Mr. H. C. Stuart Baxer exhibited some eggs of Indian 
Corvidee and Dicruridz, and made the following remarks :— 
I exhibit some eggs to-night, many of which are very 
common and a few of which are of the greatest rarity, but 
all are selected with the idea of showing the value of cology 
as a scientific asset. The first three boxes shown contain 
three geographical races of one of our most common Indian 
birds, Corvus coronoides, which ranges from Australia to 
Western Asia in one long chain of links. When sorting out 
the eggs in my collection into geographical groups I at once 
found they strongly supported my theories as to the divisions 
of the birds themselves. Thus in Assam, Burma, Siam, and 
the Andamans, we have a large, long-winged, heavy-billed 
bird, laying very dark broad eggs; this form, first named 
from Port Blair, is knownas C.c. andamanensis. C.c. inter- 
medius, ranging from the Western Himalayas to Bhutan, 
lays a longer, much brighter-coloured egg, which is also 
rather smaller. C. c. levaillanti, a smaller race found over 
the greater part of Northern India, lays not only a much 
smaller but a much less richly coloured egg, and, finally, 
when we get to the ever-humid, ever-hot countries of 
Southern India and Ceylon, we find the small, very dark 
bird, C. c. culminatus, laying still smaller eggs, which are as 
dark as those of the large Northern bird living in equally 
wet climates. 
The series of Magpies’ eggs are similar, and we have the 
four races of Pica p. pica of Europe, P. p. bactriana of
