Genus FORMICARIUS Boddaert 



Formicarius moniliger Sclater 



Proc. Zool. Soc. London 24: 294, January 26, 1857. 

 =Formicarius analis moniliger Sclater. See Peters, Checklist of birds 



of the world 7: 240, 1951. 

 22367. Adult male. Mexico. Entered into the museum register on 



October 26, 1861. Received from the Maison Verreaux. 

 This specimen bears the conventional green label of the Maison Verreaux, 

 from which all essential data are missing, but on it appears the word 

 "type." The fact that Sclater referred to both males and females indicates 

 that he examined more than one skin, and No. 22367 could easily be one 

 of the cotypes; its true status, however, must probably remain forever 

 doubtful. The only unquestionable cotype is perhaps the male in the 

 British Museum {ex Sclater Collection), taken by Salle at Cordoba.
