Mr. D. G. Elliot on certain Species of 
III.— Remarks on certain Species of the Corvidae and Paradi- 
seidse^ with a Description of an apparently new Species of 
Cyanocorax. By D. G. Elliot_, E.R.S.E. &c. 
In the lately published third volume of his ‘'Catalogue of Birds^ 
(p. 317 et seqq.), Mr. Sharpe has acknowledged three species 
of the genus Platylophus, as follows :—P. galericulatus (Cuv.), 
from Java, with a jet-black plumage; P. ardesiacus, Cab., 
from the Malayan peninsula, with a slaty black plumage (back 
inclining to olive-brown, beneath slaty grey); and P. coronatus 
(Raffles), from Sumatra and Borneo, with a rufous-brown 
plumage. Cuvier (who evidently named the bird from Le- 
vaillant’s figure) and Vieillot (who gave a short descrip¬ 
tion of it in the same year, under Cuvier’s name) apparently 
had never seen the species, and their type specimens, if ex¬ 
isting, are not known. Having had occasion lately to inves¬ 
tigate a portion of the Corvidse, my attention was drawn to 
the specimens in the Paris Museum which served as the 
types of Lesson’s Vanga galericulataj which he refers to 
Cuvier’s Garrulus galericulatus, and the result of my exami¬ 
nation is as follows :—There are two examples, representing 
male and female, both brought from Java by M. Diard in 
1821. The male is in the black dress characteristic of 
P. galericulatus, Cuv., but is not in fully adult plumage, as I 
perceive by comparison with another male, also from Java, 
brought to the museum in 1861 by M. Steenstra. Lesson’s 
bird has the greater coverts, primaries, and secondaries greyish 
brown on the outer webs, while this part in the adult is dark 
purplish brown. The back is also inclined to a greyish hue. 
In other respects it resembles M. Steenstra’s adult specimen, 
though not quite so black in any part of its plumage. 
The female of Lesson’s example (so marked by its collector) 
has the wings and body rufous and the tail slaty black, and is 
in the style called Lanius coronatus by Raffles. Two young 
males in the museum from Malacca are intermediate between 
these type specimens, having rufous wings, a greyish back, and 
slate-grey beneath, and many of the feathers tipped with white. 
This is the style termed P. ardesiacus by Cabanis ; but the ex-
