Several Arachnida allied to Eophrynus prestvicii have been discovered in beds of Carboniferous age. Of these the only species known to me as belonging unquestionably to the genus Eophrynus that has been properly described and figured is the form from Silesia named Eophrynus (in error written Euphrynus) salmi by Stur. The type is 27 mm. in total length, the prosoma being 8 long and the opisthosoma 19 long and 14 wide. The last-named region is thus considerably narrower in relation to its length than it is in E. prestvicii. Apart from this, it is noticeable that the admedian dorsal tubercles, except on the second and third terga, are much smaller than the laterals.
