THE ORDER PASSERES. G'J9

of the most striking instances that can be adduced, to illustrate 

 what is at present termed the direct analogy which the typical 

 groups of families bear to each other. In short, nothing but a 

 complete revision and re-examination of all these birds, will 

 enable us to distribute them in their natural groups ; and even 

 then, where the former descriptions are merely confined to 

 colour, their correct application in very many cases, will be 

 altogether impracticable. The theory of Mr. Vigors, that the 

 Thamnophilinae constitute that aberrant group, which forms the 

 immediate passage to the Thrushes, may appear to be 

 strengthened by the foregoing observations ; nor are we at all 

 surprised that a cursory view of the subject should have led to 

 such a conclusion. 



284. The Drymopliila Velata of Temminck has no affinity with our 

 genus. It belongs to a group peculiar to the Australian range. 



285. Subgenus Cyclaris, Nob. The bill of Tanagria Cfuianensis, the 

 only bird we are as yet acquainted with of this type, is broad 

 and short, not slender. 



387. Lanius Lencocephalus more properly belongs to Vanga. 



290. Genus Psaris. No naturalist of the present day has evinced a more 

 honourable and more scrupulous regard to the names, imposed 

 by his predecessors to generic groups, than has M. Cuvier ; and 

 perhaps there is no one who has been more exposed to the pla- 

 giarisms of inferior writers. We have, elsewhere,* considered 

 it our duty to expose a bold, but, we hope, an unsuccessful at- 

 tempt, to obliterate nearly the entire ornithological nomenclature 

 of the Regne Animal. And, as if the change of Tytira for 

 Psarii was insufficient, we find both these are to give way to 

 Pachyrhynchus. Had M. Spix restricted this name (as we at 

 first conjectured had been done) to the group of which our 

 Psaris Cuvierii forms the type, nothing could have been better ; 

 yet, by applying this new designation to the two groups indis- 

 criminately, it is plain that no intention of indicating their
