PREFACE 



All of the types of the new species described in this paper are in the col- 

 lection of the author. Paratypes are to be distributed in those species described 

 on a large series. Eventually the author's collection of pselaphidae will be 

 deposited in a museum. 



Twenty-one plates are included to illustrate pselaphid anatomy and 

 taxonomy. These have been drawn by the author. Although great care has 

 been exercised, some discrepancies may be found between a given figure and 

 the text. In all such cases the text is to be considered correct since the curva- 

 tures of parts makes the exact delineation difficult, or exact drawing may dis- 

 tort habitus. Where discrepancies exist between halves of a bilaterally sym- 

 metrical figure, the left side is to be considered in preference to the right side.
