Bar-headed Goose 139 



The nest is described as a shallow depression in the ground, lined first with 

 the stalks of soft plants and above with down and feathers, so that in this respect it 

 accords with the descriptions of nests of other members of the group. 



The eggs, 4 to 6 in a clutch, are nearly elliptical in shape ; and the shell is somewhat 

 rough, white, and without any gloss. 



Mr. Gobel has drawn up for me the following table of measurements of the eggs of 

 Turkestan specimens of this species : — 



Max. breadth 58.5 mm. ( = 2.30 in.), with 78 mm. length (= 3.07 in.), and 1422 cgrm. weight. 



Min - » 56.5 » (=2.22 „ ), „ 81.5 „ „ (=3-20 „ ), „ 1422 „ 



Max. length 82.5 „ (=3.24,,), „ 58 „ breadth ( = 2.28 „ ), „ 1392 „ 



Min. „ 78 „ ( = 3.07,,), „ 58.5» „ ( = 2.30,,), „ 1422 „ 



Max. weight 1422 cgrm., with 56.5 mm. breadth ( = 2.22 in.), and 81.5 mm. length (=3.20 in.). 



Max. „ 1422 „ „ 58.5 „ „ ( = 2.30,,), „ 78 „ „ ( = 3.07 „). 



Min. „ 1392 „ „ 58 „ „ ( = 2.28,,), „ 82.5 „ „ ( = 3.24,,). 



Or 



Mean breadth 57.5 mm. ( = 2.26 in.); max. breadth 58.5 mm. ( = 2.30 in.); and min. breadth 56.5 mm. ( = 2.22 in.). 

 „ length 80.6 „ (=3.17,,); „ length 82.5 „ ( = 3.24,,); „ „ length 78 „ ( = 3.07,,). 

 „ weight 1380 cgrm.; „ weight 1680 cgrm.; „ „ weight 11 83 cgrm. 



According to other information, the eggs attain a length of 83.8 mm. ( = 3.30 in.), and, 

 probably, we are still far from knowing their extreme variations in these respects.
