. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. GIRDLES AND LIMBS OF DEINOCEPHALIA 301 Jonkeria koupensis Sp. Nov. This new species appears to be very closely related to /. haughtoni, but the differences in the pelvis, as will be evident from the accompanying characterisation, warrant treatment as a distinct form. In the pelvis the pubo-ischiadic plate is probably short (83% of the height as reconstructed); the supra-acetabular part of the ilium is high (264 mm.) and the antero-posterior length of the iliac blade is very short (282 mm.), so that the height is 93% of the length; the anterior iliac process is fairly short, but appears shorter than it really is because of its strong eversion antero-laterally, and is fairly high; the posterior process is short and fairly low, with its postero-ventral edge moderately strongly folded over to form a fairly strong ilio-fibularis ridge on the outer face; this ridge is directed obliquely upwards, with its upper end not strongly bulbously thickened; a slight groove on the inner face of the everted anterior iliac process indicates the attachment of a rib anterior to the main sacral rib; antero-posteriorly the outer face of the iliac blade is deeply concave. The antero-ventral edge of the pubis is strongly everted, with the tuberculum pubis confluent with the thickened part of the antero-ventral edge, which stretches to the median line where the pubes meet, but do not form a real symphysis. The ischium is not preserved but probably is as reconstructed. The ulna has the distal two-thirds preserved; it is a massive bone with the dorsal lip of the sigmoid face developed into a massive swelling in its preaxial part. Type: 9004. A good pelvis, lacking only the ischia (Fig. 87) and the distal two-thirds of the ulna. Klein-Koedoeskop, Beaufort West. Low Tapino- cephalus zone. Coll. Boonstra. Referred specimen: 11983. An isolated ilium (Fig. 88). Abrahamskraal, Prince Albert.
