Very much like C. pretrei from Montevideo, having a red fore- 

 head and the primary-coverts also red, but it differs in the bend of 

 wing and metacarpal edge being green without any red, and in the 

 lores and the region behind the eye also without any red, of which 

 there is always a trace even in the young C. pretrei. {Cuba, us.)
