Unpublished rare occurrences before 31st December, 1971

Abstract

An examination of the specimens kept at the Natural History Museum at Mdina reveals that a number of rare occurrences have so far remained unpublished. Excepting the Egyptian Vulture and the Crossbill, all the occurrences have been recorded less than twenty times in the Maltese Islands. Apart from a list compiled from the Natural History Museum, with the kind permission of the Director of Museums, known and reliably dated specimens in private collections have been included. Unless otherwise indicated, the specimens are all found at the Natural History Museum.
