deep, ratlier reddish brown, the spots being both supcrficiul

 require somewhat careful description.

These eggs may roughly be divided into two types, which 

 I call the '* Blue ■" and " Brown ^' types. 



Shape ovate ; texture smooth and surface glossy. 



Clutch 1. These are the " Brown "" type, and are rather 

 like the eggs of Tardus viscivcrus (Mistletoe Thrush). The 

 ground-colour is a dirty white, the shell thickly covered with 

 superficial and sub-surface splashes of dirty rufous-brown. 



Sizes. 30-0 X 21-5 ; 28-3 X 22-0 mm. 



(Jlutch 2. These are the "Blue" type, quite unlike clutch 1. 

 Resemble rather the eggs of Turdus musicus (Song Thrush). 

 Ground-colour a pale greenish-blue, the shell spotted more or 

 less evenly with small spots, both superficial and sub-surface, 

 of medium brown with a slightly reddish tinge. In one of 

 these three eggs there is no marking at all except one laroe 

 brown splash on one side. This is, of course, a freak.
