In Cuba A. hyperboreus seems to be a regular annual visitant, 

 and is common, remaining in the island from October until the end 

 of March. It has only been observed in Jamaica when the winter 

 in the north has been severe.

Dr. Bryant reports that, some years before his visit to Inagua in 

 18.59, a flock of this Goose visited the island, when every individual 

 was killed by the inhabitants. Dr. Gundlach, who maintains the 

 distinctness between this bird and A. hyperboreus, says that it is of 

 rare occurrence in Cuba, but that it arrives along with the migratory 

 flocks of the allied species.

Not common, but not so rare in Cuba as A. ccerulescens, where, 

 however, it is stated to be a regular winter visitant, remaining in the 

 island from October till the end of March. Col. Grayson obtained 

 it near Mazatlan, N.W. Mexico.

Bernicla is a widely extended form, with four or five representatives 

 in North America, of which one reaches the Neotropical region as an 



* Some attempts have recently been made to revive Branta of Scopoli (Ann. 

 I. H. N. p. 67) for this genus. But Branta of Scopoli is an artificial group 

 composed of species which have no sort of natural affinity, and is therefore 

 to be cancelled. Besides Branta is generally used for Fidk/ula rufina, and it 

 would create great confusion to substitute it for the universally accepted term 

 Bernicla.
