ORNITHOLOGY OF QUITO. 
48 only were met with, and 25 species being common to both 
aspects, it follows, that on the eastern, 252 only are peculiar- 
20 only to the western slope. 
D’Orbigny has thrown these observations into a table, which both 
exhibits his views of the classification of the “ Passeraux,” as well 
as the numbers of species and distribution of genera according to 
latitude and elevation. The preceding summary, with a copy of 
this table on the opposite page, we consider may be interesting, 
when commencing observations on the ornithology of a region, 
situate in continuation with that to which his remarks refer; and 
we only regret, that his observations, on distribution and migra- 
tion, run to such a length as would much exceed our limits. We 
may, however, have again to recur to them. 
The species which we have received in this small collection are— 
Cotinga arcuata , De Lafresn. — “ From the forest on the western 
side of Pichincha ; inhabits the cold region.” 
Tcenioptera alpina , Jard. — “ This species occurs on the highest 
ridge of the Andes, rarely descending below the snow.” — (See 
Plate and Description.) 
Phrygilus unicolor , De Lafresn. — “ On the elevated pastures 
of the Andes, 13,000 to 14,000 feet.” — (See Plate and Descrip- 
Pichincha; frequenting sides of streams.” 
Diglossa cyanea , De Lafresn. — “ From the forest on the 
eastern side of Pichincha; in the cold region.” 
Trochilus ensiferus . — ££ Humming bird ; occurs on Pichincha, in 
the shrubby region, 11,000 to 12,000 feet above the sea level.” 
We would wish much to ascertain the habits of this most remark- 
ably formed species. The length of the bill equals that of tie 
whole bird, and must be suited to some noonW W,;i nr mode of 
tion.) 
Limnornis, 
From the lofty pastures of 
“" co “ l,,e Anaes i to 14,000 feet of elevation.”
