* As some explanation of the station I have now assigned to this remark- — 
able type, it must be remembered, that as the Coluwmbide are the most 
aberrant of the rasorial order, so is Chionzs the most aberrant of the Colum- _ 
bide. The experienced ornithologist will discover many beautiful analogies — 
resulting from this arrangement. The above generic characters have been 
drawn up from a careful examination of a specimen in the British Museum. _ 
f As I have every reason to believe, from an attentive study of this family, 
that Crar is an aberrant genus, I have thought it better at once to correct 
my former error, and to name the whole from that group which is one of 
the chief types. | in
