Dear Barry,

That's what I would have thought - any dissenters?

By the way a search of the ICZN site for "spp" (with or without period) only turns up a few results, none of them definitive, but seemingly consistent in using the full stop:


And the BZN "Instructions to authors" has "pp." as the abbreviation for pages (with full stop), similarly "pls." for plates (though no "spp")...


Regards - Tony
