AVIFAUNA OF LAYSAN, ETC. 



mistake is possible, since I have before me twenty-six carefully sexed specimens, and 

 Palmers observations (who often saw them building nests and feeding their young) leave 

 no doubt that his "adult females" are fully aged birds. Therefore Cabanis's name 

 is most characteristic. 



Total length about to 5 inches; wing in males 27 to 2*81, in females 26 to 2"72 ; tail 

 1-85 to 2 ; tarsus 0*8 to 0*86 ; culmen in males 0"6 to 0*65, in females 056 to 65, mostly 

 shorter than in males. 



Hab. Island of Oahu. 



Palmeii found this bird only in the upland region in the district of Wailua, on the south- 

 west side of the mountains, at elevations of 1500 feet to the top of the range. In habits 

 it much resembled the species of the genus found on the other islands. It was not at all 

 rare, and I received a fine series in all stages of plumage. 



Wilson says : — " This species is peculiar to the island of Oahu, and is fairly common in 

 the district of Halemanu (house of the birds), where there is still some forest remaining." 



Wilson obtained only immature birds (see ' Ibis,' 1890, p. 186).
