Abstract
    Sympatric occurrence of Delphinus capensis and D. Delphis is demonstrated for Gabon and Angola based on cranial evidence. As in eastern Pacific common dolphins, key characteristics include cranial size, rostrum length relative to zygomatic width and tooth width. Two phenotypes of the proximal part of the palatinal ridge are found to be discriminatory between both Delphinus species.
