but when disturbed, or whilst flying, he makes 

 a repeated noise of cuck, cock. They are 

 most common in winter at Albany Fort. 

 Before I leave the genus of grouses, I must 

 observe that their feet have a peculiarity, 

 taken notice of by kw authors; the toes 

 m several species, have on each side a row 

 of short flexible teeth, like those of a comb; 

 so that the toes appear pedinated. The 

 species, which are known to have such peai- 

 nated toes, are, 



1. The great Cock of the Wood, Te/rao 

 C/roj^a/lus, Linn. 



2. The Black Cock, T. Tetrix, Linn. 



3. I'be Spotted Grous, J T. Canadensis, 

 ^^"^ \T.Canace,Ux,xi, 



4- The Ruffed Grous, T. Umbcllus, Linn. 



5. The Shoulder-knot Grous, T. Tomtits, 

 Linn. 



6. The Pheasant Grous, T. Phasianellus. 



7. The Hazel Hen, T. Bonasia, Linn. 



8. The Pyrencx-an Grous, T. Alchata, Linn. 



This is a circumstance, which ought to be at- 

 tended to in all other species of grouses, as it 

 may in time afford a distinguishing charader 

 for a division in this great genus ; the ptar- 

 migan, or r. Lagopns, Linn, is without these 

 teeth.
