. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. THE SKELETON OF THE MAMMAL-LIKE REPTILE CISTECEPHALUS 217 only slightly posteriorly. The zygapophyses of the cervicals, particularly the last two, are set close to the neural spine and are tightly interlocked. In what is regarded as the first dorsal vertebra, the transverse process is short and exca- vated posteriorly, so that in lateral view the distal surface of the process is arcuate in outline. In BPI 4086 the vertebral column is complete except for the atlas and the most posterior tail vertebrae
