Arrowed locations show significant differences in lateral outline between B. longicaudata and B. sapucariensis. field includes the holotypes of B. angulata Grekoff, B. armata Reyment, B. kulatturensis Guha, and B. dumoni Bismuth & St. Marc, as well as several of the morphotypes recorded by Grosdidier (1979) from Iran. At this stage, with the exception of the topotypic material illustrated by Krommelbein (1964), no consistent subdivision can be made between many members of the two populations other than one based on overall size. Bate (in Bate & Bayliss 1969) recorded B. aff. sapucariensis from the Upper Turonian of Tanzania. In the subsequent discussion to this paper, Bate (p. 164) compares his specimen more closely with B. longicaudata. An SEM photograph of the more elongate specimen recorded by Bate (BMNH Io790) (Fig. 16B) confirms this closeness, and I regard this as the earliest record of Chapman's Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
