MRS. MAXWELL’S COLORADO MUSEUM. 
CATALOGUE OF THE BIRDS. 
The following is a systematic catalogue of the birds contained 
in the “ Colorado Museum,” prepared by Mrs. M. A. Maxwell, 
of Boulder, Colorado, and by her exhibited at the Centennial 
Exposition held in Philadelphia during the past summer. The 
collection consists of excellently mounted specimens, many of 
which were procured by the lady herself, while all were put up 
by her hands. It illustrates very fully the avian fauna of Color- 
ado, while it bears testimony, not only to the great richness and 
variety which characterize the productions of the new State, but 
also to the success which has crowned the enthusiastic and 
intelligent efforts of a “ woman Naturalist.” 
The collection embraces many species whose occurrence in 
Colorado was wholly unlooked for ; such as Nyctherodias viola- 
cens , Garzetta candidissima , and Tantalus loculator among 
southern species, and Stercorarius parasiticus , Xenia sabinei , 
and CEdemia americana from the high north ; the latter, it will 
be observed, is a strictly littoral species, hence, its occurrence in 
Colorado, the very centre of the continent, is all the more 
remarkable.
