1 Heuglin afterwards withdrew this name, as his supposition that the mantle 
was chestnut in both sexes proved incorrect. 
serve to distinguish the northern from the southern race. 
The characters I have given, however, 
Zedlitz (J. f. O., 1914, 
p. 675) has described P. s. deckeri from S. Somaliland, while Oberholser had previously 
described P. s. homopterus from W. Somaliland, but I am unable to separate these 
supposed races from castanonotus.
