10. Trogon. An immature specimen, which, as the young of 

 several other species, agrees with the Trogon strigilatus of Linn. 



11. Centurus Santa Cruzi, Nob. C. albo nigroqtie striatus, 

 capite et corpore suhtus griseo-olivaceis ; vertice cerviceque ru- 

 bris ; fronte et uhdomine aureis ; uropygio albo ; remigibus rec- 

 tricibusque nigris. 



Nearly allied to the Picus CaroUnensis ; but distinct, by its bill 

 being more arcuated, the tail feathers all black, and the golden 

 front and belly ; distinct also from the albifj-ons of Mr. Swainson, 

 which, with a golden belly, has tlie front, the sides of the head, and 

 half of the throat, white : its rump is also thickly banded. 



A much smaller undescribed species in Mr. Swainson's collection 

 (Picus aurifrons) comes still nearer to mine, which, at the request 

 of Colonel Velasquez, I have named after a scientific professor in 

 Mexico. 



12. Icterus Baltimore. Oriolus Baltimore, L. An adult male 

 and a young bird. 



13. Icterus spurius. Oriolus mutatiis, Wilson. Psarocolius 

 castaneus, Wagler. An adult male and a young bird. 



14. Icterus. 



A female bird, closely allied to the Baltimore and the spurius, but 

 different from either : its colours would bring it much closer to the 

 Baltimore, but it wants the black on the throat, whilst aU its under 

 parts are much more vivid than the corresponding portions in any 

 stage of the spurius. Its rump is olive-yellow, the head and the back 

 olive-brown, the white bands on the wings very broad and conspi- 

 cuous. 



15. Icterus Bonariexsis. Psarocolius sericeus, Wagl. PI. Enl. 

 710. Adult male.
