Comments. — Earlier records of Hemorrhois algirus were somet im es attributed to Coluber 
florulentus, of which algirus has sometimes been considered a subspecies (e.g., Kramer and 
Schnurrenberger 1959,1963). Wemer (1909) reexamined older records and clarified that the Sokna 
record of Zamenis florulentus of Peters (1880, 1881) was referable to this species. He also identi¬ 
fied the “Benghasi” record of von Martens (1883) (now ZMB 10506) as Zamenis gemonensis (now 
Hierophis gemonensis ), perhaps collected in Europe en route to Libya and subsequently confused 
with the Cyrenaican collections made on the same trip. Schatti (2004) reidentified the single Platy- 
ceps rogersi recorded by Schleich (1987) from Kouf National Park as H. algirus. [Note that Schle¬ 
ich (1987) listed specimens KNP 1981/272, 311, 354, and 509 as both Coluber algirus and Naja 
haje. We have assumed that the associated localities are correct for both species and that specimen 
numbers were inadvertently duplicated].
