 drawn. A few liad the sense to hite at the luinds in phu-e (»f the gun-barrel. Tin v 

 hissed like the Donu-stie (Joose, and had a very hoarse, croaking voice. 



The egg is said to measure 2.00 by l.SO inches, some being e(|iuilly rouiuled at botli 

 ends, while others are a little pointed at one end. Tlu' color is a bluish green iiisidr, 

 but cov(!red oiitside with a dry rough white coating, showing the color of tlie interior 

 through it. The young were at tirst covered with a liiu' white down, but the featlicis 

 afterward came cmt of an ash-eolor. The seasons of incubation did not appear to lie 

 regular. At Enderby's Island these birds were luitehing in January, and at otiur 

 places in intermediate seasons. This species is also referred to by Dr. Pickering us 

 being abundant at Gardner's Island, and in other places. 



Eggs of this bird, obtained in the Itahamas by Dr. Hryant, are now in the Smith- 

 sonian Collection (No. 1711i). They are of a uniform dull white color, and measure 

 2.45 by 1.70 inches ; one egg (No. 2438) measures 2.55 by 1.75.
