The third form which inhabits the country is C. baical- 

 ensis, Dresser. In the Sayan range it is almost as common 

 as C. bianchii, but is distributed very much more widely, the 

 extreme points of its area being Baical, Krasnoyarsk, Russian 

 Altai, and N.W. Mongolia. 



Phylloscopus tristis axillaris, n. subsp. 

 A Ph. tristis subalaribus et axillaribus isabellino-albidis stra- 

 guloque magis grisescenti distinguenda. 

 Hab. Ad cursum medium rluminis Yenisei (55° N. lat.). 



Regulus cristatus coatsi, n. subsp. 

 JR. cristato simillimus, sed pilei lateribus et nucha cinereis, 

 vix lutescenti lavatis, nee obscuris, ut in R. japonico. 

 Hab. Jugi Sayan zona subalpina. 



Pgecile cincta sayana, n. subsp. 

 Ad P. cinctam typicam maxime accedit ; rostro multo 

 longiore et crassiore ; subalaribus et axillaribus conco- 

 loribus, ferrugineo-bruunescenti tinctis, rectricibus 

 indistincte cinereo nee flavescenti-griseo limbatis, pileo 

 magis cinerascenti, ut in P. obtecta. Ala 73 mm., 

 cauda 69, culmen corneum 11, a glabella 13, rostrum a 

 narina 95, gonys 8. 

 Hab. Sayan occidentalis, Altai. 



Obs. It is rather remarkable that this new form is decidedly 

 more like the western P. cincta, Bodd., and not the 

 Siberian P. cincta obtecta, Cab. This case is parallelled by 

 the fact that the Spotted Woodpeckers of Sayan Range 

 (Picus major, leuconotus, minor, Apternus tridactylus) 

 belong to the typical European forms, whereas at Kras- 

 noyarsk they are replaced by pale Siberian subspecies. 



The Remiz Titmouse proved to be very common at the 

 upper course of Yenisei, south of Sayan. I only got 

 specimens in autumn plumage ; but though there were 

 adult birds among them, none of those obtained or 

 observed had any trace of the typical black " moustache." 

 Hence this bird should be considered as new, and may be 

 provisionally described as : — 



Remiza yeniseensis, n. sp.
