Read Jan. 17, A Ccording to your requeft, and by 
*7 54- ^~\ your affiftance, I have drawn up a 
brief account of the fowl, called a pheafant in Pen- 
fylvania, in order to lay it, together with the birds, 
before the Royal Society. 
The coloured print, Plate XV. reprefents what is 
called the pheafant in Penfylvania and other provinces 
of North America, tho’ it rather belongs to that genus 
of birds, which in England we call heathcocks, moor- 
o-ame, or grous. It is near as big as a pheafant, of a 
brownilh colour on the head and upper lide, and 
white on the bread; and belly ; beautifully variegated 
with lighter and darker colours on the back, and 
fpots of black on the under fide. Its legs are fea- 
thered down to the feet, which will appear by the 
bird preferved dry, here prefent, as well as by the 
print in miniature. As this bird is, in my judgment, 
wholly unknown to the curious of our country, I 
R r r 2 rfiall.
