1869.] MESSRS. SCLATER AND SALVIN ON MEXICAN BIRDS. 361 
The following papers were read :— 
1. On a Collection of Birds made by Mr. H. S. le Strange 
near the city of Mexico. By P. L. Scrarer, M.A., 
Ph.D., F.R.S., and Ospert Satvin, F.L.S. 
Mr. H. 8. le Strange, during his residence in Mexico, as attaché 
to the British Legation in 1865 and 1866, formed a considerable 
series of bird-skins, principally in the vicinity of the capital itself 
and in the upper parts of the valleys which fall towards the Atlantic. 
Mr. le Strange having kindly submitted this collection to our exami- 
nation, we have had great pleasure in determining the species con- 
tained in it (which are 262 in number), and beg leave to offer to 
the Society some notes on a few of the rarer species, made during 
our examination of the specimens. 
1. Piprto macuatus, Sw. Phil. Mag. 1827, i. p- 434. 
Three skins of this bird are in the collection. Mr. le Strange 
notes that it is found in the tierra fria, in the barrancas, aud that its 
Mexican name is “ Chalmero.”’ 
It seems to us very doubtful whether it will not be necessary to 
unite under this name Pipilo arcticus, Sw., P. oregonus, Bell, and 
P. megalonyz, Baird. The northern specimens are mostly blacker 
on the back; but a skin sent to Sclater by Prof. Baird as P. mega- 
lonyx trom South California, and another as P. arcticus, are not, in 
our opinion, separable from Mexican specimens. This bird descends 
as far south as the highlands of Guatemala, and was obtained by 
Salvin near Quezaltenango (‘ Ibis,’ 1866, p. 193). 
2. Prprto macronyx, Sw. Phil. Mag. 1827, i. p- 434, 
We have usually called the species in our collections Pipilo vires- 
cens, under which name it was described by Hartlaub, ‘Journ. f. 
Orn.’ 1863, p. 169. But upon referring to Swainson’s characters 
there can be no doubt that the same bird is his Pipilo macronyz. 
It is easily known from the preceding (P. maculatus) by the olive- 
green edgings of the back- and wing- and tail-feathers; but Mr. le 
Strange has not distinguished the two species in his MS.  Sclater 
has one of the original specimens of P. virescens in his collection, 
received trom Dr. Hartlaub, also examples collected by Boucard 
during his last expedition, and a skin obtained by Mr. White near 
the city of Mexico. 
3. PIpPILo FUSCUS. 
Pipilo fusca, Sw. Phil. Mag. 1827, i. p. 434, et Anim. in Men. 
p. 347; Bp. Consp. p. 487 ; Cab. J. f. Orn. 1862, p. 474. 
Pipilo mesoleucus, Baird, Pr. Ac. Phil. vii. p. 119, et B. N. A. 
p- 518; Sclater, P. Z.S. 1856, p. 304. 
There is no doubt that, as pointed out by Cabanis, the present
