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. 



Giildenstadt'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.
