The eggs of the Malayan Yellow-breasted Sun-bird are extremely 
variable. They range from a narrow to a broad oval form and are 
without gloss. In some specimens the ground-colour is nearly 
pure white, in others greyish-white, pale greenish-grey, or brownish- 
white. Some eggs are densely mottled all over with brown and 
underlying lavender; others are blotched and clouded with pale 
purplish-brown and lilac-grey ; others again are marked with well- 
defined spots and blotches of purplish-grey and dark brown. Many 
specimens exhibit a large cap of confluent markings at the broad 
end, others are evenly marked all over. Many eggs, like those of 
C. flammavillaris, are sparingly spotted with dark purplish- or 
chocolate-brown. Specimens measure from ‘67 to *7 in length, and 
from *41 to -48 in breadth.
