 This race, of which I have, through the kindness of Professor 

 Barboza du Bocage, been allowed to examine the typical specimen, 

 can only be considered a pale-grey form of Antlius rufulus, which 

 it would appear to replace in certain parts of South-western Africa. 

 I have referred three specimens in the Museum Collection to this 

 race, the measurements being as follows : —
