326 Mr. H. Seebohm on the Ornithology of Siberia. 



midst of a small party of Lapp-Tits. What few birds there 

 are in these vast solitudes are very sociable. I generally 

 found the Lapp-Tits accompanied by a pair of Pine-Grosbeaks, 

 and occasionally by a pair of Nuthatches. The Nuthatch of 

 the Yen-e-say' cannot be separated specifically from the com- 

 mon European form. It is undoubtedly a whiter form. The 

 forehead is whiter, and the flanks are much less rufous. These 

 paler forms are characteristic of Siberia, and have given rise 

 to many new synonyms. Thus the Siberian form of Picus 

 tridactylus has been called P. crissoleucus by Brandt, that of 

 Parus cinctus P. grisescens by Dresser ; and the pale form of 

 Sitta europaea is the S. uralensis of Lichtenstein, the S. 

 asiatica of Gould, and the S. roseilia of Bonaparte. 



Dresser, in his ' Birds of Europe/ describes the legs of S. 

 europcea as ' ' plumbeous grey/' in contradistinction to those 

 of S. c&sia, which he describes as " pale dull brown/' This 

 does not at all agree with my observations in Siberia. The 

 following note was written on the spot, with several fresh- 

 killed birds of each of the two species referred to before me : 

 " The Nuthatch and the Titmouse which are found here are 

 remarkably alike in their general distribution of colour, but 

 differ considerably in the bill and feet. The feet of the Lapp- 

 Titt are lead- colour, almost black. The bill of the Nuthatch 

 is dark lead-colour above, and pale lead-colour below, almost 

 the colour of the back." The feet, on the other hand, seem 

 to have been painted with the same colouring matter as the 

 under tail-coverts, and are pale chestnut-brown, with the soles 

 a dirty yellow. 



CUCULTJS CANORUS, Linn. 



I first heard the Cuckoo on the 5th June, and shot a male 

 a few days later. I did not myself hear this bird further 

 north than 67, but was assured that it was not unfrequent 

 at Doodin'-ka, in lat. 69, nearly at the limit of forest-growth. 



CUCULUS HIMALAYANUS, Vigors. 



On the 15th of June a second species of Cuckoo presented 

 himself, with an entirely different voice to our bird, a gut- 

 tural and hollow -sounding hoo, not unlike the cry of the 

 Hoopoe. This cry can be heard at a great distance, and is
