In this beautiful Hand- grouse, we see, if such an 
expression may be used, a more perfect form. Tike 
form of the bird is strong but light, the wings long 
and ample. The tarsi feathered only in front, and 
the feet evidently adapted for running. We have, 
however, the same prevailing colour of grey and yel-

prevails among them. The belly of the male is deep 
brownish-black, the throat is marked with a spot of 
the same colour, and below the breast there is ano-

lias derived his trivial name. The female is of the 
same general tint. The dark parts of the under 
plumage are paler, and the patch on the throat is 
wanting, but apparently replaced by another of 
grey, while the head, breast, and upper parts are 
covered with brownish-black bars and crossings.
