Ornithology of Central America. 9 



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 brevirosti'is , but is much larger in di- 

 mensions and more distinctly marked. 



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 Dueiias, specimens of which were not col- 

 lected. 



Fam. IV. ALAUDIDiE. 



20. Anthus ludovicianus (Gm.). (N. A.) 



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 Dueiias, 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. carulea 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. carulea in winter plumage.
