CHARACTERS OF HARPORHYNCHUS CINEREUS 69 



nnHE history of this bird is short, if not also in keeping 

 -*- with the rest of the familiar quotation. That it should 

 have been overlooked by all the earlier explorers in Arizona 

 is probably a result of its extremely local distribution ; in 

 fact, it is only known to inhabit a very restricted area in South- 

 ern Arizona, in the vicinity of Tucson. It was discovered in 

 1872 by the zealous collector whose name it bears in recogni- 

 tion of the services he has rendered in developing the orni- 

 thology of the Southwest. In the spring of 1873, while at Fort 

 Eandall, Dakota, I received specimens from Lieutenant Bea- 



rather purer aucl darker brown, the former crossed with two white bars 

 formed by the tips of the coverts, the latter tipped with white. Below, dull 

 white, often tinged with rusty, especially behind, and thickly marked with 

 small, sharp, triangular spots of dark brown or blackish. These spots are 

 all perfectly distinct, and cover the lower parts excepting the throat, lower 

 belly, and crissum. Becoming smaller anteriorly, they run up each side of 

 the throat in a maxillary series bounding the immaculate area. The sides of 

 the head are finely speckled, and the auriculars streaked. The bill is black, 

 lightening at the base below, and little if any longer than that of R. rtifus, 

 though decidedly curved. Length of ^ about 10 inches; wing, 4 ; tail, 4^; 

 bill, 1^; tarsus, li; middle toe and claw, li. $ averaging rather smaller.

Young: In a uewly-iiedged specimen, the upper parts are strongly tinged 

 with rusty-brown, and this color also edges the wings and tips the tail. 



The striking resemblance of this species to the Mountain Mockingbird, 

 {Oroscoptes viontanus) has been noted. The species is immediately distin- 

 guished from any others of the United States by the sliariiness of the spot- 

 ting underneath, which equals that of H. rufus itself, the small and strictly 

 triangular character of the syjots, together with the grayish-brown of the 

 upper parts, and inferior dimensions. The bill is shaped much as in curvi- 

 rostris and Jja?/Herj. if. ocellaiua of Mexico is even more boldly marked 

 below, but the spots are large, rounded, and black.
