In order to understand why the genus Cymlirhyn- 
chus stands opposite the Eurytaimince , we must 
remember that it is Eurylaimus which is the pre- 
eminent type of its own particular circle ; and that, 
consequently, Cyinbirhynchus becomes the sub- 
typical genus. Platystomus and Querula agree, not 
only in the general cast of their plumage, but 
actually in the structure of their lengthened wings, 
the proportion of their quill -feathers, and in their 
unusually small feet. It is, in short, by the ap- 
proximation of these two forms, that the circle of 
the entire family becomes manifest. Psarisomus is 
an evident representation of the Psariance, and
