CATALOGUE OF TROCHILIDE IN THE COLLECTION OF THE 
UNITED STATES NATIONAL MUSEUM. 
By ROBERT RIDGWAY. 
The following catalogue enumerates all the species of Humming Birds 
which are contained in the collection of the National Museum, with the 
localities represented, the latter being in many cases additional to those 
given in standard text-books relating to this family of birds. The chief 
aim of the list is to show what species are wanted to complete the col- 
lection, and exchanges to this end are respectfully solicited. Many of 
the species of the list are represented by an incomplete series of speci- 
mens, often by a single skin only, and of these additional specimens are 
desirable, especially if from a locality not mentioned in the list. Such 
species are indicated by an asterisk prefixed to the name. 
The names' and numbers correspond with those of Ellot’s “ List of 
Described Species of Humming Birds,” published by the Smithsonian 
Institution.’
