Chamberlin.— PSEUDoscoRPiüNS from chilk and Sumatra 187 



1906 — Clitlionius curvidigitatus Simón, With Kgl. 

 Dansk. Vid. Selsk. Skrifter 1. Raekke III: 74. 



1911. — CJitJionius curvidigitatus Simou, Ellingsen, 

 Ann. Mus. Civ. Stor. nat. Genova 45: 36. 



Remarks. — As noted by both With and Ellingsn this 

 species liad to receive a uew ñame since curvidigitatus had 

 already béen used by Balzan for a South American species 

 as early as 1890; some nine years earlier thaii Simón des- 

 cribed this species from Sumatra under the same ñame. 



As With States, this species is remarkable in a num- 

 her of respects and will possibly ha ve to be referred to 

 another genus. This can be done safely, however only 

 upon a critical study of actual material of the species.
