M. Rozeti, is very near Ridgway’s “ecru drab,” and consequently very 
different from the Biskra form. Indeed, the difference is so great that I 
should have considered the latter as a separate species, had it not been 
for the probability that an intermediate coloration will be found in the 
intervening districts.

Head and body 97 millim.; tail 118; hind foot 32; ear 28.
