Remarks.

Euchondrus septemdentatus ( Figs 13-17 ) is a remarkably variable species in terms of shell shape (see also Haas 1955), and one of the most widespread taxa within the genus ranging from Southern Turkey throughout the Eastmediterranean countries almost reaching the Negev Desert ( Heller 2009; the single record north of Eilat may be due to a carryover by man).

Mousson’s name Chondrus septemdentatus var. borealis ( Fig. 16 ), which comprises the Turkish form of this species was used by Forcart (1940) as replacement name for Pupa septemdentata to remove the secondary homonymy with Jaminia septemdentata Risso, 1826 (= Chondrina avenacea Bruguiere, 1792). For names replaced before 1960, the rule "once a homonym, always a homonym" has to be applied (ICZN § 59). However, the replacement was never commonly accepted, and the name septemdentatus has always been applied for the populations of this species from Israel, the latest example for this use being Heller (2009). This results in a confusion of the correct application of the available names for this species under the condition that the specific identity is accepted. We consider Forcart‘s replacement action as invalid, because he omitted the older name Bulimus triticeus Rossmässler, 1858 ( Fig. 14 ), which is also a synonym of Pupa septemdentata . For this reason we herewith return to use the name septemdentatus for this species in order to eliminate an unstable nomenclatural situation. If this point of view is not accepted, this issue has to be clarified by a ruling of the Commission following § ICZN 59.3.1.
