Remarks – The “exceptional” similarity between Murex contabulatus Lamarck, 1803 and M. gantensis nov. sp. was already noted by SZŐTS (1953). Later STRAUSZ (1974) revised gantensis , and emended it as a subspecies of? P. contabulatus . Based on morphological differences (the teleoconch whorls of gantensis are more constricted at the base and the spines are slightly more curved than that of contabulatus , see MERLE et al. 2011, pl. 115, figs 5–9) the arrangement suggested by Strausz is accepted herein, and? P. contabulatus gantensis is regarded as a geographic subspecies. “ Murex ” contabulatiformis Schauroth, 1865 from the Italian Eocene is a similar form but differs by more angulate whorls.? P. contabulatus gantensis is widespread and relatively abundant in the HPB.

Distribution – Lutetian–Bartonian, Hungarian Paleogene Basin: Dudar, Gánt, Csákvár, Tés, Balinka, Mesterberek, Neszmély, Tatabánya /Felsőgalla.
