Specimen withweak ornament on inner whorls, x 0,85. The suture lines of the Zululand specimens are similar to those of the largeseptate specimen figured by Collignon (1948, pi. 15) and of the holotype (Col-Hgnon 1932: 37, fig. 20), although the elements in the former are generallymore blocky. The Pondoland specimens, SAM-PCP5717 (Figs 207, 213A),SAM-PCP 5883 (Fig. 212) and NMB-Dl 191 (Figs 204,213B), have more incisedlobes and saddles and narrower

In accordance with the procedurefollowed above, the species may be divided into two subspecies on the basis ofthe suture line and more or less geographic restriction. The Zululand specimenswith blocky elements are to be referred to S. condamyi condamyi, whereas the 268 ANNALS OF THE SOUTH AFRICAN MUSEUM ^*%»^. Fig. 207. Submortoniceras condamyi (Collignon, 1948). Holotype of subsp. nov. Specimen with strong ornament on inner whorls, x 0,62. Pondoland specimens with narrower, more incised saddles and lobes are to bereferred to S. condamyi umzambiense ssp. nov. (holotype is SAM-PCP5717(Fig. 207) from Bed A7 locality 1, Umzamba Cliff, at the Santonian/Campanianboundary). Development of tuberculation on the outer whorls, following the relativelysmooth phragmocone stage in some of the Zululand specimens, SAS- CRETACEOUS FAUNAS FROM SOUTH AFRICA 269 A2084, Z1140 (Fig. 209), is comparable with the trend displayed by S. anguste-umbilicatum Collignon; the whorl section in the latter species, however, seemsto be more compressed, although the narrow, finely splayed lateral lobe (L) iscomparable with S. condamyi umzamhiense ssp. nov. SAM-PCZ5893 (Fig. 206) has lateral ornament on the inner whorls verysimilar to that of S. renniei (cf. Collignon 1948, pi. 17 (fig. 1)), but
