rosalba ” referred to. It is quite possible that the Couroucoui of Marcgrave, as well as the Trogon brasiliensis 
viridis of Brisson, also refer to the same species ; but of this there appears to be less certainty. Trogon 
collarls has a very extensive range in South America. Levaillant’s “ Couroucou rosalba ” is said to have 
come from Cayenne; and in the adjoining country of Venezuela it is also found, as well as in the island of 
1 rinidad, where Leotaud and also Mr. E. C. Taylor met with it. The Venezuela bird has been separated 
under the name Trogon exoptatus by Messrs. Cabanis and Heine; but, judging from a skin obtained by 
M. Goering at Caripe, I more than doubt the validity of this supposed species. 
Mr. Salvin’s notes on the species are as follows :—“ From the States of Columbia skins of Trogon collarls 
are not unfrequently sent in the collections made in the vicinity of Bogota ; and quite recently Mr. T. K. 
Salmon, who is now engaged in exploring the districts in the neighbourhood of Medellin, has sent a number 
of specimens. These differ to a slight extent from normal T. collarls chiefly in having the terminal white 
portion of the tail-feathers narrower. In this respect they stand in an intermediate position between/ 7 , collarls 
and the Central-American T. paella, in which the terminal white tail-band is almost of the same width 
as the rest of the bars of the tail. This bird has also received a name from Messrs. Cabanis and Heine, 
who call it T. vlrginalls, their description being based upon specimens obtained by Fraser at Pallatanga, in 
Ecuador. The difference, so far as I can see, is very slight, and traced from a very variable character in 
this group of the Trogonid®. Passing on to Peru, Mons. Constantine Jelski met with T. collarls during 
his expedition to the district of Junin. The places where he collected specimens are recorded by 
Hr. Taczanowski as Monterico, Soriano, and Amable-Maria. Turning eastwards from this point into the 
valley of the Amazons we find that Mr. Bartlett met with it both on the Upper and Lower Ucayali and also 
at Chamicuros. Spix also obtained it at Tabatinga, and Natterer at Barra do Rio Negro. The latter 
traveller also sent specimens from the ‘ Engenho do Capt. Gama ’ and Villa Maria, in Mato Grosso. Lastly, 
in Eastern Brazil Prince Maximilian found it at Rio de San Mato, near Bahia; and under the name of 
Trogon eytoni it has been recorded by Fraser from Rio de Janeiro. 
“ Little has been noticed of the habits of T. collarls. Spix speaks of its food consisting of fruit and insects; 
and Leotaud gives the following note of its habits as observed by him in the island of Trinidad :—‘ Ce joli 
Couroucou est sedentaire ici. Ses mouvements sont lents et rarement repetes ; il semble ainsi ne renoncer 
qu’a regret a un repos que troubleraient deja trop souvent les besoins de l’existence. Son cri est rond, 
mais peu sonore; il a cependant un timbre qui attire fattention ; on eroit y decouvrir une certaine crainte 
de rompre le silence si solennel de nos forets ; c’est le cri de certains oiseaux de proie nocturnes qui trouble 
a peine le calme de la nuit. Sa parure si brillante ne redouterait point le vif eclat de la lumiere, et 
pourtant l’oiseau ne quitte jamais les endroits couverts et surtout eloignes et eleves. Sa nourriture 
consiste principalment en baies et en insectes.’ ”
