PREFACE. Vll 



pencil farther illustrate the subject. These notes have been 

 printed in smaller type and, with Mr. Emerton's initials, in- 

 closed in brackets. The Society is also indebted to Mr. Wm. 

 E. Holden, of Marietta, Ohio, for some additional notes to 

 which his name is appended. 



The proportion of species identified by Mr. Emerton is, per- 

 haps, small, a fact not to be wondered at when we consider how 

 many Southern forms were described by Hentz, for the recog- 

 nition of which, extensive collecting in the South is necessary. 

 Among the species identified, a number have proved identical 

 witli European forms, and Hentz's names must yield to those 

 longer established. 



To aid the student in referring to the original place of publi- 

 cation, the pagination of the latter has been inserted in black- 

 faced type in the text of the present work. For the same reason 

 the original numbers remain on the plates, although these are 

 now referred to by new numbers for the sake of convenience. 

 As the stones from which the lithographic plates were taken 

 were destroyed, and as unfortunately several of the copper 

 plates are also missing, it has been necessary to reproduce 

 nearly half of the plates in this edition by some method of 

 photography, a work which has been entrusted to Mr. E. Bier- 

 stadt, of New York. Although the Alberttype plates by no 

 means equal the originals either in beauty or in clearness, it is 

 hoped that most of the figures will be recognizable without 

 difficulty. 



After Hentz's death his collection of spiders came into the 

 hands of the Society, but has long since been almost entirely 

 destroyed. The remains now consist of portions of sixty 

 specimens gummed on cards, and of these, only twenty-seven
