while correctly adopting T. pectoralis, Say, as a synonym of 

 T. maculata, Vieillotj adds also as a synonym T. Bonapartei, 

 Schlegel, which of course is quite distinct {cf. Compt. Rend. 

 1856, p. 596, and Rev. Zool. 1857, p. 120). Other authors, e. g. 

 Cassin, have designated T. Bairdii as T. Bonapartei. 



" Messrs. Sclater and Salvin observe (P. Z. S. 1868, p. 144) 

 that this species appears to be the ChorlUo lomo negro of Azara ; 

 and if so, Mr. Coues's name will have to give way to Tringa me- 

 lanota, Vieillot [T. dorsalis, Meyen and Licht.). 



" Notwithstanding the confusion which appears to exist with 

 regard to this species, it may be readily recognized by any one 

 who has read the remarks of Mr. Elliott Coues in his Mono- 

 graph of the Tringse of North America (Proc. Acad. Nat. Sci. 

 Philad. 1861) ; Mr. Coues has therein clearly pointed out the di- 

 stinctive characters of this species. 



"Adopting the g&aMS,Actodromas, which was proposed byKaup 

 in 1829, for what he considers ' a well marked and very natural 

 group of Sandpipers,^ he includes therein the five : — A. maculata, 

 Vieillot; A. Bairdii, Coues; A. minutilla, Vieillot; A. Bona- 

 partei, Schlegel; and A. Cooperi, Baird. 



" After pointing out that A. Bairdii is intermediate in size 

 between maculata and minutilla, he gives the characters by which 

 it may be distinguished from the species to which it is most 

 nearly allied in form and colour and with which it has been 

 frequently confounded. These characters may be conveniently 

 stated as follows : — 



"A. Bairdii, Coues. A. Bonapartei, Schleg.
