EURYLAIMINJZ. 249 



seems to have put on the very plumage of Pachyr- 

 hynchus Cuvierii; while Seriloptius, in like man- 

 ner, appears to have borrowed the pointed quills 

 and broad secondaries of the Fluvicolince. Thus 

 the great dissimilarity between the types of the 

 EurylaimincB) which, under a confined view, ap- 

 pears altogether anomalous, may be accounted for 

 on the most simple principles ; namely, that besides 

 being bound together by some prominent and general 

 characters, they are 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. 



SUB-FAMILY M USCICAPIN/B. SUB-FAMILY EURYLAIM1NJJ. 



Todus. Eurylaimus. 



Megalophus. Serilophus. 



Muscicapa. Cymbirhynchus. 



Monacha. Psansomiis. 



Rhipidura. Platystomus. 



Todus and Eurylaimus agree in having the rictus 

 but slightly, or not at all, bristled ; while in Musci- 

 capa and Cymbirhynchus 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
