18. * P. sp. ­ Schornikov & Chavtur, 2001: 91 ( P. attenuata (Brady, 1868); 2002: 94 ( P. attenuata (Brady, 1868); Schornikov & Zenina, 2004b: 214 ( P. attenuata (Brady, 1868) .

Remarks. Soft parts of this species were described by Okubo (1979b) on specimens

from the Inland Sea of Japan and determined by him as Propontocypris (Propontocypris) attenuata (Brady, 1868) . Ishizaki (1963, 1968) determined two different species from the Miocene of Ishikawa Prefecture and from recent bottom sediments of Uranouci Bay, Kochi Prefecture, Japan as Propontocypris attenuata (Brady, 1868) . There is no doubt, that the forms mentioned above are not conspecific to P. attenuata described by Brady (1868) from Mauritius region.
