seems to have put on the very plumage of Paehyr - 
hynchus Cuvierii ; while Serilophus, in like man- 
ner, appears to have borrowed the pointed quills 
and broad secondaries of the Flumcolince. Thus 
the great dissimilarity between the types of the 
Eurylaimincn, which, under a confined view, ap- 
pears altogether anomalous, may he accounted for 
on the most simple principles ; namely, that besides 
being bound together by some prominent and general 
characters, they arc also intended to teach us what 
are their immediate allies, and the nature of the 
five great divisions of the whole family. 
Lastly, by comparing the two typical divisions of 
the whole family with each other, we shall not only 
have a clearer exposition of each, but we shall see 
at a glance the relations which each circle, in its 
genera, bears to the other.

Todus and Eurylaimus agree in haying the rictus 
but slightly, or not at all, bristled ; while in Musci- 
capa and Cymbii hynchus these bristles are yery 
long. Megalophus and Serilophus are the rasorial 
types of their respective circles, and both are re- 
markable for their beautiful crests. Monacha and 
Psarisomus represent each other through the me- 
dium of the Psariana ; while the tail is conspicu- 
ously developed, although in different ways, both in
