The experienced ornithologist need hardly be re- 
minded, that when two groups are compared whose 
rank and situation are either remote or very dissi- 
milar, the analogical resemblances between them 
trill partake of the same remoteness ; hence it 
sometimes happens, that although they agree suffi- 
ciently strong in some parts to make ns feel suffi- 
ciently confident that the analogies are just, yet 
others will he so obscure that their correctness can 
only he established by a line of inductive reasoning, 
and their mutual relations come to light through 
the instrumentality of other groups. Applying this 
undoubted fact to the foregoing table, we shall find 
some of the analogies more apparent than others ; 
and we are therefore to inquire, how far those 
which seem the most remote can be placed on the 
same degree of probability with the others. There 
can be no doubt, for instance, that the true fly- 
catchers, forming the genus Muscicopa, are the
