Resumen:
Bullar volume was estimated by external measurements for the subterranean genus CtenomysCtenomys (Rodentia, Ctenomyidae) and 24 species of surface-dwelling caviomorphs. Bullae were larger in Ctenomys than in caviomorphs. Larger bullar size may reflect good lowfrequency audition and could be an adaptation for subterranean vocal communication. Estimated bullar volume of the Pliocene rodent Actenomys was intermediate between that ofCtenomys than in caviomorphs. Larger bullar size may reflect good lowfrequency audition and could be an adaptation for subterranean vocal communication. Estimated bullar volume of the Pliocene rodent Actenomys was intermediate between that ofActenomys was intermediate between that of Ctenomys and surface-dwelling caviomorphs, in agreement with the presumed intermediate subterranean lifestyle of Actenomys.and surface-dwelling caviomorphs, in agreement with the presumed intermediate subterranean lifestyle of Actenomys.Actenomys.
