"December 28, 1967."

"The first part of this paper is a taxonomic revision of species of Hyrachyus from the Bridger Formation ... Bridger Basin, Wyoming."

"The rhinocerotoid family Hyrachyidae, which in its last review (Wood, 1934) included four genera and 12 species, is reduced to a subfamily, with one genus and three species, and included in the tapiroid family Helaletidae. Because the European genus Chasmotherium can be traced back to Hyrachyus (via the lineage Hyrachyus modestus (=H. 'stehlini')-Hyrachyus minimus-Chasmotherium cartieri), the monotypic subfamily Chasmotheriinae is transferred to the Helaletidae"--P. 19 & 21.
