the State of Panama, the bird most probably occurs in suitable localities. In the State 

 of Panama it has been found in several places both along the line of railway and in 

 districts lying nearer the Costa Rica frontier *. 



The range of S. mexicanus in South America is generally admitted to be extensive 

 and to reach to the Amazons Valley throughout its length, and even to extend to 

 Bahia, though the latter point requires confirmation. 



Central American examples appear to have the chestnut colour of the breast spread 

 further over the abdomen than is the case with those from South America. Within 

 our limits, birds from the State of Panama are a shade darker than those from Guate- 

 mala, but on the whole the variation is slight for a bird having so wide a range. 



In habits Sclerurus mescicanus resembles some Troglodytidse. It was not seen to 

 climb like other Dendrocolaptidae, but to hop about the brushwood and to scratch 

 amongst leaves on the ground. The cry is shrill, and may be heard at some distance ^.

We have a specimen from Guatemala which agrees fairly with Dr. Hartlaub's 



* There seems some confusion respecting M'Leannan's specimens of Sclerurus, obtained on the Isthmus of 

 Panama. These have been recently re-examined by Mr. Eidgway, and we follow his determination of them. 

 t We are uncertain as to the proper name for the bird from the Isthmus of Darien called by Cassin 



Sclerurus brunneus.

Mr. Eidgway considered the specimen thus named to be young, and it was the only example which he 

 attributed to S. brunneus when writing his monograph of the genus. It is described as having " the throat 

 white, with brown or dusky margins to the feathers," a character better suiting S. guatemalensis than S. brun- 

 neus, the throat-feathers of which are very indistinctly edged with dusky.
