LANIUS MINOR. 



The Lesser Grey Shrike is very common in the Caucasus 

 up to 4000 feet. 



LANIUS HOMEYERI. 



This form of the Great Grey Shrike is occasionally found 

 in the Caucasus. It is an intermediate form between L. ex- 

 cubitor and L. leucopterus. It should bear the name of L. 

 excubitor-leucopterus, inasmuch as these two forms are con- 

 specific^ a complete series from the western to the eastern 

 form being found in the intermediate localities. The frontal 

 band is grey (being black in the former and white in the 

 latter forms). In L. excubitor the rump and upper tail- 

 coverts are grey. In the intermediate form the rump is white 

 and the upper tail-coverts are grey, whilst in L. leucopterus 

 both are white. The white at the base of both the primary 

 and secondary quills and at the base of the tail is considerably 

 more extended in the Caucasian bird than in L. excubitor, 

 and considerably less so than in L. leucopterus. 



PARUS MAJOR. 



The Great Tit is found throughout the Caucasus up to the 

 limit o forest-growth. 



PARTIS PH^EONOTUS. 



Blanford's Cole Tit is found at Lenkoran. 



PARUS MICHAILOVSKII. 



Michailovsky's Cole Tit is a new species described by Bog- 

 danow from skins obtained by Michailowsky on the pass of 

 Suram, the pass of Zacarsk, and Abas-Touman. Bogdanow 

 also saw it near Veden. It is an intermediate form between 

 P. phceonotus and P. ater ; and future researches will probably 

 prove that these two forms are conspecific. An example 

 measures wing 2'65 inches, tail 2, culmen -44, tarsus *7. 

 The upper parts are slate-grey, suffused with green, making 

 an olive-brown yellower than that of P. ph&onotus, and show- 

 ing the slate-grey when the plumage is disturbed. The under - 

 parts scarcely differ from those of P. ater.
