is wide, thin, dilated anteriorly to the furcula into 

 a pouch an inch and a half long, with a diameter of 

 one incli, its whole length being five inches. At its 

 lower part it is thickened, glandular, and extremely 

 dilated, that portion being directly continuous with 

 the stomach. The latter organ is roundish, some- 

 what compressed, an inch and five-eighths in diameter ; 

 its tendons three-eighths in diameter ; its muscular coat 

 extremely thin, the inner very soft and without rugae. 

 The intestine, w^hich is twenty-eight inches long, has a 

 diameter of a quarter of an inch at its upper part, but 

 gradually contracts, until at the coeca it is only one- 

 eighth across. The coeca are extremely small, being 

 only two-twelfths long, obtuse, adherent, and placed at 

 the distance of two inches from the anus. The pylorus 

 is very narrow, but is destitute of the knob-like valves 

 observed in that of the falcons. The liver is of two 

 nearly equal obtuse-edged lobes, and there is no dis- 

 tinct gall-bladder. 



The eyes are large ; both eyelids feathered and fur- 

 nished with ciliary bristles, so that the projection of 

 the lachrymal bone is not so obvious as in the falcons ; 

 the nostrils large, ovato-oblong ; the aperture of the 

 ear broadly elliptical and large. 



The tarsi, which are anteriorly feathered about a 

 third down, are rather long and slender, and have an- 

 teriorly a series of eighteen rather oblique scutella, of 

 which the lower are smaller, the sides and hind part 

 above reticulated with large hexagonal scales, the mid- 

 dle of the back having about twelve scutella, the lower 

 part small oblong scales. The toes are rather slender, 

 of moderate length, the first with six, the second with
