Sharpe, however, recognizes Columbiana and refers Santa Marta specimens 

 to flaveola and since the specimens hgted below agree with a large series from 

 Santa Marta, I accept Sharpe's determination. 



Turbaco, 2; La Playa, 2; Calamar, 3; Boca de Chimi, 1. 



(3850) Sicalis arvensis minor Cab. 

 Syealis minor Cab., in Schomb. Reis. Guian, III, 1848, p. 679 (British Guiana). 



One of the most abundant birds on the Bogota Savanna where we saw 

 it in large flocks; occurs also in the Magdalena Valley but is rare in the 

 Cauca Valley. 



Our specimens are more richly colored above than Lima specimens of 

 luteiventris, and lack the white or whitish apical area on the inner vane of the 

 outer rectrix. I have, however, no specimens of true minor for comparison. 



Cali, 1; Chicoral, 1; Bogota, 4; Subia, 2; Puente Andalucia, 1; El 

 .Carmen, 1; La Mar, 2.

Ammodramus savannarum caucce Chapm., Bull. Am. Mus. Nat. Hist., XXXI, 

 1912, p. 161 (CaU, Col.). 



Char, subsp. — Similar toA.s. australis but darker, black central areas to feathers 

 larger, chestnut areas smaller and darker, edgings to feathers grayer, less buffy. 



Known only from three specimens taken at Cali. In view of the some- 

 what restricted character of the avifauna of the Tropical Zone of the Cauca 

 Valley it is somewhat surprising to find there two species of Sparrows of 

 sedentary habits. The present species appears not to have been recorded 

 elsewhere on the South American mainland, though a form of it {A. s. cari- 

 hwus Hart.) has been described from the islands of Cura9ao and Bonaire.
