NEOCHLOE.—HYLOPHILUS. 205 
NEOCHLOE. 
Neochloe, Sclater, P. Z. S. 1857, p. 218. (Type N. brevipennis, Scl.) 
Mr. Sclater proposed this genus for the peculiar South-Mexican species which at 
present is its sole occupant. The form of the wings and tail are its chief distinguishing 
characters. The former are very rounded, the second primary being much shorter than 
the secondaries, and the third primary only about equalling them; the tail is about the 
same length as the wings, and also rounded. The bill is slender, but hardly more so 
than in V. huttoni; and the feet and legs resemble those of Vireo. ‘The coloration is 
peculiar, and quite different from that of any other member of the allied genera.

Hab. Mexico, Orizaba (Botteri 12, Sumichrast*), Jalapa (de Oca). 
This seems to be one of the rarest of Mexican birds, as at present we only know of 
three specimens in collections. The type, which was obtained by Setior Matteo Botteri 
near Orizaba on the 8th October 1856, is now in the British Museum ; another is in the 
national collection at Washington, and was also received from the same naturalist. 
The third, which we now figure, is in our own collection, and formed part of a series 
of bird-skins sent to this country some years ago by Don R. Montes de Oca, the well- 
known naturalist of Jalapa. Prof. Sumichrast, who worked so long in the State of 
Vera Cruz, never met with it himself, but includes it in his paper on the birds of that 
State on Botteri’s authority. Nothing whatever is recorded of its habits. 
HYLOPHILUS. 
Hylophilus, Temminck, Pl. Col. sub tab. 173 (1823). Types H. thoracicus and pecilotis. 
Pachysylvia, Bonaparte, Consp. Av. i. p. 809 (1850). Type Sylvicola decurtata, Bp. 
This genus contains about a score of species, all very similar in form, and differing 
from one another by no very marked characters of colour. ‘They are distributed 
throughout Tropical America, from Southern Mexico to Brazil, none, however, being 
found in the West-India Islands, except Trinidad and Tobago. North of the Isthmus 
of Panama four species occur, all of which are found in the State of Panama itself, two 
spreading thence to Southern Mexico. Guiana seems to be the metropolis of the 
genus, where no less than six species have been discovered.
