GLATJCIS. 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 Qlaucis is very extensive, including nearly the whole of tropical 

 America from Costa Eica 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 ^ 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 Eailway were first considered by Mr. Lawrence 

 to belong to his G. affinis of Ecuador 7, and the Costa Eica bird was described as new by 

 the same author as G. oeneus ^O- 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 

 Eica to South Brazil. In the former country it appears to be rare, but on the line of 

 the Panama Eailway it is a common bird, frequenting the edges of the forest and 

 clearings about the stations of the railway-line.
