(29) {Phylloscopus collyhita, Vieill.) No number. 



I find records of this species by Lilljeborg and Goebel 

 unsupported by other evidence of its occurrence so far north. 

 Mejakoff gives it as rather rare even in the south of the 

 Vologda Government * ; but Meves gives it as tolerably com- 

 mon in the S.W. District. I consider its occurrence in the 

 North EEN Division very doubtful. 



Lilljeborg's description is too vague for purposes of satis- 

 factory identification, but seems to me more nearly to answer 

 to that of P. tristis, which species is more likely to occur 

 there in autumnal migration than P. collyhita. In Norway 

 the latter has been recorded as far north as 67° N. lat. (Col- 

 lett, 1876) ; but I cannot find any record of its occurrence in 

 the north of Finland. Goebel records " P. rufa " three times, 

 and mentions having once found the eggs ; but there is nothing 

 in his records to satisfy us that they should not have been 

 applied to another species. I have concluded, then, to place 

 P. collyhita in brackets and to place a ? opposite P. tristis in 

 the column for the N.C. District. 



(30) {Phylloscopus sihilatrix (Bechst.) .) No number. 



I cannot now find any specimens of this species in our col- 

 lections from Archangel, although Alston and I recorded its 

 occurrence in 1873 ; nor can Alston apparently now corroborate 

 our record. I therefore enclose it in brackets, vide Postscript, 

 p. 30.

in Table. 



Herr Meves records these two species, but not from personal 

 observation, and probably quoting Goebel. Herr Goebel in- 

 cludes P. cceruleus from his own observation ; but his record 

 of P. ater appears to be founded on the single example in the 

 museum. I prefer here to give the latter a doubtful claim to 

 having occurred north of 64° 30' N. lat.
