evidently a mistake. Linné himself considers his Acarus lomjiGornls 

 as a synonym to Géoffroy's Chelifer totiis ruber , antennis extremo 

 hlsetls. Schrank too considers his own species Acarm longicoruis 

 as a synonym lo Géoffroy's Chelifer. Both Linné and Schrank 

 cite GEOFFROY'. If we now compare Géoffoy's figure with those 

 of Hermann we see at a glance that Géoffroy's Chelifer is nothing- 

 else but Hermann's Seines louglrostrls (tab. 6, f. 12, and tab. o. 

 f. 13). Even Hermann seems to have been aware of this supposition , 

 for be calls his Semis longlrostris in his Explicatie ta])ulaium , p. 140 . 

 Scirus longicoruis.
