A COLLECTION OF BIRD-SKINS FROM SIAM. 205 
scattered over their whole surface. In most eggs the blotches are 
very large, in a few cases four or five covering half the surface of the - 
eggs. Rarely the markings are smaller and more scanty, and are 
sometimes confined almost entirely to the larger end. Scrolls and 
wavy lines, such are so common in eggs of Jerdon’s Wren-Warbler 
(Prinia i. jerdoni) and, to a less extent, in those of the Common Wren- 
Warbler, are very seldom present in these eggs. 
In shape they are broad obtuse ovals, with a very glossy com- 
pact surface, and the texture, though fine, is very stout for such small 
eggs. 
30 eggs average 15.6 x 11.6 mm. The longest, which is also 
the broadest, measures 17.3 x 12.2 mm.; the shortest is 14.9 x 11.3 
mm., and the most narrow 15.4 x 11.0 mm. 
They lay principaily in May, June and July, but many will be 
found breeding as late as August and September, and others again as 
early as April.
