Tliesc specimens arc particularly iiiturcslinjr, as they como from tlie ty|iical 

 locality. 



S. a. ivallacii is a very slightly differentiated form, but may be distinguisbed 

 from 6'. a. amazoiuim by its purer green back and by the duller, less rufescent outer 

 webs of tlie (juills. The crown is scarcely washed with rnt'ous, and there is no 

 rufous tinge on the throat. As a rule, breast and abdomen are of a paler, rather 

 more greyish green colour than in S. a. amazoimm, but some specimens are hardly 

 different on this score. 



A series from I'ritish Guiana (Caniacusa, Bartica Grove, R. ('arimai)g), and 

 two adult specimens from the ('aura Kiver, Veue/.., agree with those from I'an'i 

 in the colour of the head and wings, but the back is decidedly darker, more 

 brownish green, almost as dark as in S. a. amazonum from Upper Amazonia, and 

 the throat and foreneck are tinged with brownish. These birds are thus somewhat 

 intermediate between S. a. amazonnm and .S'. a. wallacii.
