In order to understand why the genus Cymbirhyn- 

 chm stands opposite the Eurylaimince^ we must 

 rememher that it is Eurylaimus which is the pre- 

 eminent type of its own particular circle ; and that, 

 consequently, Cymbirhynchus 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 Psarianae^ and
