Hahitat. — The types are from tlie " Northern ami Western parts of 

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

 to Bechnanaland (Gordouia) and Angola (Beng-uella). 



It is necessary to observe tliat my ideutification of E. undata rests 

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

 rows of ventral plates are ascri))ed to tlie species, not VI ov 14 as 

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

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

 examples of E. Ihieo-oceUata, var. pnJcliella, which, owing to the 

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

 E. undaia 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 

 tlie result that some have l)een lost. 



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

 of ventral plates l)etween this species 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 K. undata as a 

 species distinct fn»m E. tiaiiiaqtiensis, in view of the vai'iation in 

 E. (juttulata. But whereas iu the North African species the extremes 

 in the condition of the lower eyelid are com])letely connected, no transi- 

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

 possil)le that such may eventually be discovered when larger series of 

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

 be reconsidered, and E. uamaquensis, as well as E. I/enguelensis, may 

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