ENTER ODU CETEON: XV

T. MASSENA.

Costa-Rica specimens of this species are said by Messrs. Cabanis and Heine to be
smaller than Mexican ones, and to show signs of a white breast-band. These authors
suggest that, should these differences prove to be constant, the Costa-Rican bird be called
LT. hoffmanni. I have examined a large series from all parts of Central America, and fail

to find any justification for separating the southern bird.

During the progress of the present work, additional information has been published

on the two following species, which I now add :—

TROGON PUELLA.

The range of this species is now known to be much more extensive than formerly
supposed. Its occurrence in Mexico is assured by the receipt of specimens from Senor De Oca,
from the neighbourhood of Jalapa. In Guatemala T. puella is found both in Vera Paz and
in the forests of the great voleanoes of Agua and Fuego, as well as those of the low-lying
lands bordermg the Pacific. From Costa Rica many specimens have been sent, collected
chiefly in the forests stretching towards the Atlantic Ocean. Lastly the most southern point

whence I have seen specimens is the voleano of Chiriqui.

TROGON MELANOCEPHALUS.

Mr. Salvin writes to me, “Of this species the following localities have to be recorded
in addition to those mentioned in your book :—Merida in Yucatan, where Dr. A. Schott
obtained specimens, one of which we possess through the kindness of the Smithsonian
Institution; in Guatemala it is a scarce bird, and we have but one specimen, obtained at
Choctum in the lowlands of Vera Paz; in Honduras T. melanocephalus would appear to
be commoner, as the late Mr. G. M. Whitely obtained many examples of it near Medina
on the Atlantic side; on the Pacific side of the same country I once met with several birds
near La Union in the Bay of Fonseca; Mr. Belt met with it at Chontales ; and I have

seen several examples from Costa Rica, which appears to be the southern limit of its range.”

In general terms, the Trogonide may be said to be distributed at the present day

throughout the forest-countries of the Indo-Malayan Region, Equatorial and South Africa, and
