Dr. LaruAm’s Effay on the Trachea or Windpipés of Birds. 103 
The above account is extraéted from a Differtation on this bird, 
in the Memoirs of the Academy of Sciences; but no anatomical 
figures accompany it, although a good reprefentation of the bird 
itfelf is given at the end of the Effay. This circumttance, however, 
is the lefs to be regretted, as I have been favoured with the two 
views annexed, from the rich and elegant Mufeum of John Heavi- 
fide, Efq. of Great George Street, who, amongft many curious ana- 
tomical fubjeéts, poffeffes a preparation of the parts in very fine 
condition. j 
VI. ANAS SEMIPALMATA~— SemipaLMATED Goose, 
_ A. grifea, capite collo femoribufque nigris, collari uropygio. cor- 
poreque fubtus albis, pedibus femipalmatis. 
Habitat j in Nova Hollandia. 
‘This feems to be a fpecies not hitherto defcribed; it is nearly of 
therfize of the wid Googe: the bill is brown, and the cere paffes on 
each fide to the eyes; ‘the head, neck and thighs are black ; a col- 
lar of white encircles the lower part of the neck, and the rump and 
under-parts are alfo white; the legs are red, and the toes only web- 
bed half-way from the bafe. 
This is met'with near Hawk{bury river, in New South Wales, in 
flocks, and is there called New South Wales Goofe. It is peculiar in 
that the windpipe forms. feveral beautiful circumvolutions.on the 
breaft,-under the fkin, before it enters the thorax: its note is faid to 
be tuneful and melodious; and it was obferved fometimes to perch 
on trees, in the manner of the Whifiling Duck, 
I was favoured with a fight of a drawing of the bird, added to 
the above account of its manners; at A. B. Lambert’s, Efg. Lower 
____ Grofvenor Street.
