This species is undoubtedly de Selys' P. praetextatum, the types of 

 which (from Zanzibar) were compared with our South African series. 

 Considerable uncertainty exists about the older names Kersteni and 

 Deckeni, both given by Gerstacker to specimens from the region of 

 Mombasa. It is possible that one or both of these names (absolute 

 priority would belong to the name Kersteni) apply to the species 

 here described ; but since no certainty could be reached, it was 

 thought preferable to adopt the name for which the types could be 

 examined.
