456 APPENDIX. 



United States as far south as Texas. This Goose must also be included in the list of 

 abnormal migrants to the Bermudas. Macfarlane states (Proc. U. S. Nat, Mus. 

 xiv. p. 423) that breeding grounds of this species are situated on the shores 

 and islands of Esquimaux Lake and Liverpool Bay. 



Allied forms. Chen hyperboreus, an abnormal migrant to the British 

 Islands, and dealt with on pages 314 and 315. The small form of the Snow 

 Goose, and possibly only subspecifically distinct. C. rossi, an inhabitant of 

 Arctic America during summer, migrating south as far as California and Montana 

 in winter. It differs from the two preceding species in being much smaller in 

 size, and in having, as pointed out by Count Salvadori, the bill comparatively 

 weak, and the feathering at the base of the upper mandible, along each side, 

 forming a nearly straight oblique line instead of a very convex line, as in the 

 other three species of Snow Geese. It forms the type of Elliot's genus 

 Exanthemops. C. ccerulescens, an inhabitant of the interior of Arctic America 

 east of the Kocky Mountains, drawing south in winter. It is distinguished by its 

 greyish-brown plumage, becoming bluish-grey on the wing coverts and rump. 



Habits. It is not known that the habits of the Greater Snow Goose differ 

 in any important respect from those of the smaller race. MacfarJane states the 

 belief that the Greater Snow Goose was some days later in arriving at its arctic 

 haunts in spring. These appear to be reached in May and left again in 

 September and October. It is chiefly found during winter on the Atlantic coast, 

 not entering the Mississippi Valley in such numbers as its smaller ally. This 

 Goose during winter frequents inland localities as well as maritime ones. Its 

 food is largely of a vegetable character, grass, roots, ground fruits and berries, 

 varied with insects and mollusks. It is gregarious during winter, and consorts 

 with the smaller race as well as with other allied species. The note, so far as I 

 can ascertain, has never been described. 



Nidification. The information relating to the nidification of this Goose 

 is of a most meagre description, but doubtless the nesting habits differ little 

 from those of the smaller race. The eggs are similar in colour, and I know of 

 no character by which they may be distinguished from those of the preceding 

 form. One brood only is reared in the year. 



Diagnostic characters Chen, with the primaries black and the 

 remainder of the plumage white, with the wing 17 inches or more in length. 

 Length, 30 to 38 inches.
