The intestine two feet three inches in length, its widest part 

 two and a half twelfths, the narrowest, tow^ard the rectum, a 

 twelfth and a quarter. The cooca are two slight knobs, one- 

 twelfth in length and diameter. The rectum three inches 

 long, its cloacal portion an inch in width. The gall-bladder 

 oblong, half an inch in length ; the entrances of the cystic and 

 hepatic ducts four-twelfths apart. This individual not having 

 been described, I now take another shot on the 18th May 

 1834. 



The form of the parts is as described in the male. On the 

 tarsus are eighteen indistinct anterior scutella, on the first toe 

 six, on the second eight, on the third twenty-seven, on the 

 fourth fourteen and several basal series. The fourth quill is 

 longest, the fifth little shorter ; the tail a little rounded, the 

 lateral feathers being half an inch shorter than the longest. 

 The bill and claws are light blue at the base, black toward the 

 end ; the cere and supraocular edge light greenish-yellow ; the 

 iris orange ; the feet yellow-orange. The general colour of the 

 upper ]:)arts is brownish-grey ; the feathers of the hind-neck 

 white at the base, the scapulars and inner secondary coverts 

 with two large concealed bands of the same colour. On the 

 tail are four dusky bars, and an obscure basal bar, the tip 

 greyish-white. The quills are obscurely barred with dusky, 

 and have their inner webs in the intervals yellowish-white, 

 unless toward the end. The general colour of the lov>'er parts 

 is greyish-white, transversely marked with narrow bars of 

 dusky-grey and brownish-red, each feather on the breast hav- 

 ing five bars, the throat with longitudinal lines of deep brown. 

 The abdomen is less barred, and the low^er tail-coverts are 

 white ; the lower wing-coverts reddish-white, barred with 

 dusky ; the lower surface of the quills and tail-feathers pale 

 grey, tinged with red, and barred with dark brown.
