Smith (1891) places africanus, natalensis, verreauxranus, and 
vaalensis in the synonymy of caffra ; Simpson (1900), while further 
admitting navigioliformis and rectilinearis, considers africanus and 
vaalensis worthy of varietalrank. Dr. Haas writes that verreauxianus, 
navigioliformis, natalensis, rectilinearis, africanus, vaalensis, and 
penthert ave inseparable from caffra, and that zeyheri and cyamus 
must also belong to this species.
