Goldfinches of this species were henceforth noted in small numbers 

 as follows : opposite Cibola, ten miles below Cibola, twenty miles north 

 of Picacho, eight miles east of Picacho (full grown young taken), four 

 miles below Potholes and near Pilot Knob (family of young) . Twenty- 

 five specimens were taken, nos. 13091-13115. These are identical with 

 the form inhabiting the Pacific slope of California. Of the sixteen 

 males in the series, not one is of the arizonae or mexicanus type of 

 coloration, that is, with unusual extensions of black in the plumage. 



Astragalinus lawrencei (Cassin) 

 Lawrence Goldfinch 

 Observed only on the California side at Riverside Mountain, March 

 17 : a flock of eight was discovered in the upper branches of a dead 

 mesquite on the verge of the river bank, singing and calling in char- 

 acteristic fashion. Two were procured, nos. 13089-13090. 



A siugle specimen (no. 4164) is in the Museum, taken by J. G. 

 Cooper at Fort Mohave January 28, 1861. The species is probably 

 a winter visitant to the Colorado Valley, though not in abundance. 



Passer domesticus Linnaeus 

 English Sparrow 

 Several dozen were apparently well established in the station park 

 and about the railroad yards of Needles. They had their retreats in 

 the palms and eucalyptus by the station. One lone individual was 

 seen in some willows on the Arizona side half a mile above the railroad 

 station at Mellen, February 24. 



Pooecetes gramineus confinis Baird 



Western Vesper Sparrow 



Met with in but two places : on the California side, in Chemehuevis 

 Valley, where a specimen, no. 13124. was secured March 10; and on the 

 Arizona side, above Bill Williams River, March 12 and 13, where 

 three specimens were taken, nos. 13125-13127. A few others were 

 seen in the latter locality, where they were all found in a growth of 

 tall coarse grass paralleling the mesquite belt. 



There is in the Museum a skin (no. 4155) taken by J. G. Cooper 

 at Fort Mohave, March 6, 1861. This sparrow probably occurs in 

 the region throughout the winter.
