[38] This group might well have been the same as that seen on Dec. 18, 1968. [Illustration: _Figure 2.--A pack of four blacks with two grays (first and third).

Goldman examined the skulls only of 10 Minnesota specimens assignable to _lycaon_ and only one referable to _nubilus_. Because wolves in the known range of _nubilus_ are thought to be extinct, and because the animals in northeastern Minnesota are legally unprotected and subject to a control program, it seems highly desirable that the question of their taxonomy be studied intensively while specimens are still available.
