Abstract

A well developed bulbus olfactorius accessorius is described for Phyllostomus hastatus, Glossophaga soricina, Artibeus jamaicensis and Desmodus rotundus , although no such organ was found in species of Emballonuroidea, Rhinolophoidea, and Vespertilionoidea. This organ receives a myelinated nervus vomeronasalis related to the olfactory epithelium in the organ of Jacobson. The volume of the bulbus olfactorius accessorius is related neither to that of the bulbus olfactorius proper, nor to the size of the animal as a whole, as indicated by comparison with the volume of the myelencephalon. Its connection with the amygdaloid complex, as well as with the organ of Jacobson, seems to suggest a role in sexual behavior.
