Map of the Slavic Villages in Epirus, Thessaly, Halkidiki -1800s

The only relevant information I found about his work was that his ethnographic map of slavic peoples was made in 1874 in St. Petersburg instead of 1885 Warsaw.

Is there a higher definition version of this map and source would be great.

Do you have a reference for what values each colour represents?

A detailed map published in Warsaw by a Russian ethnographer (Александр Фёдорович Риттих) in 1885 showing the Slavic population of the Balkans. This map was a product of many years of research he conducted during the 1800s. You can see the villages in Epirus, Thessaly, and Halkidiki where he found elderly people who still had knowledge of their native Slavic dialects. By 1900 they were completely lost and assimilated by the surrounding populations.
