Its range, 'so far as known at present, extends from Patzcuaro, 

 Michoacan, north to within fifty miles of the Arizona border in 

 northern Chihuahua. This covers parts of the Territory of Tepic 

 and of the States of Michoacan, Jalisco, Zacatecas, Durango and 

 Chihuahua.

 the birds of North and Middle America upon which the author 

 has been engaged for the past four years, the completion of which 

 must necessarily be long delayed. Only brief diagnoses are here 

 given, detailed descriptions being reserved for the larger work 

 referred to. 



Several of the genera included here have usually been placed 

 with the so-called Tanagridae ; but I am fully convinced, after 

 long and careful study, that if it should prove practicable to 

 retain a separate family equivalent, in part, to the usually accepted 

 Tanagrida;, it can only be done by materially restricting its limits. 

 At any rate, it is quite certain that the genera Pitylus (restricted 

 to P. grossjis and F.fuliginosus) , Pezopetes, Buarremon, Arremon, 

 Lysurus, and Pselliophorus are true Fringillids, and very closely 

 related to such unquestionably fringilline genera as Cardinalis, 

 Pipilo, Pyrgisoma, Atlapetes, Arremoiiops, etc. Some doubt is 

 attached to such genera as Stelgidostomus, Heterospingus, Mitro- 

 spingus, Rhodothraupis, and Hemithraupis, which certainly are
