ABSTRACT

A preliminary description of the vocal repertoire of Graphiurus parvus is presented together with a survey of published data on vocalization in other species of the Gliridae. All species studied have a relatively rich vocal repertoire with tonal and noisy vocalization types. Graphiurus parvus vocalizations can have frequency components in the range from about 1 kHz to well into the ultrasonic range above 20 kHz. Hypotheses on the homology of the various vocalization types of the Gliridae are hardly possible.
