Pitta atricapilla mngliirana is the name applied to a specimen from San- 
ghir, resembling P. melanocephala from Borneo, and only to be distinguished 
from it by the deeper and less-bright green coloms, as well as the metallic 
tints of the wing-coverts and the deeper and less-silvery blue-green under 
tail-coverts. II. Schlegel, T. D. 1865, p. 190.

Thnmnophilus nigricristatus is described as a new species from the Isthmus 
of Panama, difTering from 2\ iloUatin and P. nffinh in liaving no white in 
the crest. G. N. Lawrence, Proc. Acad. Philad. 1865, pp. 107, 108. {Cf. 
Ibis, 1866, pp. 119, 120, where it is suggested that the supposed new bird 
is identical with T. radiatus.') 
Thamnophilns Jiollandi is described as a new species from Grey town, Ni- 
caragua, allied to T. melanuruSj T. transamlcanus, and T. melanocrissus, but 
is larger, and has a more powerful bill than any of them. It also differs 
from the first two by its blade crissum, and from the last by the black on 
the side of the head terminating in a line with the rictus. G. N. Lawrence, 
Ann. Lyc. N. Y. 1865, pp. 181, 182.

Turin Museum, and corresponds perfectly with the original description. It 
is from Bahia. T. Salvadori, Atti Soc. Ital. Sc. Nat. 4 Sept. 1864.
