26o BRITISH BIRDS, 
and that proved to be a male. Therefore, until a 
Goofander be found, upon dilfedion, to prove a 
female, or two Goofanders to attend the fame neft, 
the doubts refpeding thefe birds cannot be fatisfac^ 
torily removed.’^ 
Although Willoughby defcribes this as the fe- 
male Goofander, yet he expreffes his doubts of the 
matter, from its being, like that bird, furnifiied 
with a kind of large labyrinth, which, he fays, is 
to be found in the males only of the Duck tribe, 
and whence he conjedures that this is alfo peculiar 
to all the males of the Mergi, and that all the fe^ 
males are without it ; but he notices one of this fai 
mily (which at Venice is called Gokall) in which 
this labyrinth, or enlargement of the windpipe was 
wanting. Refpeding the Dun-diver he further ob- 
ferves, that the ftomach of this bird is as it were 
a craw and a gizzard joined together. The upper 
part, refembling the craw, hath no wrinkles or folds 
in its inner membrane, but is only granulated with 
fmall papillary glandules, refembling the little pro- 
tuberances on the third ventricle of a Beef, called 
the manifold, or thofe on the fliell of a Sea-urchin.’^ 
The above figure was drawn from one in full 
plumage and perfedion, for which this work was in- 
debted to Robert Pearfon, Efq. of Newcaftle, the 
:38th of February, 1801.
