two yoiuig birds and eggs of the same sub-oider, from Port 

 Keats, Northern Territory. The megapodes, called also 

 scrub and jungle fowl, form nests of huge size by scratching 

 up sand and leaves. The eggs are deposited in the mass of 

 decaying leaves, in holes, some 2 or 3 ft. deep. The fledg- 

 lings, of which skins were exhibited, taken out from a depth 

 oi '2 ft., were able to ily when taken. The nest was about 

 40 yards in circumference. Mr. Zietz, a brush turkey (Tale-
