Evidently the Guatemalan representative of the Mexican J. cine- 

 reus.

 reliquorum pogoniis externis in parte basali Jlavis, in parte ter- 

 minali nigris flavo marginatis, pogoniis internis omnium fiavo

The two specimens from which the above description is taken differ 

 considerably in coloration from one another, one being in old and 

 somewhat worn plumage, the other more freshly moulted and brighter 

 olivaceous. They are both males ; and the former, from the greater 

 amount of yellow in the spots on the wings, I consider as the older 

 bird. This variation in the extent of yellow on the wings and tail 

 is seen in the allied species C. notata, the female having less than 

 the male. At first sight the present species might be taken for the 

 young of C. notata (in which the sexes are almost alike) ; but the 

 longer wings and more deeply forked tail point to its distinctness. 



The two specimens were shot by Mr. R. Owen and myself amongst 

 a patch of thistles near Quezaltenango, iu August last (1862).
