In a recent article the author discussed the limit of postglacial marine submergence in the northern part of Melville Peninsula. It was suggested that the marine limit in the area, as determined by a number of observations using four different criteria, varied between 450 and 500 feet. Of these four criteria only two, the lowest altitude at which undisturbed ground moraine and perched boulders occurred, were found to be particularly useful. Similar techniques were used during the summer of 1959 to determine the limit of postglacial submergence in the southern part of the peninsula. The observations there are limited to four altitudes in the Prince Albert Hills east of Lefroy Bay and to seven altitudes on the shores of the peninsula between Haviland Bay and Gore Bay. Two additional altitudes, one obtained by Burns near the mouth of Jenness River (the only observation on the east coast south of 68°N.) and the other by Mathiassen between Gore and Haviland bays, comprise all the available information. The location and altitude of each observation is plotted on the map, Fig. 1. .
