near Ekaterinburg; in 1867 some were seen near Tagila; and in 

 1868, I think, near Ekaterinburg. 



Podiceps auritus, Briss. Is very numerous on the lakes of the 

 south-eastern slope. Kuss., Gagara; Bashk., SejjJcai, 



Podkeps cormitus, Lath. More common, and sometimes builds 

 in whole colonies. It is not distinguished from the preceding 

 species. Hoffmann found it near Berezoff (op. cit, p. 70). 



Podkeps cristatus, L. Is very numerous, and breeds by 

 hundreds, so that the nests are very near one to the other. 

 Bashk., Urlan; Zirian, Gerd-dura-gogara. 



Podkeps subciistatus, Tacq. Has not been remarked by me, 

 but Middendorff followed its migration near Ekaterinburg (see 

 Isepiptesen, p. 79). Probably it is also met with on the lakes of 

 the Black-earth plain. According to Nordmann, it also builds in 

 Finland {op. cit, p. 49). 



Col'ijmhus ardicus, L. Is distributed all over the Government 

 of Perm, but is especially numerous on the lakes. Euss., 

 Bolshaja, Setzevaja gagara; Bashk., Mesch., Kukey. 



Cohjmbiis septenirionalis, L. Is more seldom met with, but it 

 seems its distribution is about the same as that of the preceding 

 species. Russ., Bolshaja Setzevaja gagara, sometimes Krasnozohaja. 

 Bogdanoff doubts that both Cohjmhi, as Eversmann says, build 

 in the Government of Kazan. However, they build in the 

 Governments of Jaroslav, Vladimir and Twer (Bogdanoff, op. 

 cit, p. 158). They also build in Finland (Nordmann, op), cit., 

 p. 50). 



Lestris pomarimis, Temm. (1) It is uncertain whether it is this or 

 another species of Skua. According to sportsmen, sometimes nests 

 on the lakes of the Kaslinsky Ural ; and in the spring and autumn 

 it is met with very often there. Russ., Chernaja-Musha. 



Lams minutiis, Pall. Contrary to Eversmann's opinion, it breeds 

 on the lakes in great colonies, and it is more numerous than any 

 other species of gull. Russ., Maley-rebalow ; Bashk., Mesch., 

 Ak-sardack. 



Larus ridihundus, L. Is met with everywhere, and is also very 

 common, especially on the lakes Charka. Zirian, Lez-kalia. 



Larus canus, L. More seldom than the preceding species ; 

 builds in the bogs (marshes), also in colonies. Russ., Klusha, 

 Baklusha (Teplouhoff ); Bashk., Mesch., Ak-bash, Ak-sardack (mean- 

 ing white, white-headed) ; Zirian, Teycljid-kalia.
