" Melanopsis praemorsa f. elongata " mentioned in Peres (1939) [unavailable]

Locality.

Collection stations 80 [tributary rivulet to the river Tensift] and 144 [Oued Sidi Raho, approximately 6 km upstream of its confluence with the Bou Regreg] ( Pérès 1939: 139), Morocco.

Remarks.

First of all, the name as given by Pérès (1939) is a nomen nudum - Pérès apparently considered the expression " elongata " self-explanatory and did not describe it. Moreover, he obviously used the name not as separate taxon but rather as descriptive term to fit existing species into his morphological concept. He even indicated Melanopsis olivieri Bourguignat, 1884 as its “type”.
