Since the above description was drawn up, Miss Wilman, Curator 

 of the McG-regor Museum, Kimberley, lias kindly placed at my disposal 

 for study the large series of specimens collected by her in Gordouia, 

 Becliuanaland, and another large series from Warrendale, near East 

 London, collected by Mr. Addison. These additional specimens throw 

 fresh light on the variation of the species, and doubts on the validity 

 of my recently described E. aspera. 



I will deal first with the Warrendale series (58 specimens). 



The upper head-shields are sometimes smooth, more often some- 

 what rugose, and in a few specimens almost as much as in the types of 

 E. asioera* ; the prefrontals are separated from each other in 20 

 specimens, and a complete series of granules borders the inner side 

 of the supraoculars in 14. The chin-shields are asymmetrical iu 4 

 specimens : 4 on one side and 5 on the other ; one has 5 shields on 

 each side, the 2 first pairs in contact in the middle ; among the 

 specimens in which the shields are normal in number, 3 have only the 

 first pair in contact with each other, and 3 have the three anterior 

 pairs meeting on the median line. The anterior border of the ear 

 is always more or less denticulated. The scales, whicli vary in 

 number between 58 and 75 across the middle of the body, are always 

 strongly keeled. 



These specimens are nearly all highly coloured, reddish brown 

 or coppery red, with the ocellar markings, as described above, well 

 marked ; some have one or two pairs of interrupted dark brown or 

 black strea.ks on the body ; a lateral series of 4 to 6 blue ocelli is 

 present in a few. One specimen, a female, is uniform reddish brown 

 above, with a white lateral streak passing through the ear. The lower 

 surface of the tail is sometimes of a bright pink colour. 



'I'he Gordonia series consists of 60 specimens : 13 from the Lower 

 Norob, 8 from the Lower Molopo, and 39 from Ky Ky, all pale greyish 

 or sand-colour, more reddish on the limbs and tail, with or without 



* I note the same thing in single specimens from Emmaus, Enslin, and 

 Steynsbiarg' in the Kiinhorley Museum.
