Genus HAPLOSPIZA Cabanis. 



(?) Oriturus Bonaparte, Consp. Av., i, July 10, 1850, 469. (Tj^pe, Oriturus 

 mexicanus Bonaparte, = Haploi^piza uniformls Sclater and Salvin ?) 



Haplospiza^ Cabanis, Mas. Hein., i, June, 1851, 147. (Type, Huploqnza imlcolor 

 Cabanis. ) 



Small Fringillida? with elongate-conical compressed bill; wing rather 

 long (about three and a half times as long as tarsus). Init rounded (ninth 

 primary shorter than fourth); tail about three-fourths as long as wing, 

 even or slighth^ double-rounded; adult males uniform gra^^sh. 



Bill elongate-conical, compressed, with straight outlines; exposed 

 culmen about three-fifths as long as tarsus; depth of bill at base less 

 than half the distance from nostril to tip of maxilla, })ut nearl}^ equal 

 to length of gonys; maxillary tomium fainth' concave anteriorly and 

 posteriorly (the latter most decided), faintly convex a little posterior 

 to the middle; mandibular tomium straight to about the middle, then 

 ascending slightly to the apex of the subbasal angle: gonys about twice 

 as long as mandibular rami. Wing rather long (about three and a half 

 times as long as tarsus), rounded (seventh and sixth primaries longest, 

 ninth shorter than fourth); primaries exceeding secondaries by more 

 than length of exposed culmen. Tail alwut three-fourths as long as 

 wing, even or slightly double-rounded, a little more than half hidden 

 by the upper coverts, the rectrices rather pointed Tarsus much 

 longer than commissure, its scutella obvious on inner side, but very 

 indistinct or obsolete on outer side; middle toe with claw about as long 

 as tarsus; lateral claws falling short (?) of base of middle claw; hind 

 claw shorter than its digit. 



Coloration. — Adult male uniform slate-gray; feiuale, olive-green 

 above, paler below. 



The above diagnosis is based on the Brazilian species, 11. nnicolor 

 Cabanis. Whether it will apply to the single Mexican species, H. nni- 

 formis Sclater and Salvin, or not T am unable to state, not having 

 been able to examine a specimen of the latter.^ According to Messrs. 

 Salvin and Godman,^ the latter difiers from the former in being larger, 

 with a larger bill and stronger feet; but whether the bill and feet are 

 larger proportionally is not stated. The female of //. iinifonniK is 

 unknow^n. 



I quite agree with the authors of the Biologia that this genus is 

 nearlv related to Phrygiliis, but have no doubt that it is quite distinct 

 from the latter. 



Range. — Southern Mexico to Brazil.*
