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 cordillera. 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. 
Fraser says that the irides in life are orange, the legs and feet flesh-colour, the bill 
blackish ?. 
ORCHILUS. 
Orchilus, Cabanis in Tschudi’s Fauna Per. p. 164 (1845) (type Platyrhynchus auricularis, Vieill.) ; 
Scl. Cat. Birds Brit. Mus. xiv. p. 88. 
Three species are included in Orchilus, viz. O. auricularis of South-eastern Brazil, 
O. ecaudatus of Bolivia, Peru, and Venezuela, and O. atricapillus of Costa Rica. 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 O. ecaudatus, is another departure 
from Todirostrum, and is mainly distinguished by its very short square tail; the bill is 
similar to that of Lophotriccus, but is longer and rather more arched. Like Todi- 
rostrum it has no occipital crest.
