Subspecific characters.- — Male: most nearly like C. p. parvula in 

 general coloration, but decidedly larger, plumbeous area of crown and 

 nape paler and obsolescent, and vinaceous edgings of throat and 

 breast feathers broader. Female very similar in general to the same 

 sex of C. p. pallescens, but decidedly smaller, and usually more brown- 

 ish above. Bill dark throughout in both sexes (in skin). 



Measurements.- — Male (eight specimens): wing, 76-80 (average, 79); 

 tail, 52-58 (55); exposed culmen, 10-12 (10.7); tarsus, 16-17 (16.3). 

 Female (four specimens); wing, 76-77 (76); tail, 50-52 (51.5); exposed 

 culmen, 10-11 (10.6); tarsus, 16-17 (16.3). 



Range. — Guiana and the valley of the Amazon, and around the 

 eastern part of Brazil to Bahia. 



Remarks. — The above diagnosis is based on three males and two 

 females from Diamantina and Santarem, Brazil, all in rather poor 

 condition. Three skins from British Guiana are somewhat paler, 

 verging thus toward C. p. albivitta, although having dark bills, while 

 one from Surinam is quite typical of the present form. Three out of 

 the four females examined are slightly tinged with vinaceous below. 



This form was described by Spix in 1825, under the name Columbina
