All primates have a calcarine fissure that enlarges the visual cortex of the medial occipital lobe and a lateral sulcus that expands the cortex devoted to somatosensory processing (that is, the sense of body position, pain, temperature, and so on--rather than senses such as vision and hearing).
The presence of the calcarine sulcus in the occipital lobe is also clear, as well as the lateral sulcus between the parietal and temporal lobes.
Carapace: anterior margin with slight median bulge; tegument slightly granulate in females, densely granulate in males; anterior longitudinal sulcus deeply marked; ocular tubercle well defined in middle of carapace, interocular sulcus deeply incised, median eyes 2 diameters apart; lateral sulcus, postocular furrow and posterior sulcus deeply incised.
