Distribution of Birds in North Russia. 209 



(31) Phylloscopus collyhita (VieilL). No. 141 in Tables. 



For reasons before given when treating of the Northern 

 Division, it seems desirable that specimens of the Chiffchaff 

 obtained m N.W. Russia should be carefully compared with 

 type specimens of P. tristis, as there is a possibility of confu- 

 sion existing between the two species. The probability is, 

 however, that the former does occur in West Russia, reaching 

 to perhaps 63° or 64° N. lat., but that specimens occurring 

 further north than that belong to the Eastern species. Vide 

 Part II. of this paper, ' Annals,' July 1877, p. 24 ; Lilljeborg, 

 p. 273 ; and Mejakoff, p. 630, who gives it (under tlie name 

 Ficedula rufa, Lath.) as rather rare even in the south of the 

 government in the South-central District. SabanaefF (No. 22) 

 considers this statement of MejakofF's as strange ; but the 

 species found by Meves east of Moscow was P. tristis, not 

 P. collyhita, which is the one Sabaniieff includes. 



(32) Regulus lyroregxdus, Pall, No. 146 in Tables. 



The only record I find is Sabanaeff's, the bird from which 

 Meves described his Phyllopneuste Middendorfii and figured it 

 (8) being in the Petersburg Museum from Ochotsk. It is 

 numbered 58, however, in Meves's list (p. 758), which is apt to 

 mislead ; and the same remark applies to his No. 59, also only 

 seen in the Museum, and one or two more, which were better 

 included under " Observations." 



(33) Troylodytes parvulus, Koch.. No. 148 in Tables. 



Said by Sabanaeff (22) , on the authority of a native, to occur 

 at Ijma (64° N.), where it is known by the name "p/sfa." I 

 consider that more proof is wanting. Dresser says his col- 

 lector at Archangel reports it as occurring there in summer; but 

 I doubt it. 



(34) Columba aenas, L. No. 167 in Tables. 



Although recorded as occurring at Onega Sea (Kessler) 

 and quoted by Meves (8), Sabanaeff (22) appears to doubt 

 whether it really occurs in the S.W. District. 



(35) Cohtmba turtur, L. No. 169 in Tables. 



Barely establishing itself upon the southern boundary of our 

 present division, Mejakoff doubting whether it goes further 

 north than 60° N. lat. (No. 19, p. 632), and his being the 

 only record I can at present find of its occurrence in the S.W.
