a specimen of what he may expect when he is fairly Launched into 

 the literature of Ornithology. 



One specimen of the species now described is in the collection of the 

 Expedition, and was obtained at the Sooloo Islands, but we have no 

 notes relating to its habits or history.

Form. — Small for this genus ; head witli a crest of recurved feathers ; 

 bill large ; wing long, third quill longest ; tail moderate, wide ; 

 tarsus very short ; toes long, beneath padded and flattened. Space 

 around the eve and on the throat, bare. 



Dimensions. — Total length (of skin), about twelve inches; wing, 

 nine inches; tail, four and a half inches. 



Colors. — Inferior coverts of the tail, rich reddish-orange, nearly

 edges of the quills, pale yellow, the latter readily seen, viewing the 

 wing from below. All other parts white. Bill and feet light. 



Of this species, remarkable for its small size when compared with 

 the large congeneric species of Australia, specimens were obtained by 

 the naturalists of the Expedition at the Philippine Islands. 



BufFon's description of this species is apparently taken from Brisson, 

 and his plate (as cited above), may be safely suspected, at least, of

 appears to be little known to naturalists. Specimens are in the collec-
