Smith (1891) places africanus, natalensis, verreauxianus, and 

 vaalensis in the synonymy of caffra ; Simpson (1900), while further 

 admitting navigioliformis and rectilinear is, considers africanus and 

 vaalensis worthy of varietal rank . Dr. Haas writes that verreauxianus, 

 navigioliformis, natalensis, rectilinearis, africanus, vaalensis, and 

 pentheri are inseparable from caffra, and that zeyheri and cyamus 

 must also belong to this species.
