THE BIRDS OF AUSTRALIA. 
Ring-Plovers, a quite different type of egg is observed which seems to reappear 
in Africa, Austraha and New Zealand, and is seen in the eggs of L. {Helencegialus) 
pecuarius and sanctcehelence, ’i Afroxyechus tricollaris, Elseya mdanops^ and 
TTiinornis novce-zelandice. Whether these are interrelated is a problem yet 
to be solved : superficially they do not seem to be, while they all obviously 
differ from Charadrius. In any case, the need of careful study of eggs cannot 
fail to be impressed upon anyone who examines a series of them in conjunction 
with critical comparison of birds. The constant recurrence of the typical 
form of egg seems to have prejudiced most systematists who have casually 
glanced at long series of the eggs of birds in a large genus, and hence their 
recent neglect.
