The figures which follow are copies made from Abbot’s manuscript drawings, upon 
which Baron Walckenaer based his descriptions of many American spiders, 
and on the authority of which I have changed the accepted nomenclature of a 
number of species. (See page 133 of this volume.) I give a few examples here 
in order that students who cannot consult the manuscripts in the Kensington 
(London) Museum may judge for themselves as to the correctness of my decis- 
ion. The numbers attached are those of Abbot’s figures.
