 of neck long, thin, and somewhat paler than back ; front of 

 face rather darker brown than back; feet blackish, with 

 narrow white hoof-bands ; tail thin, brown above, like back,

 parts of West Africa. The Shari Valley sing-sing has, 

 however, been separated as tschadensis, and other named 

 forms in the list on pages 234-238 are also based on 

 modifications of the sing-sing.
