basal third, remainder yellow-green, tarsi and toes dull orange. 



Measurements. — Males (2 from Venezuela), wing 99.5-106.5 

 (103.0), tail 38.0-41.8 (39.9), oilmen from base 21.1-23.8 (22.5), tar- 

 sus 25.8 mm. 



Female (1 from Venezuela), wing 100.0, tail 31.1, culmen from base 

 22.6, tarsus 25.4 mm. 



This species is known in Panama from 2 specimens collected by 

 D. C. Booth and W. Martinez in ricefields 6 km west of the airport at 

 Changuinola, Bocas del Toro, on November 10, 1981. The collectors 

 noted that "these birds seem to be common in the tall grass and ditches 

 around the fields. Difficult to observe in the day, but at dusk are readily 

 observed at wet openings and roadsides, frequently in pairs. White- 

 throated Crake [Laterallus albigularis] is found in the same habitat." 

 (Booth and Martinez, notes attached to specimens.) 



N. G. Smith (in lift, to S. D. Ripley) has visited the same area in 

 April and July, when he saw Laterallus albigularis in numbers but did 

 not encounter Neocrex erythrops. He suggests that the latter may be 

 a migrant from South America. 



Only 1 specimen of the 2 from Changuinola survives, and it matches 

 birds of the race olivascens from Venezuela. The previously known 

 range of the species includes Venezuela, Guyana, Suriname, Brazil, 

 Paraguay, and northwestern Argentina.
