Only one specimen secured, out of two or three of these swifts that were 
flying about over the Ituri River, in company with several examples of 
Chetura cassint. In spite of our long stay in this region, the species was not 
again positively recognized; but Chetura cassini, C. stictilema and C. 
sabinet were all of common occurrence there. | 
Apaloderma minus sp. nov. 
Resembling Apaloderma narina, but decidedly smaller, of different color- 
ation, and with bill less swollen. The serration of the maxilla is less pro- 
nounced. 
The adult male of A. minus is distinguished by the bluer hue of the fore- 
head, throat, and upper breast, which show in certain lights deep violet 
reflections, and by the more scarlet, less crimson color of the remaining 
underparts. In life the naked areas on the cheeks are bright yellow, whereas 
in A. narzna they are light green. 
The adult female differs in the more tawny or ochraceous coloration of 
the breast, which is grayish in this sex of A. narina, although sometimes 
washed with light brown on the upper breast. A greenish gloss on the 
upper breast is more common in females of A. narina. 
In juvenal plumage both species are entirely buff below, the feathers 
more or less tipped with dusky.
