Re- maining spines slightly decreasing in size towards the apex. Sulcus unforked, running directly to the apex. In the specimen from Lake Rukwa, Tanzania (ZMUC R631233) the right hemipenis was everted after fixation. The somewhat wrin- kled, hardened and incompletely distended organ bears scarcely detectable, slightly enlarged spines on the lower truncus. In this specimen the sulcus is unforked, running directly to the apex, ending in a terminal extension. Tip of apex calyculate. In contrast, in the incompletely everted hemipenes of the two speci- mens of Crotaphopeltis degeni from Sudan (RMNH 24411, 25018) the lower truncus bears a ring of several distinctly enlarged spines. In the uneverted hemipenes of specimens from Ethiopia (USNM 24389), Uganda (BMNH ) and Cameroon (RGMC 73-15- R209) clearly enlarged lower truncal spines are discernible. Crotaphopeltis hippocrepis (Fig. 4). In situ the hemipenes extend to subcaudal scute no. 8-12(x= , n = 38) (Rasmussen etal, 2000). Pedicel covered with tiny spines except for a longitudinal depres- sion on the asulcate surface. Lower truncus with two distinctly fe,.
