362 MESSRS. SCLATER AND SALVIN ON L^P^'- 4, 



occasional winter visitant, and with six peculiar species in Antarctic 

 America. 



1. Bernicla canadensis. 



Anns canadensis, Linn. S. N. i. p. 198 (1766). 



Bernicla canadensis, Baird, B. of N. Am. p. 764 (1858); March, 

 Proc. Ac. Phil. 1864, p. 70 (Jamaica) ; A. & E. Newton, Ibis, 1859, 

 p. 368 (St. Croix?). 



Anser parvipes, Cass. Pr. Ac. Phil. vi. p. 188 (1852), (Vera 

 Cruz). 



Bernicla canadensis, var. occidentalis, Lawr. Mem. Bost. Soc. 

 N. H. ii. p. 271 (Durango). 



Hab. Jamaica {March) ; Durango, Mexico (Grayson). 



An occasional visitant in Jamaica in winter, its occurrence depend- 

 ing upon the rigour of that season in the north. Messrs. A. & E. 

 Newton think that a flock of wild Geese seen in the Island of St. 

 Croix in 1857 probably belonged to this species. Anser parvipes, 

 from Vera Cruz, is only known to us from Cassin's description, but 

 may probably belong to B. canadensis. Durango is the only other 

 recorded Mexican locality for it. Col. Grayson here met with it.
