These species may be arranged in the following series, according to the degree of development of the limbs :- a. Four limbs well developed: Gongylus ocellatus, ? Gongylus igneocaudatus, 1 Gongylus polleni, Thyrus boyerii. 13. Four feeble limbs, but with 5 toes : Sphenops sepsoides, Seps capensis, Amphiglossus. y. Four limbs, with less than 5 toes. Toes 4-4 : Gongylus viridanus. Toes 2 - 4 : Sphenops meridionalis. Toes 3-3 : Sepsina, Seps tridactylus. Toes 2-3 : Seps mauritanicus. _. Four rudiments of limbs, without toes: Seps monodactylus. e. Only two two-toed hind limbs : Scelotes. SPHENOPS MERIDIONALIS. I am obliged to propose this name for " Anisoterma sphenopsiforme" (A. Dum. Arch. Mus. x.p. 180, pl. 15. fig. 3), as the genus is identical with Sphenops, so that the original specific name cannot be retained. Sphenops sepoides has 5-5 very small toes ; in S. meridionalis the toes are still more rudimentary, and reduced in number to 2 - 4 . Otherwise the resemblance between the two forms is so great that one would have been justified in describing them as varieties of the same species, if no other distinctive character could have been discovered. However, I find that, in the northern form, the external cleft of the mouth is continued to the ear, and has a serrated margin. In S. meridionalis there is a distinct space between the angle of the mouth and the ear, and there is no serrature of the margin of the mouth. The typical specimen is said to have been received from the Gaboon. The British Museum obtained by purchase two specimens from M. Parzudaki, who stated that he had received them from Senegal. SEPS (GONGYLUS) CAPENSIS, Smith, Zool. S. Afr. Append, p. 10. Sir A. Smith has presented to the British Museum two small Lizards contained in a bottle, which is labelled in his own handwriting " Gongylus capensis." In his description (/. ci) he distinctly refers to a single specimen, two inches long, without the tail, which was lost. One of our two specimens is, indeed, of that size, and without |
