The general resem- blance of G. Dunni to certain species of DipodiUus is very noticeable. 12. Ammodillus (g. n.) imheUi's, de Wint. Gerhillus imheUis, de Wint. Anc. & Mag. Nat. Hist.

Eather richer and deeper rufous than the type, which was collected by Mr. C. V. A. Peel at Gondar. The tail of that specimen having been imperfect, Mr. de Winton could only say of it " tail darker above than below, rather sparingly haired'?"; but I am now able to record that while it is very sparingly haired proximally, it changes terminally, and has a well-marked brown brush, the hairs of which may attain 8-10 mm. at the tip. But, in addition, a further study of this gerbille convinces me that it cannot properly be included in any of the genera now recognized among the group, the characters of the skull, as detailed by the describer, especially the unique absence of the coronoid processes to the mandible, and the details of the dentition preventing its inclusion in DipodiUus, to which alone its naked soles ally I I.
