. Bonner zoologische Monographien. Zoology. 7 Among the rodents, e. g. ground squirrels and marmots, all types of lethargy as well as the largest number of "sleeping" species can be found (Bartholomew and MacMillen 1961, Cade 1964, Hudson 1964 a, 1967, Hudson et al. 1972, Johansen and Krog 1959, MacMillen 1965, Morrison and Ryser 1962 a, 1962 b). Hibernation and/or daily lethargy occurs in bats (Chirop- tera) (Eisentraut 1956); hibernation and/or aestivation in hedgehogs (Insectivora) (Herter 1964 a, b), hibernation or aestivation and daily torpor in tenrecs from Madagaskar (Eisentra

Bears were observed in winter sleep with body temperatures near 31 °C. Skunks and racoons (Carnivora) probably do not enter a lethargic state (Folk et al. 1968). Torpor was also observed in several prosimians from Madagaskar (Eisen- sentraut 1956, 1961, Kayser 1961)..
