In the young the subdigitai lamellae and the scales on the 

 soles are distinctly keeled, spinose. M. chanleri, Stejneger, based 

 on a young specimen from the Tana River, is to be added to 

 the synonymy of this species. 



27. Mabuia hildebrandtii, Ptrs. — Brava; a single specimen. 



28. Lygosoma laeviceps , Ptrs. — Brava ; a single adult spe- 

 cimen. 



28 scales round the body, dorsal faintly tricarinate. I am now 

 convinced that Peters's Euprepes laeviceps (1874) and Giinther's 

 Sepacontias modestus (1880) belong to the same species, the for- 

 mer being founded on a young specimen, the latter on an adult. 



29. Lygosoma sundevallii , Smith. — Lugh ; between Matagoi 

 and Lugh. Between Comia and Matagoi ; numerous. 



24 or 26 scales round the body. 



30. Ablepharus boutonii, Desj. — Brava; several specimens, 

 belonging to the var. peronii. 



Opliidia. 



31. Typhlops cuneirostris, Ptrs. — Web; a single specimen. 



32. Python sebae, Gm. — Pozzi Meddo-Erelle ; a single young 

 specimen. 



33. Eryx thebaicus , Reuss. — Brava ; a single specimen. 



34. Lycophidium capense, Smith. — Between Comia and Ma- 

 tagoi ; a single specimen. 



Black above and below , scales speckled with white on their 

 borders. 



35. Boodon lineatus, D. and B. — Brava ; several specimens. 



36. Zamenis brevis, Blgr. — Between Matagoi and Lugh ; a 

 single male specimen (V. 166; C. 90). 



37. Philothamnus semivariegatus, Smith. — Lugh and between 

 Comia and Matagoi ; several specimens. 



Uniform green or with small black spots. 



38. Dasypeltis scabra. L. — ■ Between Comia and Matagoi; a 

 single male specimen of the typical form (Sc. 25 ; V. 208; C. 62). 



39. Tarbophis obtusus, Reuss. — Lugh ; two specimens.
