There is not the least reason to assume that the Arachnida were 

 better represented in the Carboniferous and the Permo-Carboniferous 

 of Bohemia than in any other Coal-areas of Europe and America; 

 it merely shows that more careful attention has been directed 

 towards the collecting of the fossil fauna of these beds there than 

 elsewhere, and that Dr. Fritsch has been more energetic in describing 

 them than the palasontologists of some other Coal-regions. Much 

 splendid work has, however, been done with the Insect fauna of 

 North America by S. H. Scudder and by the late lamented Charles 

 Brongniart in that of Commentry, France, as well as by the workers 

 in other countries, and we may look forward with confidence to great 

 accessions to our knowledge in this field of research as soon as the 

 splendid material obtainable becomes better known. 



Of the Bohemian specimens of special interest may be recorded 

 the remains of Artlirolycosa carbonaria, Kusta, from Rakonitz, a genus 

 also met with and described by Harger from the Coal-measures of 

 Illinois, U.S.A., of which good material for four other species have 

 likewise been obtained in Bohemia. It is extremely interesting to 

 record the discovery of a specimen of this genus, A. palaranea, Fr., 

 still attached to a leaf of Cordaites as in life. 



ProtoJycosa anthracophyla, described by F. Eoemer in 1866 from 

 the Coal-measures of Silesia, is also reproduced with care.
