oval shape, and usually exhibit a fair amount of gloss. Tho 
ground-colour varies from a clear greenish-blue to a dingy olive- 
green, marked with different shades of brown, varying from pale 
erecnish-brown to blackish-brown or even black, and underlying 
lavender. The markings on many specimens are small, distinct 
and sparse, on others blotchy or cloudy and frequently confluent 
on the larger half of the egg, where they form a very irregular cap. 
Between these two extreme types, variations of every kind may be 
found in a large series. Examples measure from 1°66 to 2-1 in 
length, and from 1:2 to 1:42 in breadth.
