a bold headland on the S.W. coast of England, county of Cornwall, on the English Channel, N. Lat. 49° 57' 40", W. Long. 5° 11' 5". This is the most southern land in Britain, and generally the first sighted by vessels entering the Channel. It is surmounted by two fixed lights, the one 221 feet, and the other 225 feet above sea level. The rock is formed of hornblende and mica slate, and constitutes a rugged and precipitous coast. About a mile to the W. of the point is Old Lizard Head, with the dangerous rocks to seaward known under the name of the Stags. The Ocrimum of Ptolemy was either this head or Lizard Point.
