Genus HAPLOSPIZA Cataanis. 



(?) OrUurus Bonaparte, Consp. Av., i, July 10, 1850, 469. (Type, Orilurm 

 mexicanus Honaparte, = Haplospiza uniformis Sclater and Salvin ?) 



Jfaplospiza^ Cabanis, Mus. Hein., i, June, 1851, 147. (Type, Haplogpiza unicolor 

 Cabanis. ) 



Small Fringillidae with elongate-oonical compressed bill; wing rather 

 long (ahout three and a half times as long as tarsus), but rounded (ninth 

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

 even or slightly double-rounded; adult males uniform grayish. 



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

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

 than half the distance from nostril to tip of maxilla, but nearly equal 

 to length of gonys; maxillarj- tomium faintlj- concave anteriorly and 

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

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

 ascending slightl}^ to the apex of the subbasal angle; gonj's 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 about three-fourths as long as 

 wing, even or slightl}' 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; female, oliA"e-green 

 above, paler below. 



The above diagnosis is based on the Brazilian species, JI. vnivolor 

 Cabanis. Whether it will applj"- to the single Mexican species, II. uni- 

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

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

 Salvin and Godman,^ the latter differs 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 //. tanforinia is 

 unknown. 



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

 nearl}' related to Phrygilics, but have no doubt that it is quite distinct 

 from the latter. 



Range. — Southern Mexico to Brazil.'
