The first specimens of the snow-tailed trogon were sent from the area opened up by the Panama Railway, by the trackmaster James McLeannan to the American ornithologist, George Newbold Lawrence (1806-1895). The birds remained with Lawrence for some time and it was not until 1870 that they were named and described by the English zoologist, Dr. P.L. Sclater and Osbert Salvin.
The male's tail is black-tipped purple with distinctive outer feathers of pure white. The female lacks the male's glossy sheen and is dark grey with white outer tail-feathers barred with black. Both sexes have orange-yellow underparts.
In the watercolour two males and a female are depicted. The finished plate portrays only two birds, the female and a male seen from the back. A faint brown pastel sketch of a fourth trogon's head, probably by Gould, is in the top left side of Hart's watercolour.
DISTRIBUTION: Southern Central and western South America. The birds depicted belong to the subspecies Trogon viridis chionurus which occurs in eastern Panama, western Columbia and western Equador
