Previous work that recorded 75 species of Scaphopoda in New Caledonian waters is augmented with study of new material from several expeditions. The number of species in the region is increased to 115. Of the 40 additional taxa, 28 are described as new, 7are new records and 5 remain unidentified. Material from New Caledonia previously identified as Antalis phaneum (Dall, 1895) is now determined as A. albatrossae n. sp.; material previously identified as Compressidentalium sedecimcostatum (Boissevain, 1906) is now determined as C. clathratum (Martens, 1881); Episiphon virgula (Hedley, 1903), formerly treated as a synonym of Dentalium subrectum Jeffreys, 1883, is revalidated; material previously identified as Entalina mirifi ca (Smith, 1895) is now determined as E. dorsicostata Lamprell & Healy, 1998; Fissidentalium transversostriatum (Boissevain, 1906), previously synonymized with F. shoplandi (Jousseaume, 1894), is revalidated and the material previously reported from New Caledonia as the latter in fact belongs to the former. New synonyms: Episiphon jamiesoni Lamprell & Healy, 1998 is synonymized with Gadilina insolita (Smith, 1894); Dentalium subrectum Jeffreys, 1883 and D. bisinuatum André, 1896 are synonymized with Laevidentalium eburneum (Linné, 1767); Laevidentalium arnoldi Lamprell & Healy, 1998 is synonymized with L. houbricki Scarabino, 1995; Bathoxiphus steineri Lamprell & Healy, 1998 and B. stanisici Lamprell & Healy, 1998 are synonymized with Solenoxiphus striatulus Chistikov, 1983. New records from the New Caledonian region: Striodentalium thetidis (Hedley, 1903), Fissidentalium waterhousae Lamprell & Healy, 1998, Calliodentalium crocinum (Dall, 1907), Gadilina pachypleura (Boissevain, 1906), Laevidentalium eburneum (Linné, 1767), Laevidentalium (?) sominium Okutani, 1964, Megaentalina mediocarinata (Boissevain, 1906).
