Part I. containing the genera Pitylus, Orchesticus, Diucopis, Sa.l- 

 tator, Psittospiza, Lamprospiza , Cissopis, Oreothi-aupis, Arremon, 

 Phcenicophilus, Buarremon and Chlorospingus . 



Genus I. Pitylus. 



Pitylus, Cuv. Regn. An. 1829, ii. p. 413. 

 Cissurus, Reich. Av. Syst. Nat. pi. 77. 

 Periporphyrus, Reich. 1. c. 

 Caryothraustes, Reich. 1. c. 



Rostrum maxinium, breve, altum, latum, quasi coccothraustinttm; 



mandibulcB superioris marginibus fortiter sinuatis et mandibulam 



inferiorem tegentibus ; culmine multum iticurvo : alce modiccB, 



remigibus tertia, quarta et quinta longissimis : cauda plūs minusve 



elongata, pleru7nque rotundata : tarsi robusti. 



The birds of this genus are the most finch-like of the Tanagers, 



and I have some doubts vvliether they are not as closely allied to 



Guiracu, Hedymeles, and other Coccothraustine forms, as to the pre- 



sent group. We want more information as to their habits and in- 



ternal structure before this poiut can be satisfactorily settled.
