 [Two adult males from S. Martin Texmelucan, State of Puebla (De- 

 cember, 1884, and January, 1885), agree strictly with other Mexican 

 examples in those characters which separate S. azurea from S. sialis.] 

 These consist in (1) the decidedly more greeuish shade of the blue, 

 (2) decidedly lighter and less purplish tint of the breast, etc., and (3) 

 the encroachment of the latter over the malar region and sides of the 

 neck. In S. sialis the malar region is wholly blue, like the auriculars, 

 the chin itself usually blue, and the sides of the neck are mostly blue. 

 In 8. azurea, on the other hand, the chin and anterior portion of the 

 malar region are whitish, the posterior half or more of the malar region 

 cinnamon-rufous, like the throat, and the sides of the neck chiefly cin- 

 namonrufous, this color even sometimes nearly meeting across the 

 cervix. The two specimens measure as follows :
