ular rami, the latter without a distinct (if any) lateral groove, but 

 with a raised, differently colored (reddish) laterobasal plate (decid- 

 uous ?); nostril narrowly elliptical (rather narrower posteriorly), 

 parallel with maxillaiy tomium, its anterior end only about one-third 

 the distance from loral feathering to tip of maxilla ; anterior outline 

 of loral feathering forming a nearly straight (faintly convex) ver- 

 tical line, and on the same vertical Ime with the convex malar antia ; 

 mental antia posterior to posterior end of nostril. Wing moderate, 

 moderately concave beneath, much rounded, the longest primaries ex- 

 ceeding distal secondaries by about one-fourth the length of wing, and 

 projecting but little if any beyond tips of longest proximal seconda- 

 ries; second, or second and third, primary (from outside) longest, the 

 outermost about equal to sixth ; alula falling far short of tips of long- 

 est primary coverts. Tail about two-fifths as long as wing, the 

 rectrices moderately broad, moderately J5nn, projecting beyond both 

 upper and lower coverts. Tarsus stout, shorter than culmen or mid- 

 dle toe without claw, the acrotarsium with a continuous single row 

 of broad transverse scutella, the planta tarsi with a lateral series of 

 smaller transverse scutella, those of opposite sides in contact along 

 the sharp posterior ridge; outer toe with claw falling very slightly 

 short of base of middle claw, the inner toe (without claw) reaching 

 to penultimate articulation of middle toe; hallux shorter than basal 

 phalanx of outer toe but longer than that of middle toe ; claws rather 

 short, slightly curved, moderately acute. 



Plumage and coloration. — Plumage full, dense, and rather harsh, 

 that of neck and underparts with barbs separated, producing a some- 

 what hairlike effect, that of the pileum soft and more blended. Up- 

 per parts deep brown and black, streaked with white, that of under- 

 parts spotted and barred with black and white. 



Range. — Tropical South America east of Andes, British Honduras, 

 and Cuba. (Monotj^^ic.)^^

 Pardirallus maculatus maculatus (extralimital)"" 



^Several other South American species have been referred to Pardirallus, but 

 they are so conspicuously different that they constitute the genus Ortygovax 

 Heine, as characterized on p. 42.
