Since the writer's report on “The Subarctic Odonata of North America” was published, several collections have been received from localities included within the territory covered in that paper, which add materially to our knowledge of the dragonfly fauna of the Hudsonian Zone on this Continent. Most of these collections are from the Northwest Territories but a few are from northern Alberta and Newfoundland.

In the fall of 1965 a geophysical exploration program, in the Pine Point area, Northwest Territories, Canada, revealed indications which led to the discovery of 11.2 million tons of ore grading 11.7 percent combined lead and zinc in two separate ore bodies. The ore bodies are relatively flat‐lying although irregular in plan and section. They lie in limestones and dolomites, some reefoidal, of Middle Devonian age and are generally conformable to these sea sediments. The basic discoveries were effected by a time‐domain, induced‐polarization survey. A subsequent gravity survey proved to be of considerable value in guiding the extensive drilling program which followed and in predicting the amount of ore to be expected in each body. Despite a high marcasite content, the ore bodies did not respond appreciably to electromagnetic induction methods. This is attributed to the mode of distribution of the various sulfide minerals in the deposits.
