Distribution (if Pelagodiscus allanticus (King). has been discussed recently by Helmcke in his account of the Brachiopods from the 'Deutsche Tiefsee Expedition'. He has .charted all the localities hitherto known; they lie widely scattered over the three world oceans and in the Antarctic. In some places, however, e. g. in the Indian Ocean north of Madagascar and in the Antarctic, only Discinid larvae which have been referred to P. atlanticus have been found. If this reference is correct (and it ought here to be mentioned that already Ashworth (1916) has given reasons against the identification of Eichler's Discinid larva from the 'Deutsche Siidpolar Expedition 1901-03 (Eichler 1911, p. 384-85)), and if all the specimens which hitherto were referred to Pelagodiscus atlanticus actually belong to this species, it may indeed be maintained, that this species is the most and perhaps the only true cosmopolitan Brachiopod known. The fact that this species everywhere in the world is dredged in abyssal regions supports the supposition of its cosmopolitan distribution, because 'fiir die Tiere der tieferen Wasserschichten wild gewohnlich eine weltwreite Verbreitung angenommen' (Helmcke 1910, p. 231). The North Atlantic specimens here examined agree in every detail, as far as I can judge, with the original description of P. atlanticus from the waters west of Ireland given by King (1868, p. 170), Jeffreys (1876 a, p. 252) and Davidson (1886, p. 200).
