142. CuRVIROSTRA AMERICANA WilsOtl. 



If, as is probably the case, the Loxia mexicana of Strickland is rightly to be 

 referred to C. americana, then this species, being found breeding upon the Table 

 Lands of Mexico, and so general'y distributed throughout North America, must 

 be added to the Arizona list. It is doubtless to be found at times at Fort Whipple. 



Chrysomitris trislis, Aegiolhus linarius, and, perhaps, Curvirostra leucoptera and 

 Pinicola canadensis, though not to my knowledge hitherto detected in Arizona, 

 will most probably be discovered in winter towards the northern boundary of 

 the Territory. 



143. Pi.ectrophanes MF.i,AxoMus Baird. 



Resident? Rare. A single specimen taken Oct. 17, 1864, on open, grassy 

 plains, is rtferrible to this species. 



Some interesting peculiarities of the r >nge of habitat of this species assist 

 the characters presented by the bird in separating it from P. ornatus. It is 

 known to breed on the Table Lands of Mexico. 



(144.) Pi.ectrophanes Maccownii Lawrence. 



Extends from the vast arid plains of New Mexico into those of Southern 

 Arizona. {Dr. Ileermann.) 



145. Calamospiza bicolor (Towns.) Bon. 



" Abundant near the Pima Villages, A. T.," Dr. A. L. ITeermann. This 

 gentleman al-o s>iys that he found it in the Mesilla Valley near Fort Fillmore. 

 In crossing the Great Plains I found it abundant as far as the Raton Moun- 

 tains, westward of which I have never seen it. In the north its westward 

 range seems limited, but it extends al^ng the Mexican border, and across the 

 Southern Rocky Mountains and Valley of the Lower Colorado, and is found 

 also at Cape St. Lucas. It is not recorded from the coast region of Upper 

 California. 



146. Chondestes grammacus (Say.) Bon. 



Chiefly spring and autumn migrant, being very numerous at those seasons. 

 Many breed, and a few remain all winter. Extends southward to Mexico. 

 ' Not detected in the Colorado Valley even in winter." (Cooper.) 



147. Passercdlcs alaudinus Bonap. 



Abundant. Summer resident. My numerous specimens are referrible to 

 this supposed species, ditfering in some slight degree from the average of east- 

 ern birds in the grayish rather than decidedly yellow superciliary streak, and 

 the general paleness of the colors. The bill is perhaps a little slenderer and 

 more elongated. The differences which separate it from savanna appear to me 

 no greater than are to be found when large series of the latter are compared 

 with each other. 



For some additional data upon the relationships of the North American Pas- 

 xercitli, see the London Ibis for 1866. 



148. Pooecetes graminecs (Gm ) Baird. 



Very abundant. Summer resident. Winters in the Colorado Valley. Arrives 

 last week in March. Remains till November. I can detect no differences be- 

 tween eastern and western birds. 



149. Coturniculus PASSERiNUS (Wils.) Bon. 



Rare. Not observed at Whipple. Bill Williams' River, Kennerly. 



150. Zonotrichia Gambeli (Nutt.) Gambel. 



Abundant. Resident. First noticed Sept. 15, and at once becoming ex- 

 c<edingly numerous, they continued so until January ; after which only a few 

 stragglers were seen until the latter part of April, when they again became 

 common. By far the greater part go further north to breed. In general hab- 

 its this species seems to resemble albicollis rather than ;he more closely allied 

 . leucophys.
