to 3 twelfths; the proventriculus, b c, 

 is 5 twelfths in breadth, its glandular 

 belt 6 twelfths. The stomach, c d e, 

 is a very strong muscular gizzard, 

 placed obliquely, of an elliptical form, 

 11 twelfths in length, 9^ twelfths in 

 breadth. The proventricular glands 

 are large, nearly globular, ^ twelfth 

 in diameter. The muscular coat of 

 the stomach is rather thin, the thick- 

 ness of the lateral muscles being 2 

 twelfths; the epithelium dense, tough, 

 dark red, with three longitudinal 

 rugae on each side. The contents of 

 the stomach are remains of insects, 

 larvae, and especially legs of grass- 

 hoppers. The intestine, efg h ij, 

 is of moderate length and width, the 

 former being 12 1 inches, the latter 

 averaging 2^ twelfths. The duode- 

 num, ef, curves in the usual manner 

 at the distance of If inches, and is 3 

 twelfths wide. The coeca, i, come 

 off at the distance of H inches from 

 the extremity, and are 3 twelfths in 

 length, 1 twelfth in width, and obtuse; 

 the cloaca, j, is small and of an oblong 

 form, its breadth 5 twelfths. 



The trachea is 3 inches long, flat- 

 tened, firm, of the nearly uniform 

 width of 2 twelfths. The rings are 

 68, with two dimidiate, rather broad 

 and firm. There are four pairs of 

 inferior laryngeal muscles besides the 

 sterno-tracheal, and the lateral mus- 

 cles are of moderate size. The 

 bronchi are rather narrow, of 18 half 

 rings.
