1752). Seba specimens are known or believed 
to be present in collections in St. Petersburg, 
London, Leiden (including specimens until 
recently in Amsterdam), Paris, Copenhagen, 
Stockholm, Bremen and Berlin (Boeseman 
1970; Juriev 1981; Thireau et al. 1998; Bauer 
and Gunther 2013) but few can be traced to 
particular plate figures, and the lectotype of 
Matrix lubrica is not among these. Wallach et 
al. (2014) cited no source for the designation of 
a lectotype, and indeed, no lectotype seems to 
have been formally designated previously, 
although most authors have only cited the 
African syntype (or Seba’s figure) as type 
material, apparently unaware that the original 
description was based on more than one speci¬ 
men. We interpret Wallach et al.’s use of the 
term lectotype as an intended lectotype desig¬ 
nation, but as it lacks an express statement of 
deliberate designation (Art. 74.7.3) this designation is not valid, although it is appropriate, as the 
other specimen(s) implied are apparently referable to some other taxon, presumably from South 
America. Broadley and Baldwin (2006) referred Aspidelaps lubricus infuscatus Mertens, 1954, 
which had generally been recognized as the taxon occurring in northern Namibia, to the synonomy 
of^. /. cowlesi.
