This distinct species appears to be allied to T. valida Boc. and T. liodon Thos., sharing with them the unusual shallowness of the incisive grooves *, but it is easily separable by its much larger skull and white-tipped tail. Externally it has a close resemblance to Gerbilliscus boehmi Noack, to which Dr. Matschie appears to have referred it t, but its single incisive groove and much larger bulla? readily distinguish it from that animal. 14.
