XIPHOEHTNCHUS. 189 



Hah. Panama, Lion Hill (M'Leannan^). — Colombia ^ Venezuela 6, and Eastern 

 Brazil ^ *. 



Mr. Chapman places the birds from Panama, called by Mr. Lawrence X. lafres- 

 nayanus, with the Venezuelan form of this species under the name of X. venezuelensis. 

 Our single specimen, though rather small, also agrees with Venezuelan examples. 

 But we are unable to distinguish these from other examples from Colombia (Bogota 

 trade skins), or indeed from others from Bahia and Eastern Brazil, which we take to be 

 the true X. trocMlirostris of Lichtenstein. Mr. Chapman separates X. venezuelensis 

 from X. trocMlirostris by the longer bill of the former and the more distinct edges to 

 the feathers of the throat, but the differences are very slight and we cannot think 

 them of specific value. 



X. trocMlirostris just enters our fauna, and the only specimens obtained were 

 shot by M'Leannan at Lion Hill Station on the Panama Railway. Three of these he 

 sent to Mr. Lawrence and one to us. 



Salmon, who took a nest of this or a very nearly allied species at Remedies, in the 

 Valley of the Cauca, Colombia, says the eggs are white and nearly round, and that the 

 nest was placed inside a decayed tree which had been cut off about three feet from the 

 ground and become hollow to the roots, so that the nest had no protection from 

 the rain.

This species may be readily distinguished from X. trocMlirostris by the colour of 

 the bill, which is horn-colour, without any of the red tint so conspicuous a feature in 

 the allied form. The wings and tail are also much darker, but this character is more 

 apparent in specimens from Central America than in the type and other southern 

 examples. 



X. pusillus was described by Mr. Sclater from a trade skin of Bogota make i. 

 Other examples have reached us from that country, and we have received many from
