We have not seen authenticated specimens of Hornschuch's M. Dregei from the Cape of Good Hope, and in thus referring our species we rely solely on his description, and on the noteworthy fact that it (as well as two other species from the Southern United States, viz. Anomodon Toccoæ and Bruchia brevipes) cocurs also at the Cape (fide Herb. Taylor).
