Remarks

Keith (1911) is a letter to Nature, recounting portions of correspondence bearing on the discovery and naming of the Gibraltar 1 (Forbes Quarry) specimen. Keith (1911) recounts the date of discovery as 1948, nine years before the discovery of the type specimen. Calpicus is the ancient name for the rock of Gibraltar and is suggested by H. Falconer in a letter quoted from by Keith (1911).
