GLAUCIS. 255 
the feet are small and feeble, the distal portion of the tarsus bare; the tail is rounded, 
the central rectrices not projecting beyond the curve of the rest. 
The range of Glaucis is very extensive, including nearly the whole of tropical 
America from Costa Rica southwards, and it also occurs in the West-Indian island of 
Grenada. According to Reichenbach his Rhamphodon chrysurus is a Mexican species. 
This bird is undescribed, but Mulsant says it is the same as Glaucis dohrni, a Brazilian 
species. ‘The Mexican habitat is altogether doubtful.

In 1873 Messrs. Salvin and Elliot 4 examined the claims of the various forms of this 
bird to be considered distinct species, and came to the conclusion that only one could be 
admitted ; and now reviewing this decision we are of opinion that it is correct. Comparing 
specimens of approximately the same age and sex from the State of Panama, from 
Guiana, and Southern Brazil, we find no tangible difference whatever between them. 
So far as the bird found within our limits is concerned, it has been called by two 
names before being finally referred to G. hirsuta. The specimens obtained by 
M‘Leannan on the line of the Panama Railway were first considered by Mr. Lawrence 
to belong to his G. affinis of Ecuador’, and the Costa Rica bird was described as new by 
the same author as G. eneus°. Both names now rank as synonyms of G. hirsuta. 
The range of this species covers a wide area, and it embraces the low-lying hot 
districts of tropical America rather than the slopes of the mountain-ranges from Costa 
Rica to South Brazil. In the former country it appears to be rare, but on the line of 
the Panama Railway it is a common bird, frequenting the edges of the forest and 
clearings about the stations of the railway-line.
