A single specimen is in the collection of the Expedition, which was 

 obtained in Oregon. This remarkable and handsome little species is 

 now frequently brought in collections from Western North America, 

 though usually from California. 



2. Antrostomus OCELLATUS [T>icTnidi). 



Caprimulgus ocellatus, TscH. Consp. Weigm. Archiv. 1844, p. 268.

This handsome and strongly characterized species appears to be 

 peculiar to the western countries of South America. Like the pre- 

 ceding, it is one of the smallest of the birds of its genus, and perhaps 

 ought to be regarded as presenting a subgeneric type. Specimens in 

 the present collection are from Peru, in which country the species was 

 originally discovered by the distinguished author above cited. 



Though placed by us at present in the genus Antrostomus, this bird 

 is different in color from the North American species of this genus, 

 and may be the type of a peculiar subgeneric group. Specimens in 

 the collection of the Expedition are in excellent plumage and preser- 

 vation.
