OSTEOLOGIA AVIUM. 



[TaNAGRINjE. 



Tachyphonus, Vieill. 



Coryphsens, Licht. 

 This species has been divided from Tachyphonus by Bonaparte, in his Conspectus, 

 under the name of Pyrrhota, but the osteology is not distinguishable. 



Tanagra, Linn. 



Ornata, Sparr. 



Cranium with the upper foramen in the orbital septum largest. 



Sternum with the fissures on the posterior margin deeper than in the preceding. 

 In other respects similar.

Lampbotes, 8w. 



Viridis, Spix. 

 Differs slightly from Tachyphonus in having the branches of the furculum more com- 

 pressed, and the process at their juncture not so long. 



Nemosia, Vieill. 



Flavicollis, Vieill. 



Differs from the other Tanagrince by the greater proportionate length of the 

 metatarsi, and in the orbital septa being divided by a very narrow strip of bone. 



Nemosia ruficapillus, Vieill, is similar to the above, but rather smaller.
