der than the Song Thrush. Its bill is of the same form but 

 stouter, its outlines more convex. The oesophagus is three 

 inches and a quarter in length, of nearly uniform diameter ; the 

 proventriculus measures five-twelfths across. The gizzard is ob- 

 long, compressed, an inch and a quarter in length ; its muscular 

 coat thin, the right tendon much larger, the cuticular lining 

 rugous. The intestine is eighteen inches long, at its upper 

 part five-tw^elfths in diameter, and gradually diminishing to 

 two and a half twelfths ; the coeca cylindrical, three-twelfths 

 long, and one inch distant from the extremity. 



The nostrils are elliptical, a twelfth and a half in length ; 

 the eyes of moderate size, their aperture two-twelfths ; that of 

 the ear three-twelfths. The feet are stouter than those of the 

 Song Thrush, and the claws much longer ; in other respects 

 they are similar. 



The plumage is soft, rather blended, slightly glossy, the 

 feathers oblong and rounded ; those of the loral space and throat 

 bristle-pointed ; a few strong bristle-feathers along the base of 

 the upper mandible. The wings are rather long, of eighteen 

 quills ; the first extremely small, the fourth longest, the third 

 little shorter, the second and fifth about equal ; the outer 

 primaries tapering but rounded, the third, fourth, and fifth 

 cut out on the outer web towards the end, the rest and the 

 secondaries broadly rounded with a minute tip. The tail is of 

 ordinary length, even, the feathers rather narrow, and rounded, 

 but suddenly tapering to a point. 



The bill is brownish-black above, and on the end of the lower 

 mandible ; its basal half, and the edges of the upper orange- 

 yellow. The iris is brown. The tarsi are pale flesh-coloured, 

 as are the toes, which are tinged with brown, the claws dusky, 

 but orange beneath. The general colour of the plumage of the 

 upper parts is deep hair-brown inclining to olive, darker on the 

 head, paler on the rump. The quills are deep brown, their 

 outer webs yellowish-brown ; some of the secondary coverts 

 and the three last secondary quills are tipped with greyish- 

 white. The tail is wood-brown, the outermost feather with a 

 white spot on the inner web at the end. The loral space is 

 blackish-brown. From the nostril over the eye, and extending
