from those of A. obscurus, but there appear to be some types which 
do not occur among the eggs of that species. Examples from 
Uruguay are greyish-white, speckled with pale yellowish-brown 
and lavender; while those from the Argentine Republic are cream- 
colour, speckled and blotched with brown and lavender, quite 
half of the ground-colour remaining visible. Specimens measure 
from *76 to ‘95 in length, and from ‘58 to ‘69 in breadth.

The eggs of the Petchora Pipit are of a narrow pointed oval 
shape and but very slightly glossy. The clutches in the Collection 
vary considerably. The eggs of two clutches are cream-colour, 
profusely mottled with brown, to such an extent that in some 
specimens hardly any portion of the ground-colour is visible. The 
markings form a confluent cap at the broad end. The eggs. of a 
third clutch are pale greyish- or purplish-white, very evenly 
blotched all over with purplish-brown and lavender. Specimens 
measure from °8 to *9 in length, and from °57 to °6 in breadth.
