136 BIRDS OF THE COMMANDER ISLANDS. 



69 (Tfi). Cygnopsis cyguoides (Pall.) 318. 



Dr. Dybowski, iu 1SS2, orally informed me that be had once obtained 

 a head of the present species from Bering Island. This locality is not 

 given, however, in his "Liste des Oiseaux dii Kamtschatlia." 



70 (76). Olor cyguus (Lix.) 149. 



A species of Swan is a regular, though not numerous, winter visitor 

 to the region. Xo Commander Island bird has been positively identi- 

 fied as belonging to this species, but there can be little doubt that it is 

 the one which also occurs in Kamtschatka, while the following species 

 is only an accidental visitor. 



71 (77). Olor columbianus (Ord) 150. 



A single young individual, probably only an accidental straggler, 

 was obtained by me on Bering Island in the beginning of Xovember, 

 1882. , 



72 (78). Anas boschas (Lix.) 152. 



Eesident, breeding numerously in Bering Island; comparatively rare 

 on Copper Island. 



73 (78.i). Chaulelasmus streperus (Lix.) 331. 



Reported by Dybowski as taken on Bering Island ; a straggler only. 



74 (79). Dafila acuta (Lix.) 153. 



Summer visitor ; very numerous on Bering Island, sparingly on Cop- 

 per Island. 



75 (80). Dafila ciC^ca (Lix.) 155. 

 Like the foregoing species.* 



76 (82). Eunetta falcata (Georgi) 156. 



Occasionally straggling to Bering Island during the spring migra- 

 tion. 



77 (84). Mareca penelope (Lix.) 157. 



Visits the islands during the migration season. Two additional 

 specimens, males, were sent by Mr. Grebnitzki (U. S. Xat. Mus., Xos. 

 106618 and 106619). 



78 (85). Mareca americana (Gm.) 158. 



A single straggler was picked up dead among the sand-dunes on Ber- 

 ing Island.t 



* QKerqutdida qiicrqiudula (Lix. ) was uot fouud by me on the isLands. By Dybowski 

 it is stated to have occurred on Bering Island (Bull. Soc. Zool. France, 1884, Extr., p. 

 3), but no particulars are given. The localities as given in the " Liste " referred to, 

 however, are in many instances so incomplete, insufficient, or even quite erroneous, 

 that it can hardly be taken as an authority for occurrences not otherwise expMcitly 

 demonstrated. It is uot unlikely, however, that a few Garganeys may have visited 

 the island during the spring migration of 1883. 



t The first record of Eunetta formosa (Georgi) occurring iu Kamtschatka is by 

 Fischer, who. in the Bulletin Soc. Nat. Moscou, III, 1831, p. 279, described a male 

 from Petropaulski as a new species uuder the name of Anas cucuUata. In the Nouv. 

 M^m. Soc. Nat. Moscou, III, 1834, p. Ill, pi. ix, the specimen was redescribed and 

 figured.
