Bourguignat 1884 : 116. Type locality. "Dans la source et la riviere de la Moulouiah, a l'ouest de Lalla-Maghnia" [in the source and the river Moulouya, west of Maghnia], Morocco or Algeria. Remarks. Bourguignat denoted the authority as "Bourguignat, 1872, et Letourneux", apparently referring to Letourneux (1876b) . That work is not available to me, but after Crosse (1877 : 33) that record is a nomen nudum. It appears also as nomen nudum in Letourneux (1876a : 48). In addition, Bourguignat listed "Bourguignat. Spec. nov. Moll., no. 198, 1878", which displays the second part of "Species novissimae Molluscorum" ( Bourguignat 1876 ), but which was never published.
