grassy hills near by, and may breed farther south on the mountains. P. anthinus 

 was numerous all summer iu the neighboring marshes, but not away from salt 

 water. 



Passerculus princeps (I, 540). Additional specimens collected at Ipswich, 

 Mass., by Mr. Alaynard, and on Long Island by Mr. Lawrence, confirm the validity 

 of this form, and likewise considerably extend its known range. 



Coturniculus passerinus, var. perpallidus (I, 556). First described in 

 Coues's Key, October, 1872, p. 137. 



Coturniculus lecontei (I, 558). Seven specimens of this interesting species 

 were collected in August, 1873, by Dr. Coues, while attached to the Northern 

 Boundary Survey. Five of them were obtained August 9, at the head- waters of the 

 Souris River, on a boundless prairie. They inhabited the low portions of the 

 prairie, where the grass was tall, recalling to mind the sea-shore marshes inhabited 

 by the Ammodromi of the Atlantic coast. In habits they entirely resembled the 

 seaside Buntings (A. caudacntus and A. maritivius). 



These specimens reveal the fact that Leconte's Bunting is quite as much an 

 Ammodromus as a Coturnicidus, being, in fact, just intermediate between A. cauda- 

 cutus and C. henslowi, agreeing most nearly with the latter in style of coloration, 

 and exactly resembling the former in form, the rectrices being even longer, stiflPer, 

 and more acute. This renders it necessary to unite Ammodromus and Coturniculus 

 into one genus, recognizing them as subgenera, definable chiefly by the different 

 style of coloration of the superior surface in the two groups. The name Ammo- 

 dromus stands as the proper designation of the genus, being of earlier date. 



Several stages of plumage are represented in the series obtained by Dr. Coues ; 

 and, the diagnosis of the species given on p. 552 being taken from a very defective 

 specimen, we give here short descriptions taken from the elegant skins before us. 



Adult male (No. 3,442, Coll. E. C). Ground-color of the head white, tinged with buff 

 on the maxillse, and with ash on the auriculars ; crown with two broad black stripes, 

 separated by a narrow medial one of whitish ; nuchal feathers bright rufous, edged with 

 ashy-w^hite, and shafted with black ; dorsal feathers black, broadly edged exteriorly with 

 white, and interiorly narrowly skirted with rufous. Beneath entirely white, tinged on 

 the throat with buff, and streaked on the sides — from the breast to the flanks — with 

 black. Length, 5.00 ; extent, 7.10 ; Aving, 2.10 ; tail, 2.00; culmen, .42; tarsus, 68. 



Adult female (No. 3,443, E. C). Resembling the male, but, being in less abraded plu- 

 mage, the colors more pronounced. The head is deep buff (just as in Ammodromus cau- 

 dacntus), the auriculars and lores distinctly grayish-white, and the medial stripe of the 

 crown ashy-white, except the anterior third, which is buff. On the lower parts, the whole 

 lower side of the head, the entire breast, sides, flanks, and tibiae, are deep buff", the sides 

 sharply streaked with black. The abdomen, anal region, and crissum are pure white, in 

 marked contrast. Length, 5.00; extent, 7.00; wing, 2.00; tail, 2.10; culmen, .45; 

 tarsus, .70. 



Young (Nos. 3,444, 3,445, and 3,44G, E. C). Ground-color above dull buff, below white; 

 the pattern of the old birds seen in the markings, wdiich, however, are pure black, all red 

 and brown tints being absent, — • except on the wings and tail, which are nearly as in the 

 adult. 



Ammodromus maritimus (I, 5 GO). Mr. Maynard has discovered a very 

 remarkable new local form of this species in Florida, which he has named var. 

 nigrescens, possessing the following characters : —
