Fiimily FRINGILLID.^.. 



THE FINCHES.' 



Conirostrul, '"ninc-primaried/' aeutiplantar Oscines, with the com- 

 niissuro distinctly and more or less abruptly angulated or deflexed 

 basally, or else with the mandibular rami less than one-fifth as long as 

 gonj\s, the mandibular tomiuni distinctly elevated (often angulated, 

 sometimes toothed) post-medially, thence distinctly (usually abruptly) 

 deflected to the rictus; rictal bristles obvious, usually distinct. 



The above brief and in many respects unsatisfactory diagnosis cov- 

 ers the extreme variations in certain external structural details among 

 a verv large asseiublage of species arbitrarily considered as forming 

 a family Fringillidiv. As here limited the family includes the whole 

 of the Fringillida^ as treated by Dr. Sharpe in the twelfth volume of 

 the Catalogue of the Birds in the British Museum^ (the latest author- 

 ity on the group), only the genus CataDihylyrhynchus being withdrawn,^ 

 with the addition of the genera Pyrrhocoina, Pezopetes^ Buarremon ^^ 

 Arreinon^ Diucopis, Conothraupis^ Oreothraupis (?), Saltator, and 

 ^'' Pity I >(.'<, ^^^ which Dr. Sclater, in the eleventh volume of the same 

 work" (and elsewhere), has placed among the Tanagrida?. 



The group most closely related to the Fringillidre is, of course, that 

 called Tanagridffi, or at least certain mem))ers of the latter, which pos- 

 sibly is, even after the above-mentioned eliminations, too comprehen- 



' Four vernacular names belong exclusively or specially to this family as a whole 

 or in part, and from these I have selected the one which seems to be most appro- 

 priate, although it is difficult to decide between Jivch and sparrow. The fact is that 

 each of these names really has a restricted ai)pli('ability, being commonly applied to 

 minor though more or less arbitrary groups, and based on the comparatively scant 

 European fringilline fauna. They are therefore of still more limited applicability to 

 America form.'<, of which a great majority are very different from those of Europe, 

 and without any distinctive name. The term grosbeak can scarcely be considered in 

 this connection, having been applied indiscriminately to heavy-billed forms with- 

 out regard to their real relationship to one another, not only crass-billed Fringillidae 

 but also Ploceidje having been thus designated.
