The egg was of a warm pinkish ground color, with nu- 

 merous dashes, spots and blotches of purplish red, lilac and 

 lake, the largest spots at the large end, and only smaller 

 dots beyond the middle, although these reached sparingly 

 the small end. It measured 21.5 x 17 mm., and weighed 

 three grams. 



The nestling was leaden brown, with eyes and wing 

 tracts black; the bill black with enormous, milk-white lateral 

 jowls, in width more than twice the length of the bill. The 

 femoral tract showed two rows of feathers, eight flights and 

 five coverts, extending at right angles to the femur. The 

 inside of the mouth was bright lemon yellow, with a milk- 

 white border. The nestling uttered a weak but penetrating 

 squeak. 



The region around the eye in the adult was bare, swol- 

 len and pale bluish-white, becoming quite blue above the ear, 

 where it merged with the brown feathers. The mandibles 

 were black, paler at the tips; the legs and feet were pale 

 pinkish white.

 parrots (Pionites melanocephala) , feeding noisily high up 

 in the top of a great jungle tree on the big sunflower-shaped 

 fruit that hung there, when, from a little beyond, there was 

 a great shaking of branches and a single red howler came 

 swinging along, first with a scramble out onto an overhang- 

 ing branch, then a jump thi-ough mid-air, a hasty grasp at 

 rapidly passing twigs with hand or tail, another scramble, 

 a short run, and then one more jump. This rapid transit 

 soon brought him to the now silent parrot tree up which he
