Hiwrocyon Peterson and Megalictis Matthew are more modified forms which, 
however, are apparently related to this group of the Mustelide. One of the 
chief generic differences between dilwrocyon, Megalictis, Oligobunis, and Paroligobunis 
is the presence of the metaconid on M; of the two latter and the absence of it in the 
case of the two former genera. In Paroligobunis the metaconid is situated nearly 
as high up as the summit of the protoconid, and quite closely fused to the latter. 
Some of the Siwalik mustelids (Melivoradon) are also closely allied to this general 
group. I fully agree with Dr. Matthew’s” statements that Mellivora and Gulo are 
the nearest living allies of délwrodon and Megalictis; I would in fact also include 
Oligobunis, Paroligobunis, and possibly the proposed new genus Braciyyate as not 
so very distantly related especially to Hlurocyon and Megdlictis, Sthenictis
