It has long been the practice to associate d’Orbigny’s Myrmothera ménétriési! with 
this widely spread species, though no specimens have been included in recent collections 
from Bolivia, the origin of the types. The range of thé bird seems to be practically 
unbroken from Eastern Guatemala southwards through Central America, Colombia, 
Ecuador, and Peru to the confines of Bolivia, so that d’Orbigny’s bird may well be the 
same as that so well known to us. Should, however, it prove different we still have 
plenty of names for the northern bird, for Mr. Lawrence described the male as Formi- 
civora schisticolor 11, and the female as Myrmotherula modesta°, both Costa Rica birds. 
A young male from Guatemala has also been named M. nigrorufa by M. Boucard ®. 
In Guatemala WZ. ménétriési is not a common bird, and is restricted in its range to 
the forest country of Vera Paz lying to the northward of the town of Coban. We were 
long in doubt what this bird could be, for our collectors only sent us female examples ; 
on the receipt of an adult male from the same district the question of its identity was 
decided. In Costa Rica and the adjoining portion of the State of Panama this Myrmo- 
therula is common, but it appears to be absent from the line of the Panama Railway, as 
it was unrepresented in M‘Leannan’s collections; Salmon, too, did not meet with it. 
In Western Ecuador both Fraser and Stolzmann met with it, the latter collector at 
Chimbo °, The specimens obtained by him were noticed by Count von Berlepsch to 
differ slightly in dimensions and colour from Panama examples. So far as the specimens 
before us indicate, the grounds for separation are hardly tangible. 
Little has been recorded of the habits of this species. Fraser states that its food 
consists of insects; and Stolzmann, who found it rather common at Huambo in Peru, 
says that it travels in small flocks near the ground, where it appears to seek the places 
in the forest free from bushes and small trees, and where the ground 1 is scantily covered 
with grass °. | ’
