Palpebral vibrissae in the Sumatran rhinoceros (Didermocerus sumatrensis

Authors


Abstract

The erroneous notion that palpebral vibrissae (eyelashes) are wanting from the lower eyelid of the Rhinocerotidae is attributable to Pocock (1914), whose observations were apparently made on museum skins and mounted specimens only. Examination of living and of freshly dead specimens shows such vibrissae to be present upon both eyelids in three of the five extant rhinoceros forms, viz. Rhinoceros unicornis, Diceros bicornis, Ceratotherium simum (Cave, 1969; Van den Bergh, 1970).
