According to Ellerman (1941), the seventy-odd forms of palæarctic rodents that go under the name of “True Hamsters” (family Murinæ, subfamily Cricetinæ) fall into four genera with a total of 18 species: Cricetulus (11), Phodopus (3), Cricetus (1), and Mesocricetus (3), the last two genera being unified by some authors. So far only one species of this important group has been investigated from the point of view of chromosome properties: the Golden Hamster, Cricetus (Mesocricetus) auratus Waterhouse.
