Genus RHODOTHRAU PIS Ridgway. 



Rh<i(hillirauph Ridgway, Auk, xv, no. 3, July (pul). May 14), 1898, 226. (Type, 

 Fr'mgUla cclicno Lichtenstcin. ) 



Siiiiihir to ('/(/-//of /(/•(( uHes Ijrit tail much longer (nearly aw long as 

 wing) and decidedl}' rounded; ninth primaiy not longer than second, 

 instead of longer than third; tarsus decidedly longer than middle toe 

 with claw.' Sexes diii'erent in color, though similar in pattern, the 

 adult male being dull carmine red below and across hindneck, other- 

 wise, including head (all round) and chest, black; adult female and 

 immature male with head and chest black, otherwise plain olive-green, 

 more 3'ellowish on under parts and hindneck. 



Range. — Eastern Mexico. (Monot3'pic.) s 



\Vhil(> bearing a strong superiicial resemblance in coloration to Peri- 

 porj)hyrui<.,^ this genus is exceedingly' distinct in structure, in which 

 respect it is much more nearly related to Caryothraiistes. The bill is 

 less ditierent in form from that of C. vi/ndis or O. j^oliogaster than 

 these are from one another, but the nostril appears to be more rounded 

 than in either, with less of an overhanging membrane. Rhodothraupis 

 agrees with Pevlporphyrus in lengthened and distinctly rounded tail, 

 and, to a degree, in the pattern of coloration, but the bill is exceed- 

 ingly different in form. 



RHODOTHRAUPIS CEL^NO (Lichtenstcin). 

 CRIMSON-COLLARED GROSBEAK. 



Adult male. — Head, foreneck, chest, and upper parts (except hind- 

 neck) plain black; hindneck and under parts of body (posterior to 

 chest) dull red, darker (nearly burnt carmine) on hindneck, lighter and 

 brighter (sometimes almost poppy red) on under parts, where the 

 feathers are more or less black centrally;' under tail-coverts dusky, 

 margined (usually broadly) with light red or pink; axillars, under

 reduced to a narrow margin, the flanks sometimes uniform black. In other speci-
