LATERALLVS ALBIGULARIS CINEREICEPS (Lawrence) 

 Geay-headed Rail 



Adult (sexes alike), dwrk phase. — Forehead, crown, occiput, lores, 

 malar region, and cheeks deep neutral gray, the median part of occiput 

 washed with bister ; nape, hind neck, and sides of neck and of breast 

 deep hazel to deep chestnut; interscapulars, scapulars, upper wing 

 coverts, and back bister, darkening to clove brown on the lower back, 

 rump, and upper tail coverts; primaries and all but the innermost 

 secondaries dark sepia, the innermost secondaries and the rectrices 

 fuscous-black ; chin and anterior middle part of throat whitish, some- 

 what washed with pale buffy; sides of throat and entire breast and 

 upper abdomen orange-cinnamon darkening laterally to hazel ; lower 

 abdomen, flanks, thighs, and under tail coverts narrowly barred black 

 and white, the dark bars broader than the white ones ; the under tail 

 coverts sometimes slightly tinged with ciimamon; under wing coverts 

 white, indistinctly spotted or mottled with blackish, most nearly pure 

 white along the bend of the wing and on the under primary coverts; 

 iris carmine, bill dull olive blackish with a triangular spot of apple 

 green at the base ; tarsi and toes olive."'^ 



Adult (sexes alike), 'pcde phase. — Similar to the dark phase except 

 that the middle of the throat and breast and abdomen, extending 

 uninterruptedly from the chin to the lower tail coverts, including 

 the thighs, is unmarked white; the sides of the breast paler — flight 

 pinkish cirmamon to pinkish cinnamon; and the light bars on the 

 flanks and sides of abdomen almost as wide as the black ones. The 

 type of leucogastra is a specimen of this kind. 



Juvenal (sexes alike).— Forehead, crown, occiput, and nape bister, 

 each feather indistinctly tipped with clove brown, slightly grayer 

 on the more anterior parts; scapulars, interscapulars, upper wing 

 coverts, and upper back clove brown; lower back, rump, and upper 

 tail coverts fuscous-black; remiges and rectrices as in adult; lores, 

 cheeks, auriculars, and sides of neck smoke gray much mottled with 



" Some specimens have a few small, narrow, black- bordered white bars on the 

 outer, lesser, and middle upper wing coverts ; this seems to be uncorrelated with 

 age, season, or locality. This occurs apparently more frequently in females than 

 in males.
