environs of the city of Mexico and thence southwards to La Parada and the highlands 
of the State of Vera Cruz. Westwards of the plateau it is found near Patzcuaro and 
Morelia, and in the Sierra Madre of Sonora. It has also been found at El Paso, and 
thence northwards to Utah and Nevada, and also in most of the country lying to the 
westward of the Rocky Mountains. Dr. Coues speaks of #. obscurus as migratory in 
Arizona, arriving in March or April and leaving in October. Some further valuable 
notes on this bird will be found in his ‘ Birds of the North-West,’ which we have no 
space to transcribe here. Mr. Henshaw says it is an abundant species in many localities 
in the middle and southern regions of the United States, though in others it appears to 
be absent. In summer it is a bird of the mountains, resorting to the deciduous trees 
and bushes on the banks of streams, or, as in Arizona, the oaks. In other places it is 
found in the barren pine-clad hills where there is no deciduous vegetation. In the 
autumn it leaves the hills and may be met with in its journey southwards wherever 
trees and bushes afford it suitable shelter 1° 
The nest is placed in aspen bushes, and is, like that of EZ. minimus, compactly felted, 
cup-shaped, composed chiefly of greyish fibres, and placed in a fork of an upright branch 
of a bush or small tree. The eggs are plain buffy-white.

Swainson’s name 7yrannula affinis was given to a bird in Bullock’s collection, stated 
to have been obtained in the “ maritime parts of Mexico.” Various attempts to recog- 
nize this name have been made. Mr. Sclater, in 1859, thought it possible that it might 
refer to the bird he was then describing as Mitrephorus phwocercus; and, in 1866 (Proc. 
Ac. Phil.), Dr. Coues thought that his MW. pallescens was perhaps meant. It was not 
until 1882 that Salvin examined Swainson’s type and identified thereby a specimen 
from Cinco Sefiores in Mexico in the Strickland collection at Cambridge, and referred 
to it Mr. Lawrence’s L. fulvipectus. We have since compared the Strickland bird with 
a specimen compared with Mr. Lawrence’s type, so that our identification of F. fulvi- 
pectus is hardly open to question. Unfortunately this identification has been entirely
