altogether different from that species, having the head and 
crest earthy-brown instead of white, and the back of a much 
darker grey. 
We have therefore :— 
P. 1. leucocephalus (Gigl. & Salvad.), Cochin China and 
Siam. 
P. 1. annamensis, subsp. nov., Annam. 
- P.1. incognita (Hume), Tenasserim. 
P. 1. cambodianus Sharpe, Cambodia. 
My. P. F. Bunyarp exhibited an unusually small egg of 
the Cuckoo found in a nest of the Hedge-Sparrow in 
Worcestershire. It measured only 20 x 15 mm., the average 
measurements for 625 eggs being 22°41 x 16°52 mm. (Rey). 
It was, however, heavy for its size, weighing 0°198 mg., the 
average weight for 710 eggs being 231‘1 mg. (Rey). Mr. 
Bunyard said that his experience showed that Cuckoos’ eggs 
were generally larger than those of the foster-parents, 
whereas the egg shown was considerably smaller, and the 
smallest he had seen. He did not claim that this egg was 
a record, but would be interested to know if a smaller 
British egg was in existence. 
Mr. H. Munrt exhibited two eggs of the Mikado Pheasant 
(Calophasis mikado), laid in captivity. |
