Toe have lateral appendant membranes, reaching their whole length. 



The Wind-pipe at the divarication ends in a certain great, ftrong,bony vefi'el, which 

 we are wont to call a Labyrinth 3 whence proceed the two branches tending to the 

 Lungs. 



This Bird hath not two blind guts, after the manner of other Birds, but only one 

 fhort blunt one, [ yet in one bird of this kind we found two.] The Wind-pipe is 

 faftned to the upper angle of the Merry-thought by a tranfverfe ligament, and then 

 afcends upward to the Labyrinth. It feeds upon fifties. 



The Albellus aquaticus of Aldrovand, as it feems to me, differs not from this bird, 

 for both the figure, and all the marks he gives of it, agree 3 only he makes no mention 

 of thecreft, perchance it was a young bird he defcribed. 



There is in this kind alfo fo much difference between the Sexes, that the Writers of 

 the Hiftory of Birds have taken the Male and Female for different forts. The Fe- 

 male is defcribed by Gefner under the title of Mergus glaaalk, which Mx.Johnfon 

 Englifheth the hough-diver. It was fent us by Mr. Dent from Cambridge by the name 

 of a Smew. 



In the Female the whole Head and the Cheeks are red or fulvous : The Throat 

 white. On the beginning of the Breaft above the Craw there is feen as it were a col- 

 lar of a darker or brown colour : It hath no Creft. All the upper fide except the 

 Wings is of a dusky afh-colour or brown. About the middle of each Wing are two 

 tranfverfe white lines. In other particulars it agrees well enough with the Male. 



It hath a great Gall 5 oblong Tefticles : The Guts have many revolutions. The 

 Stomach larger than in granivorous birds, lefsmufculous, filled with fifties,in the birds 

 we opened.

 O/Douckers in general 



Ouckers have narrow, ftreight, fharp-pointed Bills : Small Heads, and alfo 

 k fmall Wings : Their Legs fituate backwards near the Tail, for quick fwim- 

 ming, andeafier divings broad flat Legs 5 by which note they are diftin- 

 guifhed from all other kinds of birds : Broad Claws like humane nails. 

 Of thefe Douckers there are two kinds, The firft is of fuch as are cloven-footed, but 

 fin-toed, having lateral membranes all along the fides of their Toes, and that want 

 * Have the the Tail 3 the fecond is of thofe that are whole-footed and * caudate, which do near- 

 TaiL ly approach to thofe birds we call Trida&yU, that want the back-toe. Thefe are not 



without good reafon called Douckers, for that they dive much, and continue long 

 under water, as foon as they are up dopping down again.
