Volume 32 Part 2 (2004) 199—203
Owing to a problem at the printing stage, Figure 1 on page 200 did not appear at a sufficiently high resolution to enable the double lines of both the inner and the outer membrane of the Ignicoccus cells to be clearly visible. The Figure is reprinted here for this purpose, together with the associated legend.
