splendid of the whole race ; and, we doubt not, 
but that many will think so. The exquisite lilac 
reflections on the under plumage defy the painter’s 
art, while the rich cinnamon of the hack admirably » 
contrasts with the full dark blue of the wings. 
We are seldom disposed to pass over a generic 
name which has an undoubted right to priority, 
provided it has no radical defect in its construction, 
but no rule can be absolutely without exceptions ; 
and, in the present instance, Euryttomw is so very 
expressive of one of the chief characters of this 
group, that we are induced to give it the preference 
over Colaris, the Greek name, as it has been al- 
leged, of some unknown bird ; which, of course, 
is as applicable to any other as to this group. 
It is one of the great defects of the Syxtema Avium, 
in many respects a valuable work, that its author is 
continually uniting two or three species of the older 
ornithologists under one specific name, not after 
examination, but obviously, and often confessedly, 
upon mere conjecture, without, in short, having 
seen them. In the present instance, we find the 
E. purpurascms and the rulescens of Vieillot set 
down as the same species ; when, on perusing the 
original accounts of each, no two can 'well be more 
different. 
The size of this species, which seems not uncom-

The bill is of a fine orange-yellow : the whole of 
the upper plumage, including the shoulder and 
lesser wing-covers, the scanulars, and part of the
