Though this species has been traced as far north as Greytown in Nicaragua, and has 
also been noticed in the neighbourhood of Chiriqui, it is apparently a rare bird in our 
region, whence at present we have only one Chiriqui specimen. This agrees closely 
with an example from Bahia, and we have no doubt as to the identity of the species, 
though its range is so great, and, so far as we know at present, interrupted in the 
Amazons region, whence no examples have yet reached us. 
Mr. Lawrence’s Hlainea semiflava we have no doubt belongs here. Some years ago 
we examined his type and came to this conclusion, which was confirmed more recently 
by a re-examination and comparison of the type with our own and Mr. Sclater’s 
examples. 
In Brazil C. flaveola appears to be more common. Natterer obtained five specimens, 
and speaks of having met with a small flock at Goiaz in the month of August. 
ORNITHION. 
Ornithion, Hartlaub, J. f. Orn. 1858, p. 35 (type O. inerme, Hartl.); Scl. Cat. Birds Brit. Mus. 
xiv. p. 125. 
A genus of four species of small size and dull colour, the species of our region being 
of a brownish plumage hardly relieved by yellowish beneath. The rictal bristles are 
but feebly developed and less conspicuous than in Elainea, to which Ornithion has 
some affinity. The bill is much compressed, the sides concave, the width at the gape 
being about £ the length of tomia, the culmen is gradually arched from the forehead ; 
the nostrils are in the middle of a membrane, and thus differ from the foregoing 
genera, but resemble those which immediately follow; the tarsi are long, and the feet 
comparatively strong. The wing is short and rounded, offering no peculiar feature ; 
the tail is short and square at the end, = $ wing, wing = 3 tarsus.
