Severtzoff’s ‘Fauna of Turkestan, 173 
under the name of Aigithalus castaneus, respecting which he 
writes as follows :—“ This species has been described by Prof. 
HKversmann as the adult male of 4. pendulinus (Est. Ist. 
Orenb. in. pp. 145-147) ;. but so far as I have ascertained 
from researches in Orenburg, the male of true 4. 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 A’. 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 At. pendulinus. Specimens obtained by Poéltzam near Astra- 
chan, 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 4. pendu- 
linus. As already stated, Dr. Severtzoff describes Agithalus 
coronatus under two names (44. atricapillus and A‘. coronatus), 
and 4i. macronyx also under two names (44. macronyx and 
44. rutilans) ; but it will be sufficient to give one description 
of each. His description of 4. coronatus (p. 1386) 1s 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-
