Habitat. — The types are from the " Northern and Western parts of 

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

 to Bechuanaland (G-ordonia) and Angola (Benguella). 



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

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

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

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

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

 examples of E. lineo-ocellata, var. pulchella, 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 species and the preceding, a character 

 which, although liable to exceptions, goes hand iu 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 iu the Nortli 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 tlie question will have to 

 be reconsidered, and E. namaquensis, as well as E. henguelensis, may 

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