ResumoEcholocation calls of the big naked-backed bat, Pteronotus gymnonotus, are poorly known. At present, only the predominant frequencies have been described from calls emitted by indoor or hand held specimens (Griffin and Novick, 1955; Grinnell, 1970; Simmons, 1973) and a single sonogram (Pye, 1980). We present the first description of echolocation characteristics of P gymnonotus, recorded from a freeflying specimen from Tabasco, Mexico. Distributional implications of this record also are discussed.
