Mr. Edward Bartlett in Eastern Peru, at Nauta, on the Upper Ucayali, as well as a Yurimaguas, Xeberos,
and Santa Cruz, while Mr. Henry Whitely has shot it in the valley of the Cosnipata in Peru.

The British Museum possesses a specimen from Para, procured by Mr. R. Graham, and Mr. Wallace met
with it in the same locality. In his excellent work on Natterer’s Ornithological Travels in Brazil, Herr von
Pelzeln enumerates | places where that model collector obtained specimens. Like the naturalists
above mentioned, Natterer found it at Para, and higher up the country on the Rio Negro, at Barra, and
Maribitanas ; he also procured it in Central Brazil, in the province of Matto Grosso, at Villa Maria, and
on the Rio do Sipotuba.

As is the case with nearly all the Trogons, the details as to the habits of the present bird are very scanty.
Mr. Fraser alone gives a short note on the species procured by him at Babahoyo, as follows :—* Native
name Chocota. Irides white; upper mandible with a large yellow spot at the base, lower mandible yellow ;
legs and feet greenish, soles yellow. Much more active than any other Trogon which I have yet had an
opportunity of observing, hopping from branch to branch in the lower part of a large tree in the deep bush,
solitary and silent.”

On this species Mr. Salvin writes to me :—

“Many authors consider that this bird should bear Linnzeus’s name Trogon curucui; but it is evident,
from the references added to the diagnosis given in the ‘ Systema Nature,’ that more than one species was
confused under the name cwrucui. Moreover Dr. Cabanis, whose authority on such subjects is entitled to
the highest respect, considers that the name curucw belongs not to the present bird but to 7° collaris, a
view, again, disputed by Dr. Finsch. Under these conflicting opinions I believe that the interests of science
are best served by considering Linnzus’s name to be incapable of accurate determination, and by selecting
the first subsequently proposed name, about which no reasonable doubts can be entertained. The name
melanurus, bestowed by Swainson, thus becomes a proper title for this Trogon; and as one of Swainson’s
types is still preserved in the Museum of the University of Cambridge, this name may be used with the
greatest confidence. The specimen is a female and bears on its label ‘* Trogon nigricauda, Sw.  Black-
tailed T. Cayenne,”—from which it would appear that although Swainson first thought of using for this bird
the Latin rendering of * black-tailed,” he adopted the Greek translation when describing it. Under the
former it appears in the first edition of the Trogonide.

“The bird from Western Ecuador has been separated by Messrs. Cabanis and Heine as Zroctes mesurus,
the differences being stated to consist in its slightly larger size and slight modifications in the coloration
of the lower back and the tail-feathers and in the mottling of the wing-coverts. As these differences are
traced from the comparison of only four specimens of the two species, it may well turn out that they are
not sufficiently pronounced to lead to the conclusion that two really distinct birds of this form exist.”
