10. Buarremon chrysopogon, (Bonaparte.) 



Chrysopoga typica, Bonap. Consp. A v. i. p. 480, (1850.) 



Ataleptes chrysopogon, Bonap. 



Buarremon gutturalis, Lafres., Rev. Zool., 1842, p. 97? 

 This bird seems to be regarded by authors as entitled to the name here 

 adopted, but specimens in the Academy Museum bear Paris labels : " Arremon 

 gutturalis, Lafres." Dota, Costa Rica, July 24, 1864. Mr. J. Carmiol. 



11. Chlorospingcs albitemporams, (Lafresnaye.) 



Tachyphonus albitemp oralis, Lafres., Rev. Zool., 1848, p. 12.

Saltator rubicoides, Lafres., Rev. Zool., 1844, p. 41. 

 Grecia, Costa Rica, Dec. 12, 1864. Mr. Carmiol. 



13. Tachyphonus DeLattrei, (Lafresnaye.) 



Tachyphonus DeLattrii, Lafr., Rev. Zool., 1847, p. 42. 

 One specimen only of this species in very fine adult plumage, but not dif- 

 ferent in any respect from others in the Academy Museum from New Grenada. 

 This bird is scarcely a Tachyphonus, nor congeneric, properly, in my opinion, 

 with any other bird with which I am acquainted. Paqua, Costa Rica, March 

 23, 1865. Mr. J. Carmiol. 



14. Tachyphonds luctuosus, D'Orbigny et Lafresnaye. 



Tachyphonus luctuosus, D'Orb. et Lafres., Mag. Zool., 1837, p. 29. 



D'Orb. Voy. Am. Ois., pi. 20. 



Numerous specimens, in nearly all of which the males have a partially con- 

 cealed but well defined coronal spot of pale yellow, a character not previously 

 known in this species. Those evidently in quite mature plumage are larger 

 than D'Orbigny's specimens in the Academy Museum, but not larger than his 

 figure above cited. The coronal spot is not present in D'Orbigny's specimens, 

 nor in numerous others which I have examined, and I suspect it appears only 

 at maturity, or in full nuptial plumage. No other peculiar character is appa- 

 rent to me in the present specimens. Angostura, March 10 and June 7, 1864, 

 and March 16, 1865. Mr. J. Carmiol. 



15. Tan agra Diaconus, Lesson. 



Tanagra Diaconus, Less., Rev. Zool., 1842, p. 175.

18. Lanio ledcothorax, Salvin. 



Lanio leucothoraz, Salv., Proc. Zool. Soc. London, 1864, p. 581. 



Numerous specimens, all of which present with much uniformity the peculiar 

 characters of this curious species as given by its discoverer, that excellent 

 naturalist and most judicious and liberal patron of the zoological sciences, 

 Osbert Salvin, Esq., of London. 



Angostura and Payariqui, Costa Rica, March, 1865. Mr. J. Carmiol. 



19. Euphonia fulvicrissa, Sclater. 



Euphonia fulvicrissa Sclat., Proc. Zool. Soc. London, 1856, p. 276. 

 Specimens apparently quite identical with others from New Grenada in Oipt. 

 Michler's collection in the Smithsonian Museum.
