Habitat. — The types are from tlie " Northern ;iik1 Western parts of 

 Cape Colony." The species is now known from Little Naniaqualand 

 to Bechuanalaud (Gordonia) and Angola (Bengnella). 



It is necessary to observe that my identification of E. undata rests 

 on Sir Andrew Smith's description of 1838, in which 10 longitudinal 

 rows of ventral plates are ascribed to the species, not 12 or 14 as 

 stated by Diimcril and Bibron, from specimens lent by Smith himself. 

 These, as well as the one figured in the " Illustrations," are striated 

 e.xamples of E. Uneo-ocellata, var. 'puJcltdla, which, owing to the 

 markings, were confounded by Smith with his E. undata. The true 

 E. undata is not among the specimens presented by Smith to the 

 British Museum, but the lizard received from Lord Derby, previous to 

 1845, is probably one of the original types, given away by the former 

 before the publication of his "Illustrations." It is a great pity that 

 the types of so many of Smith's species were thus scattered about, with 

 the result that some have been lost. 



Were it not for the difference in the number of longitudinal series 

 of ventral plates between this si>ecies and the preceding, a character 

 which, although liable to exceptions, goes hand in hand with a difference 

 in the lower eyelid, I should have hesitated to retain E. undata, as a 

 species distinct from E. namaquensis, in view of the variation in 

 E. guttulata. But whereas in the North African species the extremes 

 in the condition of the lower eyelid are completely connected, no transi- 

 tional forms are known to occur in South Africa, although it is quite 

 possible that such may eventually be discovered when larger series of 

 specimens have been collected, in which case the question will have to 

 be reconsidered, and E. naniaquensis, as well as E. henguelensU, may 

 have to be degraded to the rank of varieties of E. undata, which name
