tatiug my work, perinittiug me with great kindness and liberality to 

 consult and use their valuable manuscripts. It is a pleasant duty for 

 me to hereby acknowledge publicly my gratitude. 



The present catalogue is only the initial step to a more extensive 

 work on the birds of Mexico, which the Geographical and Exploring 

 Commission intends to publish at some future time. 



It will be perceived that the rules of nomenclature adopted by the 

 ^'American Ornithologists' Union " have been followed, while Messrs. 

 Sclater and Salvin's " jSTomenclater Avium Neotropicalium" has been 

 adhered to as regards the sequence of the families. The sex, locality, 

 and date of each specimen have been noted with great care at the 

 time of collecting, and in case where any doubt has arisen as to the ac- 

 curacy of a particular statement caused by some unavoidable accident, 

 it has been entirely suppressed or marked with a query; all other state- 

 ments not thus marked are entirely reliable.

[An adult (?) female from Teziutlan, State of Puebla (November, 1884), 

 is in general appearance much like an Orizaba specimen in the National 

 Museum collection (No. 37472, F. Sumichrast), but difiers as follows : 

 The whitish portions of the plumage incline more decidedly to dull buff 

 or light Isabella color, except the edgings on basal half of the outer 

 webs of the secondaries and the patch at base of the primaries, which 

 are quite iiure white; the lighter streaks of the head and neck are 

 broader and more distinct. The differences are perhaps seasonal, the 

 Orizaba specimen being apparently in spring or summer plumage.
