216 Annals of the South African Museum. 



I have examined in addition 19 specimens preserved in the 

 South African Museum. Scales across the body 40 to 60 ; femoral 

 pores 12 to 16. One specimen, from Little Namaqualand, with a 

 single postnasal. 



The habitat of N. tessellata is a wide one, extending from Great 

 Namaqualand to the Karroo and Natal, and the species being also 

 on record from Mozambique (Berlin Museum) and the Zambesi 

 (Sir J. Kirk), it will probably be discovered in Southern Rhodesia. 



The species of Nucras appear to be of very local occurrence, and 

 much more collecting will have to be done before their distribution 

 can be properly mapped out. It is hoped that this contribution to 

 the knowledge of them may be an incentive to the collecting and study 

 of further material.
