Of the genus Capito, besides the C. cayanensis and C. peruvianus 

 and the intermediate C. amazoninus, there is a very beautiful fourth 

 species, C. aurovirens (Le Vaill. Prom. Suppl. pi. E., Bucco auro- 

 virens, Cuv.) . This bird was met with at Sarayacu on the Ucayali 

 by MM. Castlenau and Deville during their voyage, and there are 

 specimens in the Paris Museum from their collection. Mr. Gould 

 possesses specimens obtained by Hauxwell on the šame river. 



The third and only remaining American genus of the family is 

 Tetragonops, a very peculiar form from the Quitian Andes, de- 

 scribed by Sir William Jardine in the Edinb. N. Phil. Journ. 1855, 

 n. 8. ii. p. 404.

 genera, and even great families of birds, formerly existed on the sur- 

 face of the globė, of which no living representatives now remain, but
