The Female is considerably larger than the male, but otherwise 

 similar. 



In winter the upper parts are ash-grey tinged with brown, each 

 feather with a central dusky line. 



In a female preserved in spirits, the roof of the mouth is flat, with 

 the edges a little prominent, and two medial series of reflected papillae. 

 The tongue is 10;^ twelfths long, slender, papillate at the base, con- 

 cave above, rather obtuse and somewhat jagged at the extremity, horny 

 in nearly its whole length. The extremity of the upper mandible is 

 somewhat scrobiculate ; the lower mandible deeply concave. The oeso- 

 phagus, which is 2^ inches in length, is very slender, being scarcely so 

 wide as the trachea, its diameter nearly uniform, and about 1^ twelfth. 

 The stomach is elliptical, a little compressed, ^ inch long, 4^ twelfths 

 broad, its lateral muscles moderately developed, its tendons large, the 

 epithelium tough, longitudinally rugous, and of a reddish-brown colour. 

 It contains particles of quartz and small seeds. The intestine, of 

 which the diameter is generally 1 twelfth, measures 10 inches in length ; 

 and the coeca, which come ofi" at the distance of f inch from the extre- 

 mity, are 1 inch long, and three-fourths of a twelfth in their greatest 

 diameter. 



The trachea, which is 1 inch 10 twelfths long, passes to the right 

 side of the neck, along with the oesophagus, as in all birds destitute of 

 crop, is considerably flattened, and varies in diameter from li twelfth to 

 I twelfth. The rings are about 98 ; the bronchial half rings about 15. 

 The lateral muscles are strong, and terminate in the sterno-tracheal, 

 at the distance of a twelfth and a half from the inferior larynx, which 

 is destitute of any other muscle than a slender continuation of the con- 

 tractor, which goes to the first bronchial ring.
