The specimen below was identified wilh considerable doubt by 

 Blanford with Dipus macrotarsus of Wagner ; since that time 

 several more specimens exhibiting the peculiar colouration of 

 Blanford's specimen have been procured for the Karachi Museum, 

 and Murray has given the species a new name ; whether it will 

 really turn out to be distinct from the true D. microtarsus which 

 was got from Sinai, can only be settled by a comparison of the 

 specimen below with Wagner's type now probably in the Berlin 

 Museum.
