" The nests found on the 28th of April and the 8th of June, 1873, 

 were composed of an irregular layer of moss, mixed with a little wool, 

 sprigs of dry herbs, small roots aud branches, on this layer is arranged 

 the nest of wool and different kinds of hair ; rarely have they any 

 feathers. All this construction is heavy and solid ; the interior is rather 

 deep but carefully arranged. Height 4-5, breadth 13, diameter of the 

 interior 4-5, depth 2'5 centim. M. Jelski found them under thatched 

 roofs. 



" The eggs are greenish white and present different varieties of mark- 

 ing, some have a large ring composed of very small reddish spots on the 

 upper end, and darker ones scattered over the surface, while others are 

 more spotted and streaked with blackish-brown.
