Dermal denticles on side of tail not larger than those on rest of body. Various subgenera are often recognised and even raised to full generic rank (see Garman, Mem. Mus. Comp. Zool., vol. xxxvi, 1913), but so far as the South African fauna is concerned a subdivision of the genus seems unnecessary. The species are all very similar in general facies, yet the 10 South African species would be distributed into at least 5
