Lophortyx Bonaparte, Geogr. and Comp. List, 1838, 42. (Tj'pe, as designated by

 Lophortix (emendation) Bonaparte, Compt. Rend., xxxviii, 1854, 663. 

 Callipepla Reichenow, Die Vogel, i, 1913, 317, part. 



Medium-sized Odontophorinae (wing about 108-120 mm.) with tail 

 more than three-fourths as long as wing, 12 rectrices, crest long, club- 

 shaped, consisting of several plumes with webs convolute, the uppermost 

 plume thus enclosing those beneath; chest plain grayish (not squamated), 

 and sexes conspicuously different in coloration. 



Bill relatively small, the chord of culmen (from extreme base) less 

 than half as long as tarsus, its depth at base not greater than distance 

 from anterior end of nasal fossa to tip of maxilla, and about equal to its 

 width at rictus. Outermost primary shorter than eighth (shorter than 

 ninth in L. douglasii), the fourth, fifth, and sixth or fourth (in L. doiig- 

 lasii) longest. Tail three-fourths as long as wing or more, graduated, the 

 graduation equal to two-thirds the length of tarsus or more ; rectrices 

 (12) rather broad, slightly tapering terminally (except in L. douglasii), 

 with rounded tips. Tarsus decidedly less than one-third as long as wing 

 (about one-fourth as long in L. douglasii), shorter than middle toe with 

 claw, the planta tarsi covered mostly with rather small hexagonal scutella 

 but those near posterior edge of outer side larger, more transverse, and 

 tending to form a continuous linear series. 



Plum-age and coloration. — Feathers of forehead narrow, erectile, some- 

 what bristlelike ; springing from center of crown a conspicuous elongated 

 club-shaped crest comprised of several plumes with conduplicate webs 

 narrower basally, broader terminally (in L. calijornica and L. gambelii) 

 or in middle portion (in L. douglasii) , the uppermost plume folding over 

 or enclosing anteriorly and laterally the other plumes. Scapulars, tertials, 

 rump, etc., unspotted, but inner webs of tertials edged with buff or white ; 

 chest plain gray. Sexes conspicuously different in coloration.
