The priiici])al general lists of Greater Antillean spiders are 1)y Xatlian 

 Banks, who has reported on collections from Cuba (1909), Haiti (1903) 

 and Porto Eieo (1902). Practically the only list for the Lesser Antilles 

 is Eugene Simon's for St. Vincent. Except for Banks's Cuban list, whicli

 with the ideas of Mr. Banks, who is responsible for the identification of 

 most of our specimens. Unless otherwise stated, I have also relied on 

 Petrunkevitch's catalogue for data concerning distribution in the western 

 liemisphere. I have usually departed from the alphabetical arrangement 

 of genera used Ijy Petrunkevitch and followed more nearly the arrange-
