The eggs of Eversmann's Eedstart are of the same type as those 

 of P. auroreus. They are pale blue, delicately mottled and speckled 

 with pale rufous, the markings forming an ill-defined zone round 

 the broad end. Two examples measure respectively : -76 by -57 ; 

 •7 by -54.

The eggs of the Blue-fronted Redstart are either of two very 

 distinct types, or they have in some cases been wrongly identified 

 by the naturalists who collected them. 



Three eggs sent to Mr. Hume from Sikhim, and now in the 

 Collection, are avowedly of somewhat doubtful identity ; they 

 are of a pale delicate blue colour and of a pointed oval shape, 

 moderately glossy, measuring respectively : '87 by -58 ; "81 by -6 ; 

 ■85 by -6. 



Eggs received by Herr Nehrkorn, also from Sikhim and said to 

 belong to this species, are described by him as being uniform pale 

 blue. The measurement of these eggs is given as 21 x 25 mm., 

 apparently a misprint. 



Mr. Hartert, describing a number of eggs of this Eedstart from 

 Koko-nor, collected by Herr Tancre's men, states that they are of 

 a delicate greenish blue, with more or less indistinct small rufous- 

 brown spots near the larger end, in some almost invisible, in a 

 few others forming a very distinct and obvious ring. Four of 

 these specimens, acquired in the Crowley Bequest, are now in the 

 Museum. They are much darker than the eggs in the Hume 

 Collection, excessively glossy and measuring respectively r -89 by -6 ; 

 ■84 by -6 ; ■SI by -61 ; ■85 by -6.
