In the two smallest specimens (N:o 5 and 6) the usual 

 dark markings on the head and the dark dorsal stripe are ver}' 

 indistinct, especially in N:o 5 in which there appears only a 

 faint indication of the narrow light line which is usually to be 

 seen in the dark vertebral band. The natives call this snake 

 »ombimati» (signifying killed ox or flesh of ox) on account of 

 its red ground-coulour. It is seen everywhere, sometimes clim- 

 bing in the bushes.
