hidden away in the thick rank undergrowth. The nest is a 

 loosely constructed ball of dead leaves, lined inwardly with 

 fine roots, and the entrance is often somewhat hidden with 

 fresh green moss stuck in the nest. The eggs are three, and 

 glossy white. The nest was taken on the 17th January.

The native name is ''Konkut Landak.^^ (porcupine). Kon- 

 kut is the native name of all Timeliine birds ; the name 

 " landak " is applicable to the long white-stemmed feathers 

 which stream from the sides and back. 



Bill and feet black ; skin round the eye and bare space on 

 the sides of the neck dark French blue. These bare spaces are 

 also found on the neck of Stachyris maculata, which has 

 also long feathers on the back ; so perhaps these genera are 

 only slightly removed.]

Sometime since Mr. Sclater obtained from the Royal Society 

 a grant of money for the purpose of acquiring specimens 

 of the young of the Hoatzin ; for some remarkable statements 

 concerning the development of this bird, lately published in

 structure desirable. Mr. Quelch, the Superintendent of the
