Menabites {Australiella) australis (Besairie, 1930). SAS-Z705. Specimen close toM. {A.) coronata due to depressed, coronate whorl section x 1. (See Fig. 235A.) Unfortunately, the holotype of M. {A) tintanti was figured in lateral viewonly, but it seems to occupy a morphologically intermediate position betweenM. {A)falloti and M. {A) australis, in a sequence leading from a pentatubercu-late stage through quadrituberculate to eventually trituberculate at comparablediameters. Given more material it would most probably be possible to includeM. {A) tintanti in the synonymy of one of the two species. M. {A) subaustralis has the same ornament and whorl section as M. {A.)australis at small diameters, but after 60 mm all ornament weakens, thus differingfrom the latter species.
