DESCRIPTION OF A NEW RICE GRACKLE. 
BY OUTRAM BANGS. 
WHEN I was in Washington this spring, Mr. Robert Ridgway 
and I got together and compared a large series of rice grackles; 
when it at once became apparent that the Colombian bird needs a 
name, differing much from either true Cassidix oryzivora (Gml.) 
or C. oryzivora mexicana (Lesson). 
Cassidix oryzivora oryzivora inhabits Guiana, Trinidad, and the 
Amazon Valley, including central Ecuador, and probably also 
Venezuela. The new form occurs throughout Colombia, north to 
the Isthmus of Panama. The Panama specimens are not typical, 
but incline toward C. oryzivora mexicana of southern Mexico. 
The Colombian form may be known by the following diagnosis. 
Cassidix oryzivora violea’ subsp. nov. 
Type, from La Concepcion, Sierra Nevada de Santa Marta, 3000 feet alti- 
tude, Colombia, adult ¢, no. 5855, coll. of E. A. and O. Bangs, collected 
Feb. 12, 1899, by W. W. Brown, Jr. 
Subspecific characters.— Similar to Cassidix oryzivora oryzivora, but larger, 
and the adult male with the plumage glossed with violet instead of bronzy (it 
1 Violeus — of a violet color.
