hut when disturbed, or whilst Hying, he makes

 most common in winter at Albany Fort. 



IK lore I leave the genus of grouses, I must 

 observe that their feet have a peculiarity, 

 taken notice of by few authors ; the toes, 

 in several species, have on each side a row 

 of short flexible teeth, like those of a comb; 

 so that the toes appear pectinated. The 

 species, which are known to have such pecti- 

 nated toes, are, 



1. The great Cock of the Wood, Tetrao 

 Urogallus, Linn. 



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



3. The Spotted Grous, ( T. Canadensis, 

 and \ T. Canace, Linn. 



4. The Ruffed Grous, Z! Umbellus, Linn. 



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

 Linn. 



6. The Pheasant Grous, T. Phasianellus. 



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



8. The Pyrenaean 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 character 

 for a division in this great genus ; the ptar- 

 migan, or T. Lagopus, Linn, is without these 

 teeth.
