V. Sepsina (Bocage). 



1. Sepsina angolensis (Bocage, Jorn. Sc. Math. &c. Li3b. 1866, 



p. 62). 

 Angola. 



2. Sepsina grammica(Coye, Proc. Ac. Nat. Sc.Philad. 1868,p.318). 

 South-west Africa. 



VI. Amphiglossus (D. &B.). 



1. Amphiglossus astrolabi (D. &B.). 

 Madagascar. 



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, ? Gongylus polleni, Thyrus boyerii. 



/3. 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. 



2. 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 sphenopsi- 

 forme" (A. Dum. Arch. Mus. x.p. 180, pi. 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. meri- 

 dionalis 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 varie- 

 ties 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, aud there is no serrature of the mar- 

 gin 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 (I. c.) 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
