of the Goofander.” The following circum-

the Goofanders. 2d, The Dun-divers are all lefs 
than the Goofanders, (the largeft I have feen being

the Dun-diver is confiderably longer than the creft

Dun-divers have been found, upon diffediori, to be 
males. 5th, The neck of the largeft Dun-diver, 
and which has proved to be a male, is nothing like

26th of December, 1783, I diffed:ed a Dun-diver, 
which was rather more than three pounds in weight ; 
its length was twenty-feven inches, and its breadth 
thirty-five inches. It proved to be a male : the , 
teftes, though flaccid, were very diftinQ:, and about 
half an inch in length. In the middle of January , 
1786, I received two Dun-divers, both of which I 
difledted : the firft was a fmall one, about two

longer, and its belly of a fine yellowilh rofe-colour : 
it was a male, and the teftes were beginning to 
grow turgid. I have diffected only one Goofander,
