316 PROCEEDINGS OF THE 



Lams cachinnans, Pall. Is met with here and there on the 

 lakes ; a great number have been remarked on one of the islands 

 of Irtiash. Euss., Bolshaja-Musha. 



Larus argentatiis, L. According to Bogdanoff, it is rather 

 common on the Kama {op. cit., p. 153), but I have not seen it 

 once. Lestris pomarinus and L. imrasiticus, according to Nordmann, 

 build in the Gulf of Finland {op. cit., p. 52) ; Larus minutus (see 

 Eversmann, op. cit, p. 574), according to Lilljeborg, is numer- 

 ous near Novaya Ladoga {op. cit., p. 110), but in Finland it was 

 killed only once, near Uleaborg (ISTordmann, p. 52). I have 

 followed it as far as Pavda. Very strange that Bogdanoff has 

 never met with the Larus canus (op. cit., p. 153), as it is very 

 common in Central Russia. Larus cachinnans, according to Evers- 

 mann, is met with on the large lakes of the Kirkiz steppes 

 {op. cit., p. 569). Bogdanoff traced it as far as Samarska Luka 

 {op. cit., p. 153). Lar^is argentatus migrates sometimes as far as 

 the Government of Jaroslav, and according to Meshakoff {op. cit., 

 p. 635), even builds in the Government of Vologda. 



Sterna hirundo, L. Is met with everywhere ; has been also 

 remarked in Pavda, but not common; it is on the lakes. Bashk., 

 Karahash-ak-sardak ; Zirian, Voja-haUa. 



Sterna nigra, L. It does not go far to the north, and it is not 

 met with higher than 57° N. lat. (on the eastern slope). On the 

 lakes it is more numerous than the Larus minutus. Russ., 

 Clierney-rebalow (black-fisherman). 



Sterna minuta, L. Much more seldom than the preceding, and 

 does not build on the lakes in colonies. Bashkire, Koha-cash-ak- 

 sardak. Sterna nigra is very common in the Government of 

 Moscow, and in parts of the Government of Jaroslav. According 

 to Nordmann, it has been only once killed near Abo {op. cit., p. 

 53). Sterna minuta, according to Nordmann, is distributed as far 

 as the White Sea (op. cit., p. 54). It is not certain whether Sterna 

 leucoptera is met with on the Ural lakes of the eastern slope ; it 

 is common on the lakes of the plains in the Governments 

 of Riazan and Tambow, and according to Bogdanoff {op. cit., p. 

 156), it is met with rather seldom in the Kazan Government. 

 Perhaps Fhalocrocorax carho is also met with on the lakes of the 

 eastern slope.
