Family 2. Architarbid^. 



Genus Geraphrynus, Scudder : G. carbonarius, Scudder. 



Genus Geratarbus, nov. : G. lacoei • scabrwm, spp. u. 



Genus Architarbus, Scudder : A. rotundatum, Scudder ; elongatum, sp. n. 



Genus Kustarachne, nov. : K. tenuipes, sp n.

 Order PEDIPALPI. 



Family Geralinukid^. 



Genus Graeophonus, nov. : G. carbonarius, sp. n. 



Genus Geralinura, Scudder : G. carbonaria, Scudder. 



Observations. — In these classifications the order Anthracomarti contains hetero- 

 geneous elements belonging to the orders Aranea3 (Arthrolycosa), Ricimdei (Polio- 

 chera), Anthracomarti {Anthracomartus), and, in my opinion, Phalangiotarbi 

 {Geraphrynus, Geratarbus, Architarbus) . 



In the Pedipalpi the genera referred to the family Geralinuridas belong to the 

 very distinct sub-orders Amblypygi {Grseophouus) and Uropygi {Geralinura).
