Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum . , maintains the same style of ornament describedabove, with thirteen strong, tuberculate primary ribs per whorl. The suture fine is incompletely exposed on SAM-D1187C only. E/L iselongate, rectangular, little incised, and asymmetrically bifid, L is narrow anddeep. Discussion The specimens referred to this species vary greatly in proportions andrelative development of ribs and tubercles, but are linked by coronate form,sparse primary ribs, massive, if variable lateral tubercles, paired outer flankribs, and ventral and siphonal clavi. They match closely with the types ofNeokanabiceras madagascariense CoHignon (1965: 42, pi. 432 (figs 1784-1786))and encompass the predominantly ribbed var. ankinatsyensis Collignon(1965: 43, pi. 432 (fig. 1878)). The authors have Httle doubt that, given asomewhat larger collection, Neokanabiceras apambiense Collignon (1965: 43,pi. 432 (fig. 1788)) would prove to be no more than a very depressed variant ofthis species. 290 ANNALS OF THE SOUTH AFRICAN MUSEUM. •^ 60 CRETACEOUS FAUNAS FROM SOUTH AFRICA 291
