the back, but the auriculars somewhat grayish; lower parts between light 
olive gray and light grayish olive, streaked with fuscous, and on the medial 
posterior portion with olive buff, but the middle of the abdomen plain olive

While this new race is intermediate between Arachnothera affinis affinis 
of Java and Arachnothera affinis modesta of the Malay Peninsula, it is dif- 
ferent enough from both to be separately recognized. It may be distin- 
guished from the latter by its smaller size, darker upper surface, and rather 
darker lower parts. It is the form inhabiting most if not all of Sumatra. 
Arachnothera chrysogenys astilpna, subsp. nov. 
Subspecific characters.—Similar to Arachnothera chrysogenys chrysogenys, 
from eastern Sumatra, but upper parts darker, duller, and less yellowish 
(more grayish); lower surface rather darker.
