species to the Tyrannulus of M. Vieillot ; 
and an African species to the group of Pardalotus, which had 
previously been supposed to be confined in its range to Aus- 
tralia. ‘The same volume affords a treat to the lovers of the 
more splendid productions of nature, in the description by the 
same hand, and accompanying representation, of a magnificent 
pheasant, the Phasianus Amhérst7@. From the same collec- 
tion we had an opportunity of seeing at our last meeting some 
additional novelties, which will shortly be described by their 
owner, more particularly two interesting species of the Psitta- 
cide, belonging to the Australian groups ‘Trichoglossus and 
Platy céreus. 
The commanders of our scientific expeditions, for the last 
few years, have not neglected the opportunities afforded to 
them of contributing to our stores of zoology. The valuable 
ornithological collections which were obtained by Captain 
Beechey, in his late voyage in the Blossom, more particularly 
on the north-west coast of America, were sent to me, within 
the last year, for examination. Twelve species, apparently
