4 TERRESTRIAL CARBONIFEROUS ARACHNIDA. 



Observations. — Protolycosa is very likely correctly referred to the Liphistiida?. 

 Kreischeria does not belong to the Trogulida? of the order Opiliones, but is closely 

 related to Eophri/nus. The order Anthracomarti contains the elements of two 

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

 Architarbidfe, with Architarbus, should be eliminated from the Anthracomarti, and 

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

 Eophrynidse.
