sionally laying as many as nine eggs in a clutch. The brent goose, on the other 

 hand, breeds on the sides of slopes on the bare space left between the line of snow 

 and the sea ice; the four eggs being deposited on a bed of grass, moss, and saxi- 

 frage overlain with down. Occasionally the nest of another bird is adopted by some 

 of the members of this genus. All the brent geese are readily tamed, and breed 

 in confinement, several of the species crossing with one another. 



The brent geese of the Southern Hemisphere differ more or less 

 markedly from their northern cousins, and some or all of them have 

 accordingly been separated (as Cloephaga) from the genus Bernicla, 

 although we follow Mr. Sclater in including the whole of them under that name.

Several of these lack the black heads and necks of the northern species, and in some, 

 such as the upland goose (B.magellanica), ranging from the Falkland islands to 

 Chili, and the kelp goose (B. antarctica) of the Falkland islands and Patagonia, 

 the male is mainly white, while the female is mottled brown. In other cases, how- 

 ever, as shown in our figure, which is taken from hybrids between the upland goose 

 and another species known as B. dispar, the difference between the two sexes is less
