182 MR. O. SALVIN ON THE BIRDS OF VERAGUA. [ Mar. 24, 
Baird, with some doubt, refers Mexican and Guatemalan specimens 
to Merulaxis griseicollis, Lafr. (R. Z. 1840, p. 103), a species Sclater 
considers, with Lafresnaye himself, to be a Scytalopus (Cat. Am. B. 
p- 168), and to belong to the Pteroptochide. Though not alto- 
gether satisfactory, I must say I think Lafresnaye’s description suits 
the Scytalopus better than the Henicorhina, no mention whatever 
being made of the conspicuous markings on tne sides of the head in 
the present bird. Taking Baird’s list of localities, the evidence af- 
forded by the distribution of this Wren is all in favour of there being 
but one species.

A single specimen in abraded plumage seems to belong to this 
species. The bill, however, is very robust, and the head exhibits 
none of the longitudinal light markings to be seen in C. elegans. As 
regards the colouring of the lower back and uropygium, the chief 
distinguishing character between C. elegans and C. palustris, this 
skin agrees very fairly with the former. The specimen is not in 
a condition good enough to enable me to determine it satisfactorily.

Arcé’s last collection contains three specimens of this beautiful 
species, which are the first I have ever seen. According to Arcé’s 
dissections, both sexes have the interscapular region black ; but in 
the female this character is neither so extensive nor so regular in 
form as in the male.
