274 PROCEEDINGS OF THE ACADEMY OF 



D'Orb., Voy. Am. Ois.,pl. 58, fig. 1. Reich., Voeg., fig. 3760, 3761. 



Specimens labelled "Bolivia," one of which is from M. D'Orbigny's col- 

 lection. A curious and peculiar species, not intimately allied to, nor re- 

 sembling any other. It is accurately figured in the plate of M. D'Orbigny, 

 cited. 



C. Pyrrhodiglossa. 



Diglossa mystacalis, Lafresnaye. 



Diglossa mystacalis, Lafres., Rev. Zool., 1846, p. 318. 

 Reich., Voeg., fig. 3756. 



From Bolivia. One of the largest species, easily recognized by its black 

 plumage, and rufous stripe from the base of the under mandible, on the side 

 of the neck, and its rufous under tail coverts. Accurately described by the 

 Baron Lafresnaye, and faithfully represented in the plate of Dr. Reichenbach's 

 great work, as cited. 



6. Diglossa brunneiventris, Lafresnaye. 



Diglossa brunneiventris, Lafres., Rev. Zool., 1846, p. 318. 

 " Diglossa brunneiventris, Des Murs," Lafres., as above. 

 Des Murs, Icon. Orn., pi. 43. 



One specimen from Bolivia, presented by the Smithsonian Institution, in 

 the Museum of which I have seen others. This species is allied to the imme- 

 diately preceding (D. mystacalis), but is smaller, and has the entire under 

 parts fine rufous- cinnamon, which are black in that species. This bird may 

 be the adult of D. sittoides. * 



D. Cyanodiglossa. 



7. Diglossa personata, (Fraser). 



Agrilorhinus personatus, Fras., Proc, Zool. Soc, London, 1840, p. 23. 

 Uncirostrum cyane^m, Lafres., Rev. Zool., 1840, p. 102. 

 Diglossa melanops, Tschudi. Wiegm. Archiv, 1844, p. 294. 

 Reich., Voeg., fig. 3752, 3753. 



Specimens labelled "Bogota" and " Columbie," generally very similar to 

 each other, but one specimen, perhaps not adult, has little of the black front 

 cheeks and throat which so strongly characterize this species, those parts 

 being blue, nearly uniform with the entire other plumage. In fact, until un- 

 doubted specimens of the next immediately succeeding (D. indigotica) were 

 received at the Acad. Mus., I had regarded it, doubtfully, as that species, 

 though much too large. This specimen resembles Reichenbach's fig. 3752, 

 cited above. 



8. Diglossa indigotica, Sclater. 



Diglossa indigotica, Sclat., Ann. and Mag. Nat. Hist., xvii. p. 467 (1856).- 

 "Diglossa indigotica, Verreaux MSS." Sclat., as above. 

 Sclater, Cat. Am. Birds, pi. 8. 



Two specimens in a collection from Ecuador recently presented to the 

 Academy by its generous and steadfast patron, Dr. Thomas B. Wilson. This 

 species somewhat resembles the preceding, but is much smaller, and is other- 

 wise quite distinct. It is very accurately represented in Dr. Sclater's beauti- 

 ful plate, to which I refer, above. 



E. Melanodiylossa. 



9. Diglossa Lafresnayei, (Boissoneau). 



Uncirostrum La Fresnayii, Boiss., Rev. Zool., 1840, p. 4. 

 Agrilorhinus Bonapartei, Fras., Proc. Zool. Soc, London, 1840, p. 22. 

 Reich., Voeg., fig. 3757. 



Specimens labelled "Bogota" and "Pasto." The largest of the species 

 enumerated in this paper, though but little exceeding D. mytlacalis. This
