Only one species of this genus is now admitted, the common I. pitangua, which 
ranges throughout Tropical America from Southern Mexico to South Brazil. The only 
specimen that at all departs from the normal type is a male from Presidio, near 
Mazatlan ; this has the top of the head grey rather than black. It is the only record 
we have of the existence of the species in Western Mexico, but without a larger series . 
for comparison we do not think it advisable to do more than note the fact of its differ- 
ence. The northern range of I. pitangua does not extend quite so far as that of 
Pitangus derbianus, Tampico being its limit on the eastern side of the cordillera. 
Sumichrast speaks of it as frequenting both the hot and temperate country 4% Our 
specimens from this district were obtained from the slopes of the Cofre de Perote down 
to the port of Vera Cruz. In Guatemala too its vertical range is very considerable, as 
it is to be found as high as 5000 feet in the Volcan de Fuego down to the level of the 
sea. It is one of the commonest birds throughout our region. 
MUSCIVORA. 
Muscivora, Cuvier, Leg. An. Comp. tab. 2 (1800) (type Todus regius, Gm. apud G. R. Gray, List 
Gen. Birds, ed. 2, p. 42 (1842)); Scl. Cat. Birds Brit. Mus. xiv. p. 191. 
In this remarkable genus the development of the crest, characteristic of so many 
species of Tyrannide, is carried to a much greater extent than in any other form, and 
constitutes one of its most marked features. | 
Four species are now recognized as belonging to Muscivora, all of them strictly birds 
of hot tropical forests of the Neotropical Region. The single species of our country is 
found in such situations from Southern Mexico to the State of Panama, and in the 
most northern parts of Colombia. J. occidentalis is the bird of Western Ecuador, 
M. regia that of Guiana and the Amazons valley, and MV. swainsoni that of the forests 
of Eastern Brazil.
