98 LANlIDiE. 



feathers broadly tiiiped with white ; bill whitish blue. Total 

 length 13-5 inches, culmen 2-05, wing (J-SS, tail 5-8, tarsus 1-4. 



Adult female. Very similar to the male, but differing considerably 

 in the back, which is black with more or less distinct spots of pure 

 white, larger near the scapulars. Total length 13 inches, culmen 2, 

 wing 6-3, tail 5-3, tarsus 1'35. 



Young. Like old female, but browner, and having many of the 

 feathers edged with white or whity-brown ; the back nearly entirely 

 black, with a few triangular spots of white. 



Ohs. There is no doubt that, as Dr. Meyer has stated, the increase 

 of white on the back is a sign of age in these birds. There is little 

 variation in the specimens from different localities, excepting in a 

 very old male from Waigiou, a male from Port Moresby, and one 

 from New Guinea, which have a little black spot near the base of 

 the outer tail-feathers. Two specimens from New Guinea have the 

 terminal half of the tail-feathers white, except the central pair.
