oval shape, and usually exhibit a fair amount of gloss. The 

 ground-colour varies from a clear greenish-blue to a dingy olive- 

 green, marked with different shades of brown, varying from pale 

 greenish-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.
