ORNITHOLOGICAL OBSERVATIONS 
7. Gyrola, Bp. 1851. 
G. chrysoptera, Sw. 
8. Euprepiste, Sclater (1851). Callospiza, Bp. 
E. braziliensis (Linn.) 
9. Pipridea, Sw. (1827). Procnopis, Bp. nec Cab. 
P. melanonota (Vieill.) 
In the last division, there is considerable difference in form, and 
I believe it to be a good genus. It was with much hesitation I 
previously included the type species in the genus Calliste. My 
Calliste castaneoventris will be a second species of the group. 
C. vassori goes better, I think, with C. argentea, atricapilla, &e. 
P. 21. I will not now enter into the oft vexed and yery difficult 
question as to the correct names of the three Bishop Tanagers, but 
it is a great error to suppose that 7’. olivascens of Licht. is the 2 of 
T. ornata, Sparm., the yellow-shouldered species, Prince Maximi- 
lian, in his Beitrage z. Nat., gives descriptions of the és and 9s of 
both species. Tanagra palmarum, Pr. Max. (1821) = 7. olivascens, 
Licht. (1823), is a widely distributed species, rather variable. 1 
have examples from Rio de Janeiro, Para, Cayenne, and Trinidad. 
The other, 7. ornata, Sparm. (1787)= 7. archiepiscopus, Desm. 
(1805), is from Brazil only. 
P. 22. Dubusia gigas, that is Tanagra montana from Bogota, 
Bp., has been well figured and described by Sir W. Jardine, Ill. 
Orn. pl. xliii. (1841) as Tanagra cucullata. A skin of M. Ver- 
reaux’s, so marked, I can hardly distinguish from Tanagra eximia, 
Boiss, p. 25. Comarophagus is a synonymic genus to Tachyphonus, 
the type being 7. leucopterus, and cannot be used in any other sense. 
P. 29. Tanagra dominica, Gm., is the true type of the genus 
Dulus, Vieill., and not Turdus palmarum. See Mr. Strickland’s 
observations on this subject in the present number of Contributions.
