daque obscui-ioribus, dorsi colore limbatis : subtus dilutior, 

 flavicans, tectricibus subalaribus albis. 



Hob. Panama {M' Cleannan) ; western coast of New Granada, 

 Buenaventura {Hicks); Veragna (^rce); Costarica (Hoffmann). 



I have nine males and three females of this bird before me, 

 amongst which are the types of S. semicollaris, S. hicksii, S. for- 

 tipes, and S. collaris of Mr. Lawrence. I have likewise examined 

 a large series from Panama and Chiriqui in the collection of 

 Salvin and Godman, There is much variation in the amount of 

 the white on the throat and neck collar ; but I am unable to di- 

 stinguish more than one species amongst them all. This must 

 bear Bonaparte's name aurita, as the typical example oi S. aurita 

 in Mus. Paris clearly belongs to it, though the locality (Brazil) 

 attributed to it in the ' Conspectus ' is no doubt erroneous. 



It is difficult to distinguish the female of this species from the 

 corresponding sex of S. corvina.
