Resident. Rather rare in forested areas of the tropical and lower 

 subtropical zones ; reported from Veraguas, and from western 

 Province of Panama (sight record on Cerro Campana) ; recorded 

 mainly from the eastern half of the isthmus from eastern Colon 

 (Cerro Bruja), eastern Panama (Rio Pequeni, Chepo, Cerro 

 Chucanti), Darien (Cerro Sapo, Cerro Mah), and San Bias 

 (Mandinga, Armila, Puerto Obaldia). 



The first specimens of this bird collected by Arce came to Salvin 

 through the dealer Boucard labeled "Veragua," without more definite 

 locality. The sexes are so different that they were named as two 

 distinct species and were so regarded until their identity was estab- 

 lished by Hartert (Nov. Zool., vol. 9, 1902, pp. 600-601). Hellmayr 

 (Proc. Zool. Soc. London, 1911, p. 1207) finally determined that 

 the bird described as cinctus in 1876 was the female and that 

 spodiostethus, named two years later, was based on the male sex. 



The little known of this wood quail relates to the few localities in 

 the eastern half of Panama at which it has been taken. On the 

 Pacific slope I secured a male on April 9, 1949, on a low hill at 

 Zanja Limon on the Rio Mamoni back of Chepo. In February 1950,
