rocks, only a few inches above the more level earth, and was com- 
posed of dry leaves, strips of bark, and other fine vegetable fibres, 
and lined with some long horse hair; when placed side by side with 
that of M. varia previously described, I made this comparison of 
the nests and their sets of eggs, after the latter are blown; the nests—
