32 EXPLORATIONS AND SURVEYS WEST OF JOOTH MERIDIAN. 



Chaulelasmus streperus, (L.) Gadwall. 



Few only seen late in November at Provo. 

 Marcea americana, (Gin.) Baldpate. 



Numerous. 

 Fuligula mania, (L.) Greater Blackhead. 



Rather common. 



Fuligula collaris, (Donov.) Eing-necked Duck. 



Single young female taken at Rush Lake in September. Probably 

 migrates south comparatively early in the season. 



Fuligula ferina^ (L.), var. americana Eyton. Redhead. 



But few seen. 

 Bucephala clangula, (L.) Golden Eye. 



Numerous in Provo River. 

 Bucepliala islandica, (Gm.) Barrow's Golden Eye. 



A pair of these ducks were taken in the Provo River December 1. 

 This is the first instance of the discovery of this bird so far inland, and 

 to the southward. Believed not to be uncommon, as gunners distin- 

 guish it from the preceding by its large size. 



Bucepliala albeola, (L.) Butter-Ball. 



Common. 

 Erismatura rubida, (Wils.) Ruddy Duck. 



Rather uncommon ; taken at Provo in November. 



Fergus serrator, L. Red-breasted Merganser. 



Very common. 

 Fergus cucullatus, L. Hooded Merganser. 



Rather common. 



NOTE. The observations upon the foregoing species were made in 

 Spring and Snake Valleys, Nevada, and Rush Lake and Utah Lake, 

 Utah ; but as more time was spent at Utah Lake than at the other points, 

 it may be assumed that the notes apply more particularly to this locality.
