This likewife is a bird of fome peculiarity in refpecl: to the trachea, 

 which is pretty flout, and the rings in proportion : it partes in a 

 ftraight direaion to the bottom of the neck, at which part it lofes its 

 round form, and becomes fomewhat broad and flat ; it then turns 

 backwards and upwards for more than an inch, when it doubles 

 again forwards and downwards ; after which it enters the cavity of 

 the breaff, and is diftributed by its two portions into the lungs.— 

 This circumftance takes place at the front of the keel of the fter- 

 num or breaft-bone, but does not enter into the keel itfelf, as in the 

 three following fpecies.

 fubjea given by Dr. Parfons; it Is alfo reprefented in the Plate re- 

 ferred to in Pitfield's tranfiation of Memoir es pourfervir a VHiJioire des 

 Animaux. The firft of thefe I have thought right to copy (fig. 2 .) 

 and I have added alfo the figure of one which belonged to a bird in 

 my own colleaion (fig. 3.), from which it differs not a little :— but I 

 find that this part of the trachea is apt to vary in different fpecimens ; 

 for a fecond figure, engraved in the fame Plate of Pitfield, (hews the 

 tend to be very fmall, appearing like a mere twift only ; from which
