coming paper on Spix types. Although D'Orbigny's so-called female belongs to 

 another subspecies, his diagnosis is clearly referable to the dark-backed form, which 

 accordingly ought to be called S. coendescens azarac, D'Orb. 

 The distribution of the two subspecies is as follows : 



a. Saltator coerulescens coerulescens Vieill. 



Saltator coerulescens Vieillot, Nutiv. Diet. xiv. (1817), p. 105 (ex Azava No. 81 : Paraguay). 

 Tanugra siiperciliaris Spix, Av. Bras. ii. (1825), p. 44, tab. Ivii. ('• in campis fl. St. Frauoisci prope 



pagum Joaseiro" Bahia, Brazil). 

 Saltator azarae (nee D'Orbigny), Pelzein, Zur Orit. Bras. iii. (1869) p. 219 (Mattogrosso). 

 S. coerulescens Salvador!, Boll. Mns, Torino xv. No. 378 (1900) p. 4 (Mattogrosso). 

 S. Azarae D'Orbigny, Voi/age, Oiseaux, p. 287 (part. : female ; Santa Cruz de la Sierra, Bolivia). 



Hab. Campos region of the interior of Brazil from Joazeiro on the Rio 

 Francisco, Bahia to Mattogrosso (Onyaba, Villa Bella, San Vicente, Oarandasinho, 

 Urucum), and thence to Santa Cruz de la Sierra in East Bolivia ; southwards 

 through Paraguay (Bohls coll. — in Mus. Tring et Berlepsch) to Corrientes, Argentina 

 (D'Orbigny coll. — specim. in Mus. Paris). 



b. Saltator coerulescens azarae D'Orb. 



Saltator Azarae D'Orbigny, Voyage, Oiseaux, p. 287 (part : descr. (J ; Mojos, Bolivia). 

 S. nuperciliaris (nee Spix) Sclater, Cat. Birds xi. p. 2'Jl (part. : Ecuador and Peru). 



Hab. N.E. Bolivia (Moxos); Upper Amazonia: Central and Eastern Peru, 

 East Ecuador, Bogota coll. ; N.W. Brazil : Rio Jurna (Garbe coll. — Mus. 

 Berlepsch). 



A third closely allied form occurs on the Lower Amazons : 



c. Saltator coerulescens mtttiis Scl. 



Saltator miitus Sclater, P. Z. S. 18.'i6, p. 72 ^Para]. 



S. superciliaris (neo Spix) Sclater, Cat, Birds xi. p. 291 [part. : Mexiaua]. 



Very much like S. c. azarae, but with the anal region and the crissum 

 considerably paler, ochraceous buff (instead of deep ochraceous). 



Hab. Vicinity of Para : Mexiaua Island (Wallace), Oamolins (Steere coll. — 

 Mus. Tring). 



11. Saltator albicollis Vieill. = S. guadeloupensis Lafr. 



Saltator albicollis Vieillot, Xonr. Diet. xiv. (1817) p. 107 ['' Cayenne " — errore !]. 



Specimen in Mus. Paris, labelled: " Habia albicol, Saltator albicollis, Vieill. 

 (T.), de Cayenne, donn^ par M. Moussier." On the bottom of the perch : " donn(5 

 par M. Moussier, 1808. Salt, albicollis Vieill. type. Type do la description de 

 M. Ch. Bonaparte." Wing 94 ; tail 90; bill l8i mm. 



Mr. Sclater* says : " I have examined tlie type of S. albicollis of Vieillot at 

 Paris, and believe it to be an immature bird of this species " (i.e. S. striatipictus 

 Lafr.). 



This statement is quite erroneous, and, I su])pose, the examination must have 

 been a hasty one, for otherwise Mr. Sclater would not have i'ailed to recognise 

 the true afHnities of the bird. Vieillot's type is by no means immature, but an 

 adult bird in very worn plumage, and belongs to the species inhabiting the islands 

 of Guadeloupe, Santa Lucia, etc. It agrees with specimens from the latter island in 



• Cat. Birds, xi. p. 295.
