Ornithology of Central America. 
A single specimen only was shot by Salvin amongst the 
rushes on the banks of the lake of Duenas, where it appeared to 
be scarce. 
This apparently hitherto unnoticed Wren rather resembles the 
N. American Cistothorus brevirostris , but is much larger in di¬ 
mensions and more distinctly marked. 
y O 19. Troglodytes aedon (Vieill.). (N. A.) 
Undoubted examples of this bird have been transmitted by 
Mr. Skinner; but it is uncertain whether this agrees with the 
common wren at Duenas, specimens of which were not col¬ 
lected.

A small flock of about twelve were seen in the open land near 
Duenas, about the middle of February. They were apparently 
on passage, and did not remain.

This bird is not uncommon at Duenas, frequenting low bushy 
trees. It seems to extend its range through a great variety of 
temperature, as a single individual was seen in the month of 
February 14,000 feet above the level of the sea, on the summit 
of the Volcan de Agua. It does not remain to breed. 
Specimens from Guatemala agree with those collected by 
M. Salle in the State of Vera Cruz. They are much more 
cinereous than P. ccerulea of N. America, and have no appearance 
of a frontal band in either sex. It is not yet certain whether 
they are anything more than P. ccerulea in winter plumage.
