In the above paper by Nestola et al., published in the December 2009 issue of Mineralogical Magazine, a mineral was incorrectly named. All references, including that in Fig. 1, to jordanite (Pb14As6S23), should be replaced by sartorite (PbAs2S4).

Under the heading of Occurrence, the authors also wish to point out that the sample containing dalnegroite was provided by Luca De Battisti, a mineral collector, who collected the sample at the Lengenbach quarry in the summer of 2006.
