 Dresser, Man. Palsearct. B. p. 593. 



Two esrffs taken at Bham-tso on the 9th of June. 1905. 

 They resemble those of the European Grey Goose in shape 

 and coloration, and measure 3*26 by 2*16 inches. Unfortu- 

 nately no down was sent. 



Perdix hodgsoni.e Hodgson. Tibetan Partridge. 

 Dresser, Man. Palsearct. B. p. 084. 



One clutch of five eggs with the parent bird, obtained near 

 Gyantse on the 17th of June, 1905. These eggs resemble 

 some of those of Perdix cinerea in my collection in being 

 brownish cream-coloured, and measure from 1*40 by 1*05 to 

 1-45 by 1'07 inch. 



(This Partridge breeds in the grass between the fields. I 

 found one nest containing five, and another containing 

 four eggs.) 



Tetraogallus tibetanus Gould. Tibetan Snow-Partridge. 

 Dresser, Man. Palsearct. B. p. 690. 



One clutch of six eggs with the hen bird, obtained near 

 Gyantse on the 2nd of June, 1905. In general appearance 

 these eggs resemble those of Tetraogallus caucasicus, being 

 clay-buff tinged with oil-green, and well spotted with dull 

 dark rufous, but some of them are rather paler with little 

 tinge of oil-green. They are smaller than those of any other 

 species of Tetraogallus, measuring from 2 # 29 by 158 to 2*31 

 by 1*63 inches. 



(The nest was composed of grass and feathers, and was 

 placed under the shelter of a rock at the top of a high rocky 

 mountain at an altitude of 15,000 feet. The call of this 

 bird is Partridge-like, and it is a great runner, appearing 

 only to fly when suddenly frightened. In the winter it 

 unites in coveys of from twelve to fifteen individuals.) 



The egg of this bird was well figured in the Cat. of Birds' 

 Eggs in Brit. Mus. vol. i. pi. ii. fig. 7, but the specimen there 

 figured is much paler than those above described and has. 

 none of the oil-green tinge.
