D. sittoides was one of the two species of this genus ob- 

 tained by D'Orbigny in Bolivia, and first described by him 

 and Lafresnaye in 1838. D^Orbigny collected specimens at 

 various points on the Eastern Cordillera of that country, at 

 Chupe, in the province of Yungas, and near the cities of Chu- 

 quisaca and Valle Grande. Bridges met with it also in Bo- 

 livia, at altitudes of from 8000 to 10,000 feet in the province 

 of Cochabamba. 



In 1848 Lafresnaye founded a second species of Diglossa 

 upon Bogota skins, to which he gave the very appropriate 

 name of D. similis, from its striking resemblance to the Bo- 

 livian D. sittoides. Lafresnaye states various minute points 

 of difference between the two forms ; but upon comparison of 

 the series now before me (consisting of nine individuals from 

 different localities), I find that none of these points holds good. 

 Besides that, we have since discovered that this species occurs 

 not only in Columbia and Bolivia, but also in the interme- 

 diate countries of Ecuador and Peru, and likewise extends
