An egg of the Lesser Double-collared Sun-bird is of a very 
narrow oval form and devoid of gloss. The ground-colour is olive- 
ercy and it is streaked and mottled with olive-brown, the markings 
forming a small and indistinct zone at the broader end of the egg. 
It measures *65 by 42. 
A second specimen, of a wider oval form, has the same type of 
markings, but the general colour is of a warm brown, and there 
are a few small spots of darker brown scattered over the shell. It 
measures *65 by *47.

Fees of the Acik Scarlet-chested Sun-bird vary in shape from a 
regular oval to a pointed oval and are very slightly glossed. The 
five odd eggs in the Collection represent two distinct types of 
coloration. In the first the ground-colour varies from pinkish- 
white to greenish-white, and the markings, which are scattered all 
over the shell, are pale violet-grey and dark brown; some of the 
latter markings take the form of spots with blurred edges merging 
into the ground-colour, while others form short irregular lines and 
scrolls. In the second type the ground-colour is greenish-white, 
and the whole surface of the shell is finely and thickly mottled 
with dull olive-brown, or longitudinally smeared with cloudy 
streaks of the same colour. They measure from ‘66 to ‘79 in 
length, and from °48 to ‘53 in breadth.
