ORDER GALLING. 119 



followed the oesophagus as far as the aperture of the thorax, 

 mounts over the right great pectoral muscle at some distance 

 from the crest of the sternum, continues its direction over 

 the entire length of this muscle, forms a curve there in pass- 

 ing to the distance of two lines behind the sternum over the 

 tunic which retains the entrails ; it then proceeds the length 

 of two inches and a quarter over the left pectoral muscle, 

 there makes a turn on the side of the sternum, passes anew 

 behind this bone above the first curve, then turns anew, fol- 

 lows its direction over the right pectoral on the side of the 

 crest of the sternum, and passes over the right clavicle into 

 the cavity of the thorax. On each side of the trachea is a 

 muscle which serves to lengthen or shorten it. The tube 

 adheres in its entire length to the pectoral muscles by a very 

 fine cellular tissue, and is immediately covered by the skin. 

 The lower and upper larynx do not differ from the same 

 parts in the peacock, but a very apparent socle is found at 

 the bottom of the upper larynx, at the aperture of the glottis. 

 The tube of the trachea is composed of slender rings, dis- 

 tant from each other about two lines ; the space between each 

 ring is membranous. 



We are assured that the female of Crax Pauxi has the 

 trachea conformed precisely in the same manner as the male. 



This bird in its wild state is a native of Mexico. The 

 greatest number of individuals imported into Holland, came 

 from the colony of Curassow. 



The Ourax Mitu, Pauxi Mitu, Tem. has been repeatedly 

 confounded with the Hocco Mitouporanga, or Crax Alector 

 It bears, however, all the marks of belonging to the present 

 genus. It has the corneous elevation on the base of the bill, 

 forming one and the same piece with the upper mandible. 

 Its nostrils are placed at the base of the upper mandible 

 behind this protuberance, and are partly covered by a mem- 

 brane furnished with small feathers. In fine, it possesses all 

 the characters of a genuine Pauxi.
