Some of our Central-American specimens are rather yellower beneath than others 

 from Ecuador, but the difference is not always appreciable ; moreover, a Venezulan 

 example is yellower than any of the rest of our series. 



L. squamicristatus was described from Colombian specimens, whence it has since 

 been traced southwards to Central Peru ^. In Ecuador it occurs in many places on 

 both sides of the cordUlera. It is also found in Venezuela, Mr. Goring having met 

 with it on the Cumbre de Valencia. It appears to be absent in the low-lying lands of 

 the Isthmus of Panama, but to occur in some numbers in the more mountainous parts 

 near Calovevora and Chiriqui, and also in similar districts of Costa Rica. In the latter 

 country v. Frantzius says that it is common in the cool forests of the mountain slopes of 

 Quebrada Honda. Hence we infer that it must not be looked for near the sea-level. 



Eraser says that the irides in life are orange, the legs and feet flesh-colour, the biU 

 blackish ^- 



OECHILUS. 



Orchilus, Cabanis in Tschudi's Faima Per. p. 164 (1845) (type Platyrhynchus auricularis, Vieill.) ; 

 Scl. Cat. Birds Brit. Mus. xiv. p. 88. 



Three species are included in Orchilus, viz. 0. auricularis of South-eastern Brazil 

 0. ecaudatus of Bolivia, Peru, and Venezuela, and 0. atricapillus of Costa Eica, The 

 two latter species are somewhat abnormal, having remarkably short tails, whereas the 

 type of the genus {0. auricularis) is not so definitely marked in this respect. 



Orchilus, as represented by the somewhat abnormal 0. ecaudatus, is another departure 

 from Todirostrum, and is mainly distinguished by its very short square tail ; the bUl is 

 similar to that of Lophotriccus, but is longer and rather more arched. Like Todi- 

 rostrum it has no occipital crest.
