the banks of the Vaal River, Potchefstroom District, 24th March, 1917. 
Also a series of five younger specimens from the same colony, showing 
the same characters ; but unfortunately the only female captured is not 
mature and the number of mammae is not known. 
I have named this animal after Mr. Robert Palk, who materially 
assisted me in effecting their captvre. 
Besides these specimens, two others were captured in another 
colony, an adult female and a young adult male, which have all the 
characters, including the number of mammae, of G. natalensis mihi, 
though they are somewhat paler on the muzzle. This again illustrates 
the necessity for carefully noting which colonies specimens were cap- 
tured in, each species apparently living upon a particular vegetable 
food.
