Abstract
Galeus longirostris sp.nov. is described based on 46 specimens taken off the southern part of Japan. It is distinguished from all known species of Galeus in having a considerably longer snout. This species is morphologically close to G. nipponensis, which commonly occurs off the southern part of Japan, but differs in having longer preoral length than the mouth width, a bluntly rounded snout, larger pectoral fins, a shorter interspace between anal and lower caudal fins, and a greater number of monospondylous vertebrae.
