Severtzoff's 'Fauna of Turkestan.' 173 



under the name of yEgithalus castaneus, respecting wliich 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 j^. 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 ^. 2Jendu- 

 linus, but smaller in size. Eversmann says that the dark 

 marking on the cheeks extends over a smaller area, and tlie 

 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 ^. pendulinus. Specimens obtained by Poltzam near Astra- 

 chan, and now in the Kazan Museum, all agree in having the 

 (;rown 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 /E. pendu- 

 linus. As already stated, Dr. Severtzoff describes Mgithalus 

 coronatus under two names {JE. atricapillus and^. coronal us), 

 and ^. maci'onyx also under two names {jE. macronyx and 

 ^. rutilans) ; but it will be sufficient to give one description 

 of each. His description of ^. corotiatus (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 Avith 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-
