This we consider the best and the final test by 
which our proposition that Megalophus , — notwith- 
standing its crest, — is a fissirostral type, can he 
tried. The crest of the Prionops plumatus, although 
of a different sort, is more analogous, in its extra- 
ordinary size, to that of Megalophus, than that of 
any other known bird ; and both further coincide in 
having very pale and delicate feet, upon which the 
scales are so thin that they can scarcely be perceived. 
If we continued the comparison by enumerating the 
other two genera in the above circles, we should 
find that Colluricincla is no obscure representation 
of Monacha ; but the remaining genus in the first 
series (the Thamnophilinw ) being unknown, we 
of course are entirely ignorant of the prototype 
of Rhipidura. 
Having thus endeavoured to substantiate our 
views of the primary divisions of the family of 
Flycatchers, we shall now enter upon the details 
of each. 
By commencing with the genus
