N.B.—I do not know Garrulus albifrons, figured by J. Gray on 
plate 12 of the second volume of Hardwicke, Ind. Zool. Ill., but not¬ 
withstanding the authority of Hartlaub, judging as he does from the 
figure, I have no hesitation in declaring it is not a Jay. 
The fourth genus of my Garruline subfamily is Cyanogarridus, Bp., 
a North American group, dismembered from Cyanocorax , Boie, for 
the distinction of the Blue true Jays with shorter bills, short-tailed 
and crested, much more allied to the European Garruli than to the 
South American Cyanocoraces. Three species are known : cristatus, 
L., Stelleri, Pall., and coronatus, Sw. 
Not professing Mr. Strickland’s principles as to the appropriation 
of names, we borrow from him the classical one Cyanocitta for a fifth 
group, still composed of a dozen species of both Americas, such as 
fiavidanus, ultramarinus, &c., of which genus we shall say no more 
on this occasion, in hopes that such elegant birds tinged with blue 
will shortly make their appearance in a peculiar monograph published 
in the same style and with the same joint authorship as the mono¬ 
graph of those birds tinged with red , the Loxiince , just ready to appear 
by the exertions of Dr. Schlegel and myself. 
A sixth genus will necessarily be the one to which I restrict Boie’s 
name of Cyanocorax , because even by their size and less brilliant 
colours they are really Blue Crows, such as C. azureus and violaceus, 
which latter, even by its nuchal ornament (beautiful ornamental spot), 
shows a passage on one side to C. ornatus, (which with the other 
smaller elegant species, such as armillatus, have again a tendency to 
the Jays;) and on the other, by C. cay anus, to the white-tailed spe¬ 
cies, much more crow-like, and which five, as they are, might consti¬ 
tute the group TJroleuca. 
Then comes seventh, with its yellow tail, my new genus Xanthura, 
composed of three South American birds formed and coloured as 
Corvus peruvianus, one of which exhibits also the elegant nuchal spot 
which so much contributes to show the South American birds con¬ 
nected. The last of Cyanocorax must be the Sanblasiana, so ab¬ 
normal as to deserve perhaps the generic appellation of Cissilopha. 
More than ever convinced of the propriety of using old names for 
modified groups, I persist of course in retaining that of Cyanurus, 
Swainsonian synonym of Cyanocorax, but recalling attention to the 
tail, for the long-tailed Blue Jays with black bills : of these, two 
undescribed species appear to live in the far east of Asia, quite as 
beautiful as the two celebrated ones of occidental America, upon which 
so many names have been lavished:
