It is possible that some of the eggs enumerated below may 

 appertain to the closely allied race or species, C. mandti, but 

 there is no evidence to determine this. 



The eggs of the Black Guillemot are quite different from those 

 of Uria troile. They are of a regular broad oval form, slightly 

 rough, and they possess a small amount of gloss. The ground- 

 colour varies from a creamy white to pale blue pink or pinkish 

 buff. The markings, which consist of spots and blotches, are 

 pretty evenly distributed over the shell and are of a deep brown, 

 black, yellowish brown or chocolate colour. In addition, there are 

 underlying pale purple markings. Not unfrequently the markings 

 form a confluent broad zone round the larger end. Specimens 

 measure from 2-1 to 2-55 in length, and from 1-4 to 1*7 in breadth.
