(type examined). 



[No. 259. Wanumbai. Female.] 



I have compared this specimen with the type in the British Museum and with two 

 other specimens from New Guinea, collected by D'Albertis and Bruijn's men. From all 

 these it differs in the finer vermiculations, and in the somewhat smaller dimensions, and 

 perhaps may belong to a different species ; but we must see some more specimens from 

 the Arrou Islands before we can decide the question. 



The Caprimulgus brachyurus, Rosenb., is a young bird, with the tail incompletely 

 developed.
