It has been fed in captivity during my six weeks holydays exclusively with Indian corn. It seems to me that due to that lack of variation in food the roots of its teeth grew to an abnormal length, and a large quantity of cement has been deposited in the reentrant angles, tending to deform partially the teeth. Due to this fact therefore the set of teeth of the specimen described cannot be investigated from a systematical point of view. On the skull bones however I was unable to detect any pathological deformation in spite of the most careful investigation so that I was compelled to describe my animal as a new subspecies. Its connection with the Pitymys dacius MILL, is without any doubt, which is proved also by the extraordinary flatness of the skull and by the strongly bent nasalia. It is a pity that MILLER'S description does not give any clew, what is the angle of the nasalia in the case of the P. dacius, but considering that he puts the angle of the nasalia on the P. subterraneus as 11°, and he qualifies them in the description of the P. dacius only as somewhat more bent, I can assume that he would have emphasised more the presence ot an angle more than the double of the former. It is a self-made conclusion out of that, that I consider the angle of the nasalia of the P. dacius hungaricus to be larger than that of the stock type. In the same way I consider also the skull of the P. dadus hungaricus to be Hatter. Adding to all this that the P. dacius hungaricus is larger at the same time, I think it sufficiently justified to give a description of my specimen as belonging to a new subspecies.
