Russell and Wickenden (1933, p. 62) referred to Hyrachyus (= Helaletes) intermedius and isolated M* from the late Eocene Swift Current fauna, Saskatchewan, Canada. National Museum of Canada No. 8659 more closely resembles M^'s in Colodon than Helaletes, which well accords with its late Eocene age. The tooth is slightly larger than known M^'s in Colodon kayi, corresponding in size to small Colodon occidentalis.
