4 TERRESTRIAL CARBONIFEROUS ARACHNIDA. 



Observations. — Proiohjcosa is very likely correctly referred to the Lipliistiidse. 

 Kreischeriu does not belong to the Trogulidiie of the order Opiliones, but is closely 

 related to Eophrijnns. The order Anthracomarti contains the elements of two 

 orders ; and the Architarbidffi the elements of two distinct families. The 

 Architarbida?, with ArcJiitarbus, should be eliminated from the Anthracomarti, and 

 Atiihnicomartus left in the order as the type of a family — distinct from the 

 Eophrynidse.
