In his survey on facial vibrissae in mammals, Pocock(1914) noted eyelashes being present in Rhinocerotidae on the upper eyelid only. Recently, Cave (1969) described the existence of eyelashes also on the lower eyelids in three species of rhinoceros, including the African Black or Hook-lipped rhinoceros. In the five living specimens of Diceros bicornis examined by Cave (1959: 253) the lower eyelashes were found to be 'relatively fine, but very short hairs, somewhat irregularly disposed'. On 27 July 1964 I was able to observe and photograph at very close range the eye region of an African Black rhinoceros then living in the Zoological Gardens of Antwerp, Belgium.

On 27 July 1964 I was able to observe and photograph at very close range the eye region of an African Black rhinoceros then living in the Zoological Gardens of Antwerp, Belgium. The specimen, a female, which had been in the Society's collection since 1956 was estimated to be approximately ten years old at the time of the observation (Gijzen, A., pers. comm.).
