1873.] ON AMERICAN LIMICOL.K. 455 



Except in its rather larger size and in the differences above described, 

 this species is very like the preceding. 



2. Macrorhamphus. 



If the American writers are correct, as we believe they are, in distin- 

 guishing two species of this genus, it would appear that both occur 

 in the Neotropical regiou. 



The Guatemalan specimens obtained by Mr. Salvin, and hitherto 

 referred by him to M. griseus *, appear to" belong to the longer-billed 

 and longer-legged species, M. scolopaceus. Mr. Lawrence gives 

 the same species as occurring in Costa Rica (Ann. L. N Y ix 

 p. 141). 



But further south only M. griseus seems to be met with. Mr. 

 Lawrence gives this species in his Panama list (Ann. L. N. Y. vii. 

 p. 479) ; and one of Natterer's Brazilian skins (collected at Praia de 

 Cajutaba, near Para) seems certainly referable to the shorter-legged 

 M. griseus, as Hr. v. Pelzeln has* correctly determined it (Orn. 

 Bras. p. 313). This specimen, we may add, is far advanced in 

 breeding-plumage. 



Mr. Salvin's Guatemalan skins of M. scolopaceus were all obtained 

 in winter, and are either in winter plumage or only just on the 

 change. 



3. Tringa. 



Four of the species of Tringa recognized by the ornithologists of 

 the United States extend far into the Neotropical region. In Salvin 

 and Godman's collection are the following specimens of these spe- 

 cies : — 



1. Tringa maculata, Vieill. ; Cassin, in Baird's B. N. A. p. 720. 

 Of this species we have before us skins from Guatemala (Salvin), 



Panama (M'Cleannan), Peru (Whitely), South Brazil (Rogers). 

 and Chili (Reed). * ' 



2. Tringa bairdi, Coues. 



Of this bird, besides typical northern specimens, we have skins 

 from Mexico, Ecuador (Fraser), Eastern Peru (Bartlett), Western 

 Peru ( Whitely), and Chili (Ley bold) . 



As stated (P. Z. S. 1868, p. 144), we have likewise examined skins 

 of this species obtained by Mr. Hudson near Buenos Ay res ; and we 

 suppose it to be the Tringa dorsalis of Lichtenstein, first described 

 by Burmeister (System. Ueb. iii. p. 374), and very possibly the 

 Chorlito lomo negro of Azara, in which case Tringa melanotus of 

 Vieillot is the first name for it. But both Azara's and Burmeister's 

 measurements are too large for it. 



3. Tringa bonapartii. 



Of the Tringa bonapartii of Schlegel we have before us skins 

 from Panama (M'Cleannan), Ypanema, South Brazil (Natterer),
