Show 362 MESSRS. SCLATER AND SALVIN ON [Apr. 4, occasional winter visitant, and with six peculiar species in Antarctic America. 1. BERNICLA CANADENSIS. Anas 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 depending 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. 2. BERNICLA MELANOPTERA. Anser melanopterus, Eyton, Mon. Anat. p. 93 (1838) (Lake Titi-caca); Darwin, Voy. Beagle, iii. p. 134, t. 50 (1841); Schl.
