3. MiMUS CALANDRIA (Lafr. et d'Orb.) ; Burm. /. c. p. 475. 



"We are now convinced that Mimus modulator, Gould, is identical 

 with this species. Sclater's Bolivian M. caJandria (P. Z. S. 1859, 

 p. 343) seems to differ principally in its smaller dimensions, and 

 is perhaps hardly distinct. 



4. POLIOPTILA DUMICOLA(Vieill.). 



CuUcivora dumicola, Burm. /. c. p. 4/3. 

 "Resident." 



5. Anthus correndera (Vieill.). 

 A. rufus, Burm. /. c. p. 4/4. 



" Resident." 



6. Geothlypis velata (Vieill.). 



Two specimens of this species, agreeing with Brazilian skins. Not 

 mentioned by Burmeister. " Summer visitor." 



7. Progne tapera (Linn.). 



Cohjte tapera, Burm. I. c. p. 477. 



H.fusca, Vieill. ex Azara, No. 301. 



PhcBoprogne fusca, Baird, Rev. A. B. p. 285. 



Several examples of this species, agreeing with specimens so named 

 in Sclater's collection. We do not know Baird's P. tapera as dis- 

 tinguished from h.\% P.fusca. 



8. HiRUNDO leucorrhoa (Vieill.). 



Cotyle leucorrJuea, Burm. I. c. p. 478. 



Several examples of this distinct species. H. allilinea of Law- 

 rence is rightly associated by Baird (Rev. A. B. p. 297) with this 

 species, but is readily distinguishable by its smaller size. 



9. Tanagra cyanoptera (Vieill.) 



T. nayaca, Burm. I. c. p. 479. 



Six skins of this species, all marked females, and without tlie 

 bright blue on the lesser wing-coverts. 



10. Tanagra striata (Gm.) ; Burm. I. c. p. 480. 



11. GuiRACA GLAuco-c^RULEA (Lafr. ct d'Orb.). 

 Coceoborus glaucocceruhus, Burm. I. c. p. 488. 



Two male specimens only of this highly interesting species. 



12. ZONOTRICHIA PILEATA (Bodd.). 



Z. matutina, Burm. I. c. p. 48G. 

 " Resident."
