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

 of tlie McGregor Museum, Kimberley, has kindly placed at my disposal 

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

 Becliuanaland, and another large series from Warrendale, near East, 

 Loudon, 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. ai^j^era. 



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



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

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

 E. aspera* ; the prefrontals ai'e sejjarated from each other in 20 

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

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

 specimens : 4 on one side and 5 on the other ; one has 6 shields on 

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

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

 first pair iu 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 ami 75 across the midille of tln^ liody, are always 

 strongly keeled. 



Tliese specimens are nearly all highly coloured, reddish lirown 

 or coppei-y red, with the ocellar markings, as described above, well 

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

 black streaks on the body ; a lateral series of 4 to 6 blue ocelli is 

 present iu 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 pinlc colour. 



The 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 Emmans, Enslin, and 

 Steynsbuvg in the Kimberley llusenm.
