"Very full: includes some critical commentary on geographical distribution in general, 

 and on relationships of certain disputed species. Iowa, 108 spp. ; Illinois, a, Ogle Co., 84 spp. ; 

 b, Cook Co., 94 spp., with monographic account of certain Turdidae; Indiana, 72; the anno- 

 tations in each case chiefly field-notes. 



"'Range in the breeding-season must form the basis for defining the limits of different 

 ornithological districts. . . .Among migrants of the same species the examples which arrive 

 in the spring the earliest are bigger and more brightly tinted than those which come later, 

 and, conversely, on their return the examples last seen are bigger than the summer specimens.' 

 Hence it would appear that the largest individuals are those which go furthest north in 

 summer, and, he also adds, are those which live further north in winter. Some characteristics 

 of the ornithological provinces of North America are next briefly mentioned; and then 

 follow the lists of species observed, as stated in the title. In Iowa about 108 or 110 species 

 were seen, of which at least 100 breed in the State. For Illinois two lists are given, one of 

 84 species in Ogle County, the other of 94 species in Cook County. At Richmond 72 

 species were observed by himself and Dr. Haymond. Some critical notes on supposed 

 species (Turdidae, Laridae) are added in the course of the paper." — Coues, I. c, p. 676,

"315 species (cf. footnote, p. 647) in Massachusetts. The paper is supplementary to the 

 author's Massachusetts catalogue published five years before in Proc. Essex Inst.; it contains 

 critical comments on the rarer or less generally known species, and discusses the cases of some 

 doubtful ones. The supposed Buteo 'cooperi' proved to be lineatus." — {Coues, I. c, p. 682.)
