* Dr. Sharpe (Cat. Ost. Spec. E. Coll. Surg. p. 294) Las attributed this genus 

 to Dumont (Diet. Sc. Nat. viii. p. 393), who, however, only mentions the word 

 Chenalopex as a nmnen vulgare used by Aristoteles and as a generic term used 

 by Moehring. 



t Following Sclater and Salvin, I have left Anser jubatus, Spix, in the genus 

 Chenalopex, but I have some doubt about its being congeneric with C. agyptiacus.
