EECUEVIEOSTEID^. 



Eecurvirostra americana Gmel. — American Avocet. 



Generally common about the interior lakes. Was also found rather 

 common on the Colorado Eiver near the mouth of an alkaline stream 

 several miles west of the ruins of CaUville. 



Himantopus mexicanus (Miill.) Ord. — Black-necked Stilt. 



This species is found nearly always in the same localities as the Avo- 

 cet, though in less numbers. — [Ridgway.) Several individuals were ob- 

 tained in the Colorado Yalley below the Black Caiion. 



EALLID^. 



Eallus virginianus Linn. — Virginia Eail. 



Two or three specimens of this Eail were seen in May among the 

 sedges bordering a pond near Pyramid Lake. — (Bidgivay.) 



Porzana Carolina (Linn.) Baird. — Sora Eail. 



Common in the northern portion of the State in suitable localities. 

 Also found near the great bend of the Colorado Eiver. 



Porzana noveboracensis (Gmel.) Baird. — Little Yellow Eail. 



" On several occasions and at widely-distant localities we met with a 

 small Eail of a black color, which must have been this species, unless it 

 should prove to be one at present undescribed. It was first seen on the 

 5th of September, 1868, in Euby Valley." — [Ridgway.) 



Fulica americana Gmel. — American Coot. 



Found to be rather common during May and June, when it was ob- 

 served in the Humboldt Valley, in a marsh. 



GEUID^. 



Grus canadensis (Linn.) Temm. — Sandhill Crane. 



This species was found very abundant in the wet grassy meadows in 

 Independence Valley, where they evidently breed. On September 30 

 they were again seen on the Colorado Eiver above the Black Canon, 

 and, when disturbed, rose at once and followed the course of the river 

 southward. 



AN^ATID^. 



Olor huccinator (Eich.) Wagl. — Trumpeter Swan. 



Mr. Eidgway found Swans exceedingly numerous in the -vicinity of 

 Pyramid Lake, but as he obtained no specimens, there is no certainty 

 whether they were the Trumpeter or Whistler (0. americanus).
