Birds of the Caucasus. 15 



PARUS CRISTATUS. 



The Crested Tit is doubtfully recorded from the Caucasus. 



PARUS C^RULEUS. 



A Blue Tit is common on both sides of the Caucasus ; but 

 as no specimens were brought home, it is impossible to say 

 whether it is of the European or the Persian form. 



PARUS BRANDTI. 



Brandt's Tit is described as new by Bogdanow from a 

 single example much injured in shooting. The measure- 

 ments are wing 2*52 inches, tail 2*1, culmen *38, tarsus '64, 

 which agree with those of the Marsh-Tit. The colours are 

 also those of that bird, except that there is no black on the 

 throat. I take it to be a young female of P. palustris. 



PARUS PALUSTRIS. 



The Marsh-Tit is said by Menetries and by Nordmann to 

 be found in the Caucasus; but recent travellers have not con- 

 firmed this statement. 



PARUS LUGUBRIS. 



The Sombre Tit is recorded by Nordmann from the east 

 shore of the Black Sea ; but no examples from the Caucasus 

 are known in collections. 



PARUS CAUDATUS. 



The Long-tailed Tit is recorded from the Caucasus both 

 by Nordmann and Menetries ; but recent travellers have not 

 obtained it. 



CALAMOPHILUS BIARMICUS. 



The Bearded Tit has not yet been recorded from the Cau- 

 casus ; but Bogdanow observed it in the reeds in the delta of 

 the Terek. 



^EGITHALUS CASPIUS, Pb'lzam, Proc. Kazan Nat. i. p. 141. 

 The Caspian Pendulous Tit appears to be very local in the 

 Caucasus. Bogdanow found it in the delta of the Terek. 



SAXICOLA ISABELLINA. 



The Isabelline Chat is common on the steppes of the 

 Caucasus.
