Taxonomic and distributional notes: 
Psammophis sibilans var. stenocephalus 
Boeage 1887, was was synonymized with 
Psammophis notostictus Peters, 1867 by 
Boulenger (1895a). Psammophis notostictus 
was described as a variety of Psammophis 
moniliger (Daudin, 1803) by Peters (1867a) but was also treated as a variety of P. sibilans 
(Linnaeus, 1758) by several authors (see Broadley 1975b). Boeage (1895a) referred to P. sibilans 
var. B, but in the same account equated this with his P. s. var. stenocephalus Boeage, 1887. 
Boulenger (1896) treated P. notostictus as a full species, and was followed by several authors until 
Loveridge (1940) again considered it as a subspecies of P sibilans. Mertens (1955) restored 
notostictus to its current specific rank.
