Yellow-billed Bean-Goose 103 



effect was given me by Notozero Laps, and by the forester Kormilov at Povenets, on the 

 northern extremity of Lake Onega, who in 1879 had a yearling female hatched from the 

 egg by a hen. This goose, which was remarkably tame, associated with a common drake ; 

 and on seeing the latter would at once run after and follow him about like a dog through the 

 yard, and in the street. 



" I saw two equally tame geese brought in the summer by Mr. N. A. Smirnov from 

 Novaia Zemlia, and living on an enclosed grass-plot near the station on Catherine Island. 1 



" M. arvensis is very easily tamed, and might become perfectly domesticated and 

 replace Anser anser domesticus in the North, especially as the latter breeds badly there." 



In regard to the eggs, I give a table of measurements and weights drawn up by 

 Mr. Gobel, based on 24 specimens from Lapland (Lake Cholme and River Paza). 



Max. breadth 59 mm. ( = 2.32 in.), with 84 mm. (= 3.30 in.) length, and 1320 cgrm. weight. 



Min. „ 54 „ ( = 2.12 „), „ 75 „ ( = 2.97 „) „ „ 1092 



Max. length 87 „ ( = 3.42,,), „ 55.5 „ ( = 2.1 8 „) breadth, „ 1296 „ 



Min. „ 74 „ ( = 2.91 „), „ 54 „ ( = 2.12 „) „ „ 1092 



Max. weight 1338 cgrm., with 58 mm. ( = 2.28 in.) breadth, and 84 mm. (= 3.30 in.) length. 



Min. „ 1074 „ „ 56 „ ( = 2.20,,) „ „ 78 „ ( = 3-07 „) „ 



24 eggs : mean breadth 56.2 mm. ( = 2.21 in.) ; max. breadth 59 mm. (=2.32 in.) ; min. breadth 54 mm. ( = 2.12 in.). 

 24 „ „ length 81.9 „ ( = 3- 22 »); » length 87 „ ( = 3.42,,); „ length 74.5 „ ( = 2.93 „ ). 



21 „ „ weight 1254 cgrm.; „ weight 1338 cgrm.; „ weight 1074 cgrm. 



As regards the colouring and structure of the shell, reference may be made to the notes 

 on eggs in the Appendix. 



1 The geese brought by Smirnov, here spoken of by Mr. Gobel, according to the skin of one of them, now in the Zoological Museum 

 of the Imperial Academy of Science at St. Petersburg, belonged to M. segetiim.
