FIGURES 92–118. Navicula romanedwardii sp. nov. and Navicula seibigiana s.s. LM & SEM pictures of Navicula romanedwardii taken from the holotype population (sample D18) from James Ross Island and two other populations on James Ross Island and South Shetland Islands (indicated below). LM pictures of Navicula seibigiana taken from the type slide (Praep. Hintz 160, Eu-CH 15 in Coll. LangeBertalot). 92–98. Navicula romanedwardii, LM views of 7 valves from the type population.
