This geograpliical race is separated from true massaicus by the 

 more reddish average coloration. While many examples of each 

 race are indistinguishable, the lots as a whole are of quite different 

 color. The richest colored examples are from Wambugu and Fort 

 Hall. There is a great range of individual variation in the intensity 

 of the reddish suffusion.
