Birds of the Caucasus. 17 



esting discoveries recorded in the volume. Hitherto this 

 species has only been known in collections from the single type 

 specimen of R. erythroprocta, Gould, in the British Museum, 

 obtained at Erzeroum. I examined several skins in the Mu- 

 seum of St. Petersburg ; and Bogdanow informed me that 

 others were in the museum at Kazan. There can be no doubt 

 that the Motacilla ochrura of Gmelin from the Persian moun- 

 tains is Gould's Redstart (abdomine flavo), and not the 

 Black Redstart, to which 1 have erroneously assigned it in 

 the ' Catalogue of Birds/ v. p. 339. 



RUTICILLA ERYTHROGASTRA. 



Guldenstadt's Redstart was originally described from the 

 Caucasus, but appears to be rare there, since no recent tra- 

 veller, except Radde, has found it in that locality. 



ERITHACUS HYRCANUS. 



The Persian Robin breeds in the Caucasus. 



ERITHACUS RUBECULA. 



The Robin is also found in the Caucasus. I have an ex- 

 ample in my collection obtained by Michailowsky. 



ERITHACUS SUECTCUS (Brehm, nee Temm.). 

 The Red-spotted Bluethroat passes through the Caucasus 

 on migration. 



ERITHACUS GOLZII. 



The Persian Nightingale is said by Menetries to be com- 

 mon in the forests of the Caucasus. Examples collected by 

 him are in the Museum at St. Petersburg. Bogdanow con- 

 siders its song not nearly so fine as that of our bird. 



ERITHACUS PHILOMELA. 



The Eastern Nightingale is said by Nordmann and Mene- 

 tries to be found in the Caucasus ; but their statements re- 

 quire verification. 



ACROCEPHALUS TURDOIDES. 



The Great Reed- Warbler is common in suitable localities 

 in the lowlands of the Caucasian district.
