of the continent into Venezuela (and some of the islands 
lying contiguous to it)^ Guiana^ and Brazil as far south as 
Rio Janeiro. To review rapidly the distribution of the species 
acknowledged as such in this paper_, and commencing at the 
most northern limit, we find that T. candidus is an inha¬ 
bitant of Southern Mexico, and ranges through Guatemala 
into Honduras, which country appears to be its southern boun¬ 
dary. In British Honduras also T. lucice has been procured. 
In Costa Rica the beautiful T. chionurus is found, and is evi¬ 
dently very common in Veragua and Chiriqui. Proceeding 
southward we come to Columbia, which possesses more spe¬ 
cies of this genus than any other country. T. milleri is com¬ 
mon in the vicinity of Bogota, and is said to extend its range 
into the interior towards the head-waters of the Rio Negro. 
From Bogota has also been received the unique specimen 
called by Mr. Gould T. cceriileiceps, and also the rare species 
T. apicalis of the same author. T, tobaci has been ob¬ 
tained here, and also T, leucogaster, described as terpna, if 
I am correct in referring Dr. Cabanis^s bird to that species. 
Continuing south we find that Ecuador possesses but one 
representative of this genus, T. viridiceps, closely resem¬ 
bling T. milleri, and difiering principally in its larger size. 
Peru contains two species—the T. fluviatilis, dwelling on the 
Rio Napo, the Upper Ucayali, and also in the vicinity of 
Pebas, and the rare T. bartletti, discovered on the Upper 
Ucayali by the collector whose name it bears. Bolivia, the 
most southern of the countries on this side in which any 
species of Thaumatias is found, is the home of T. neglectus, 
brought by D^Orbigny from Yungas and Moxos. Return¬ 
ing now to the northern part of the continent, and com¬ 
mencing with Venezuela, we find that T. chionopectus has been 
procured near Merida (whence it was sent by Mr. Goering), 
this species also ranging into Guiana and the island of Trini¬ 
dad. T. tobaci is also a native of Venezuela, and has been 
procured in the islands of Tobago and Trinidad. It con¬ 
tinues its range through Guiana as far south as Para; and 
as it has also been obtained in Columbia, the probability is 
that it is an inhabitant of the valley of the Amazons throughout
