The eggs of the Alpine Eing-Ouzel, judging from the small series 

 in the Collection, do not differ from those of T. torquatus. The 

 majority resemble the common type of Blackbird's egg. Specimens 

 measure from 1"14 to 1-34 in length, and from -85 to -91 in 

 breadth.

The type of the eggs of the Grey-headed Chestnut Thrush in the 

 Collection is very similar to that of the previously described Merula 

 houlhoul (cf. p. 95). They are of a pale greenish -white colour, 

 profusely and evenly mottled and speckled all over with pale 

 chestnufc-brown. One of the eggs differs from this type in being 

 much less heavily marked, the dense freckling being replaced by a 

 mottling of rather darker brown, much of the ground-colour being 

 visible. They measure from 1"10 to 1*25 in length, and from 

 •86 to -9 in breadth.
