A rare case of ‘diprosopus monauchenos’ is reported in a newborn calf that died soon after birth. The ‘diprosopus’ consisted of four eyes (tetraophthalmus), two pairs of nostrils, two mouths, each with a tongue and two pinae. The two faces were fused caudally by a single parietal bone and joined ventrally by the medial rhami of the mandible. It was delivered from a five year-old multipara cow. Necropsy revealed normal thoracic and abdominal viscera. The limbs were also normal.
Key words: Cranial duplication, diprosopus monauchenos, cow, calf.
