have been preserved, and this is the part of the state in which one would look for the typical form, the problem of determining the species that formerly inhabited this region is not an easy one to solve. The northern limit of the range of the typical form has only been vaguely given by the different authorities. Thus Hahn' says " from the region of the Great Lakes," Rhoads' states that it occurs "from southern New York and Michigan," and Seton' gives it approximately the two southern tiers of Michigan counties in his map of the range of the species. Apparently none of these statements are based upon definite information, as we have been unable to find any specimens or information that would lead us to believe that the typical form ever occurred in Michigan even in the southernmost counties. There are two skulls from Wexford county in the museum that are evidently to be referred to variety borealis, the lower row of cheek teeth measuring 83 mm.4 in one and 79 mm. in the other, which has not yet acquired the rear lobe of the third molar. This confirms the opinion held by most writers that the northern form is found in the northern part of the lower peninsula. There are also in the collection, however, a skull from Livingston County (No. 5240) and sub-fossil jaws from Washtenaw County (No. 42,532) and Branch County (No. 42,531) in which the lower row of cheek teeth measures 83 mm., 82 mm. and 90 mm., respectively. These specimens with the statements of former residents5 of Washtenaw and Wayne counties that the deer of these counties had a gray coat in winter seems to constitute pretty clear evidence that the variety borealis formerly ranged 'Hahn, W.
