Severtzoff’s ‘ Fauna of Turkestan / 178 
under the name of JEgithalus castaneus, respecting which he 
writes as follows :■—“ This species has been described by Prof. 
Eversmann as the adult male of JE. pendulinus _ (Est. 1st. 
Orenb. iii. pp. 145-147) ; but so far as I have ascertained 
from researches in Orenburg, the male of true JE. pendulinus 
is very different. The present species has the forehead, cheeks, 
and sides of the head dark-coloured; crown, nape, and down 
to the back chestnut-red, becoming paler towards the rump, 
where it is greyish brown; otherwise coloured as zE. pendu¬ 
linus , but smaller in size. Eversmann says that the dark 
marking on the cheeks extends over a smaller area, and the 
crown is greyish in the female. But does he mean greyish 
brown or true grey ? for in the latter case it would be a female 
of JE. pendulinus. Specimens obtained by Poltzam near Astra¬ 
khan, and now in the Kazan Museum, all agree in having the 
crown and nape chestnut; but the sexes of none are marked.” 
I have a very good series of the present bird, and con¬ 
sider it an excellent species, quite distinct from JE. pendu¬ 
linus. As already stated, Dr. Severtzoff describes JEgithalus 
coronatus under two names (JE. atricapillus and JE. coronatus ), 
and JE. macronyx also under two names (JE. macronyx and 
JE. rutilans); but it will be sufficient to give one description 
of each. His description of JE. coronatus (p. 136) is as fol¬ 
lows :—“ Forehead, sides of the head, both above and below 
the eye, a portion of the nape and hind neck black; some of 
the nuchal feathers tipped with white, and a small spot on 
the centre of the crown is also yellowish white; below the 
dark portion of the neck is a brownish white collar, and below 
this, again, a band of chestnut; rest of the upper parts brown¬ 
ish grey; upper tail-coverts whitish, with broad dark greyish 
fawn-coloured shaft-stripes; upper part of the throat pure 
white; lower throat, breast, and flanks marked with rust- 
coloured spots, which are paler on the flanks; abdomen pale 
brownish ; under tail-coverts white, marked with greyish 
stripes ; lesser wing-coverts pale brownish, with a yellow 
tinge; the larger coverts black, with brownish white tips, 
externally broadly margined with chestnut-red, so that when 
the wing is closed the darker portion of the feather is con-
