BIRDS. 
83. NETTION CABOLINENSIS, Baird, (p. 777.)—Green-winged Teal. 
9722. $ , 9 . Bio Bita, Laguna, New Mexico, November 12, 1854. (3.)—9723. 9 . 
Ditto. Kennerly and Mollhausen. 
This duck was probably more abundant than any species that we met with. Besides finding 
great numbers along the Bio Grande, we scarcely ever failed to see it during our westward 
journey, wherever we found running water. 
84. QUEBQUEDULA CYANOPTEBA, Baird, (p. 780.)—Bed-breasted Teal. 
9750. Mohave river, March 11, 1854.—9740. $ . Camp 123, February 16, 1854. (166.) 
Kennerly & Mollhausen. 
We saw this bird frequently on Bill Williams’ Fork, Great Colorado and Mohave rivers. 
The male, when in full plumage, is one of the most beautiful of all the ducks ; but they seemed 
to be remarkably scarce in comparison with the number of females. 
85. CHAULELASMUS STBEPEBUS, Gray, (p. 782.)—Gadwall. 
9796. $ . San Francisco, California, March, 1854. 
86 . AIX SPONSA, Boie, (p. 785.)—Summer Duck. 
9776. San Francisco, California, $ , February, 1854. Kennerly and Mollhausen. 
This beautiful duck we did not see before reaching San Francisco, in the vicinity of which 
place we found it very abundant. 
87. FULIX AFFINIS, Baird, (p. 792.)—Little Black Head. 
We found this duck very common in the vicinity of San Francisco, but did not observe it 
before reaching that place. 
88 . BUCEPHALA ALBEOLA, Baird, (p. 797.)—Butter Ball. 
9813. Bill Williams’ Fork, New Mexico, February, 1854. (89.) 
This expert little diver we saw occasionally in small flocks, in the month of February, along 
Bill Williams’ Fork and the Great Colorado river.
