In the accompanying files, where itineraries and maps are available they are given. Praeger did not conduct the same methodical fieldwork in all Irish counties, and his itineraries only cover those vice-counties asterisked (*) below. For a number of vice-counties the maps are missing (), and in these and other cases, unmarked Philips maps are provided, since these supply valuable locality information used by field workers at the turn of the century.
