dun, the two shades seeming to struggle for supremacy. The cream prevails on the neck, the dun on the other parts; but even the neck is of a much duller shade than in the bird just described (No. 1). There are parts of the breast where the original sombre hue, a little softened, encroaches, cloudily, upon the lighter surface. These two birds cannot, certainly, be described as more or less handsome, merely, in the same colouring. The lighter surface, at any rate, is plainly different in shade, also its amount and distribution, though in a less degree.
(3) Another bird is much like this last one (No. 2), but there is, here, a distinct, broad, dunnish space, dividing the throat and breast parts, making, of course, a very palpable difference.
(4) Another bird—one of two standing together—is the common uniformly dark form, except that the neck and throat just below the head is, for about an inch, very much lighter, making a considerable approach to cream without quite attaining it. This light part is conspicuous in the one bird—this that I have been describing (No. 4)—but not in the other (No. 5) that it is standing by.
(5) This other one might pass for the ordinary dark form, but on examining it through the glasses a lighter, though less salient, collar is distinctly visible.
(6) In a third bird, not far off these two (Nos. 4 and 5) the whole colouring, from immediately below the crown of the head—which seems always to be black or very dark—is of a uniform brown-drab or
