A parcelling of the telencephalon of I. paucisulcus (Amphibia, Gymnophiona (Caecilia)) was performed with a quantitative cytoarchitectonic method. Ten different regions were delineated and compared with earlier reports on telencephalic regions in anurans, urodeles and caecilians. The most striking differences between the brain of Ichthyophis and other amphibian brains are the high level of morphological differentiation of the accessory olfactory bulb in Ichthyophis and the large extension of this brain region. This feature may be a correlation of the advanced development and the particular structure of Jacobson's organ in this species.
