Absolutely disgusting creatures in this one. Myriapods, do I need to say more?! Come and meet the house centipede and the scolopenders! There are apparently 111 (!) species of myriapods in the Nordic countries, all of them covered in this tome. The volume also includes a general introduction to Arthropoda, since “Nationalnyckeln” is eventually supposed to cover all species of this obnoxious phylum (around New Year Day 2050, presumably).
