50 Recent Literature. 



Dr. Cones gives us the results of his field-work during the seasons of 1873 

 and 1874 in Northern Dakota and Montana, while acting as naturalist and 

 surgeon to the United States Northern Boundary Commission. The ob- 

 Bervations relate mainly to the country immediately bordering the forty- 

 ninth parallel, which was surveyed from Pembina, on the Red River, to 

 the Rocky Mountains, or for a distance of about eight hundred and fifty 

 miles. Dr. Coucs, in Ids preliminary remarks, divides the country trav- 

 ersed into three regions, which he terms respectively the " Red River 

 Region," the "Missouri Region," and the "Rocky Mountain Region." 

 The physical and zoological characteristics of these regions are briefly de- 

 tailed, to which is added a tabular enumeration of some of the more con- 

 spicuous birds of the three regions. Then follows a copiously annotated 

 list of all the species observed, with lists of the specimens obtained, accom- 

 panied frequently with measurements. The Missouri Skylark (Neocorys 

 spraguei) very naturally comes in for an extended notice, as do also two* 

 species of Longspur (Plactrophancs ornalus and P. maccoicni) and Baird's 

 Bunting, relating especially, however, to their respective areas of distribu- 

 tion. At page G48 we notice interesting general remarks on the breeding 

 range of our Geese and Ducks, and concerning the great numbers of indi- 

 viduals that sometimes assemble about the prairie sloughs and mountain 

 pools. It is also noted that partly grown young of the Canvas-back Duck 

 were secured at Turtle Mountain, while young of the Harlequin and Rocky 

 Mountain Golden-eye (Bucephala islandicu) were obtained at Chief Moun- 

 tain Lake. Respecting this latter species Dr. Coues says: "This is, I 

 believe, the first recorded instance of the occurrence of this species dur- 

 ing the breeding-season in the United States." Hence it may be worth 

 while to here record that eggs of this species, in the Museum of Com- 

 parative Zoology, were obtained in Middle Park, Colorado, by Mr. Edwin 

 Carter, June 3, 1877. The paper concludes with a bibliographical ap- 

 pendix of nearly three pages, in which are entered the titles of nearly 

 forty works anil papers relating to the ornithology of portions of country 

 adjacent to the forty-ninth parallel. — J. A. A. 



Merrill's Notes ox the Ornithology of Southern Texas. — 



Attention bus already been called through the pages of the Bulletin to Mr. 



Sennett'a " Notes on the Ornithology of the Lower Rio Grande of Texas." 



That interesting locality now receives a still more complete overhauling at 

 the hands of Dr. J. C. Merrill, U. S. A.,* who has been stationed for sev- 

 eral years past at Brownsville, Texas. Although to some degree antici- 

 pated by Mr. Sennett'a list, as well as by various previously published 

 announcements on the part of the author himself, this paper comes to us
