always along the rocky shores of the rivers. In Pavda, 

 Smettannick, Kamennaja utka (stone duck), Skreben; near Ekater- 

 enburg, Malenhj-cherock. 



Rhynchaspis clypeata, L. Is very common on the lakes to the 

 north from 50° N. lat.; it is rather rare, but I think it is met 

 with in Pavdinsky Dacha (Tagila also). Euss., SheroJconoska, 

 Saddun, Sochun-hogater. In the district of Perm, Plutonos (Tep- 

 louhoff) ; Bashk., Hog-hog (by the voice). 



Oidemla fusca, L. It is very numerous on the lakes, and builds 

 in small numbers throughout the Government of Perm. Euss., 

 TiirjKm chernimshka chermiha; Bashk,, Kara-urdeck. 



Oidemia nigra, L. Is met with on the lakes during migration 

 only, and it is also seen in the summer. Probably builds on the 

 Ural and north part of the Perm Government. Euss., Maletj- 

 turpan-chernimshka ; Bashk., Suktabasli. Eversmann has never 

 traced it even during migration {op. ciL, p. 540). According to 

 Nordraann, it builds in Lapland (oj). clL, p. 46); according to 

 sportsmen in Kaslinsky, 0. p)erspiciUata (?) is sometimes seen and 

 breeds there. 



Und'ina mersa, Pall. Breeds on the lakes of the Shadrinsk dis- 

 trict (lake Uvelky), and sometimes on the lakes of the Kasha Ural. 

 Bashk., Aumhach (?). According to Eversmann, it is met with in 

 the northern parts of the Orenburg Government (oj). cit., p. 542), 

 which was also remarked by Pallas (Voyages, vol. iii., p. 61) in 

 the district of Cheliabiansk. 



Glaucion dangida, L. Breeds throughout the Government of 

 Perm, especially on the northern half; on the steppe lakes only 

 during migration. Euss., Gogol; Bashk., Alasahar. 



Harelda gladalis, L. Is very common in the Ural, and 

 probably breeds on the lakes of the Shadrinsk district ; during 

 migration it is very numerous there. In the district of Ekaterin- 

 burg, Kaveka (by the voice), and sometimes Lilneek; in Pavda, 

 Savka; Bashk., Shaitan-cash. 



Harelda histrionica, (L.) Is met with more seldom than the 

 first species, but according to the Bashkires it builds in 

 the district of Shadrinsk. Of course, H gladalis also breeds 

 in the Government of Orenburg, as was remarked by Eversmann 

 (op. dt, p. 545), which Bogdanoff doubts (op. dt, p. 150). According 

 to our observation, it breeds in the Government of Jaroslav 

 (Danilov district); according to Nordmann it also nests in
