Discussion This subspecies is very variable, and should be interpreted in terms ofconsanguinity of characteristics predominating in the majority of specimensrather than narrowly defined characteristics present only in the holotype. The stratigraphic occurrence of typical specimens in Bed B at locality 105(Fig. 130), immediately overlying Bed A containing T. presoutoni natalense,may suggest genetic relationship between the two species, as here assumed(Fig. 132). Similarly, the relatively higher stratigraphic occurrence of Sub-mortoniceras woodsi natalense again seems to support genetic relationshipbetween the two. T. soutoni natalense ssp. nov. is of age similar to the predominantly Pondo-land sub
