Ammodromus maritimus, var. nigrescens, Ridgway. 



Char. Above black, nearly uniform, and with a faint brownish cast ; dorsal feathers 

 with their outer edges nairowly grayish-white ; remiges and tail-feathers edged with 

 olive-brown : edge of the wing bright gamboge-yellow ; supra-loral stripe deep yellow to 

 above the middle of the eye ; an obscure supra-auricular stripe of olive-grayish. Lores, 

 auriculars, and cheeks nearly uniform black; lower parts pure white, covered with broad 

 streaks of black, the anal region and middle line of the throat only unstreaked. Wing, 

 2.40; tail, 2.50; culmen, .55; tarsus, .95; middle toe, .55. (1855, Coll. K. E.) 



Specimens of var. maritimus from Fort Macon, North Carolina, are much darker 

 than Connecticut examples. 



Zonotrichia leucophrys, var. gambeli (I, 569). Specimens from the 

 Pacific Coast, which are true gambeli, are uniformly different from Middle Prov 

 ince examples in several important particulars ; the colors are all darker, the 

 ash more sombre, and the dorsal streaks sooty-black instead of chestnut-brown. 

 In everything except the coloration of the head they closely resemble Z. coro- 

 nata. The Middle Province form may be named Zonotrichia leucophrys, var. 

 intermedia, Ridgway. 



Junco (I, 578). For a new synopsis of the genus, see Am. Nat. VII, October, 

 1873, p. 613. 



Junco hyemalis, var. aikeni (I, 584). First described in Am. Nat. VII, 

 October, 1873, p. 615. 



Junco oregonus (I, 584). Dr. Cooper writes that the Oregon Snowbird fre- 

 quents the Sierra Nevada, lat. 39°, up to an elevation of 9,000 feet. He found a 

 nest with three eggs at an elevation of about 7,000 feet, July 28, 1870. 



Foospiza belli (I, 593). A fall specimen from Dr. Cooper, collected at 

 Saticoy, California, October 8, 1872, shows a new plumage of this form, and sub- 

 stantiates the remarkable difference, in every stage of plumage, from var. tievadensis 

 (I, 594). It differs from specimens of the latter in the corresponding dress, in the 

 following particulars : — 



Sub-maxillary bridle deep black, very broad, and reaching to the bill ; pectoral spot con- 

 spicuous, black ; sides strongly washed with ochraceous ; above dark plumbeous instead 

 of light ash; no trace of streaks on the back. Wing, 2.80; tail, 3.00; culmen, .40; tar- 

 sus, .80. (No. 63,652, Mus. S. I.) 



Spizella monticola (II, 3). Collected by Henshaw in Southern Utah, in 

 October, 1872. Probably found, throughout the Middle Province region. 



Spizella socialis (II, 7). Dr. Cooper informs us that the Chipping Sparrow 

 frequents the Sierra Nevada, near latitude 39°, up to 9,000 feet elevation, in sum- 

 mer, and is the only species of Spizella to be seen there at that season. 



Spizella pallida, var. breweri (II, 13). Dr. Cooper met with this species 

 arriving from the South, in small flocks, April, 1873, frequenting bushy grounds 

 ten miles inland. They had the song and habits as described, but were not seen 

 in the low country in summer. 



Melospiza lincolni (II, 31). Dr Cooper writes that in July, 1870, he 

 found this species numerous at and near the summit of the Central Railroad in an
