width, with very large cylindrical glands arranged so as to form a belt 

 5 inch in breadth. The stomach, efg, is a very large and strong gizzard, 

 brpader than long, and placed obliquely, its length 1 inch, its breadth 

 1;^ inch ; the left muscle 3^ twelfths, the right 5 twelfths thick, the 

 lower muscle very thin but prominent ; the tendons very large ; the 

 epithelium very dense and horny, longitudinally rugous ; the grinding 

 surfaces concave. The proventricular glands are 3 twelfths in length, 

 the upper inclining downwards, the lower perpendicular. The liver is 

 rather small, the right lobe 1 inch 1 twelfth in length, the left divided 

 into two lobes, of which the anterior is 10 twelfths, the posterior 1 inch 

 in length. The intestine, glih, is of great length and width, the former 

 26 inches, its average diameter being 2| twelfths. The duodenum, g h i, 

 curves round the lower edge of the stomach, returns at the distance of 

 4J inches, ascends to the liver, which has two ducts, but is destitute of 

 gall-bladder, then forms seven curves, and terminates in the rectum above 

 the stomach. The coeca, Fig. 2, b c, come off at the distance of 2^ inches, 

 and are 4^ inches in length ; their width at the commencement 3 twelfths, 

 their greatest width 4^ twelfths, their extremity obtuse and convoluted. 

 They are marked with oblique branched ridges on the ianer surface. 

 The intestine at this part is 2 twelfths in width ; the rectum, a b, 2^ 

 twelfths, without cloacal enlargement. 



The trachea is 3 inches 2 twelfths long, flattened ; its breadth at 

 the top 2 twelfths, at the lower part 1 twelfth ; its rings cartilaginous, 

 about 85 ; the lower very large, with a membrane intervening between 

 its two portions. The lateral muscles are strong, but there are no infe- 

 rior laryngeal muscles. The rings of the bronchi are only 10.
