Dr. Lath am' j EJJay on the Trachea. 1 or Windpipes of Birds. 103 



The above account is extracted from a DiiTertation on this bird, 

 in trie 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 Eflay. This circumstance, 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 Hcavi- 

 fide, Efq. of Great George Street, who, amongft many curious ana- 

 tomical fubjects, pofieffes a preparation of the parts in very fine 

 condition. 



VI. ANAS SEMIPALMATA— Semipalmated Goose. 



A. grifea, capite collo femoribufque nigris, collari uropygio cor- 



poreque fubtus albis, pedibus femipalmatis. 

 Habitat in Nova Hollandia. 



This feems to be a fpecies not hitherto defcribed ; it is nearly of 

 the fize of the wild Goofe: the bill is brown, and the cere panes 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 Hawkfbury 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 Ikin, before it enters the thorax : its note is laid to 

 be tuneful and melodious ; and it was obferved fometimes to perch 

 on trees, in the manner of the Wbijlling 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, Efq. Lower 

 Grofvenor Street.
