_ The writings of these pioneers were unknown to Say, who pub- 
lished in 1821 a paper on the lower Arachnida, describing twenty- 
four species of Acarina and eight species of Arthrogastra. As 
we have already published elsewhere bibliographic lists of these 
two groups,’ we shall confine the account here given of the 
literature to the true spiders (Araneæ). 
The work of Baron Walckenaer has been mentioned already 
in connection with that of Bosc and Abbot. In the first two 
volumes of “Apteres” he described two hundred and forty-four 
orth American species, of which two hundred and twenty-six 
_ Were from Georgia and Carolina. Of these, one hundred and 
_ Seventy, over two-thirds, are distributed among the four genera,— 
Lycosa, twenty; Attus, sixty-six; Thomisus, twenty-seven; and 
Epeira, fifty-seven. 
Nicholas Hentz began his study of the spiders of the Southern 
States in 1821, and his publications in the Journal of the Boston 
Society of Natural History from 1842 to 1850 form the basis of 
the study of arachnology in this country. These papers, with 
one by the same author, have since been reprinted in the 
‘Occasional Papers” of the Boston Society (1875). Hentz de- 
_ Sctibed two hundred and fifty species, of which one hundred 
and ninety-nine, or four-fifths, were from the Southern States, 
Chiefly North Carolina and Alabama, where he resided for a 
me time. Of these, one hundred and fifty have not yet been 
\dentified by recent investigators. Add to this number those 
: described by Walckenaer, and we have from the Southern States 
lone a total of three hundred and seventy-five species of spi- 
ders which stand as mere names on our lists, with no specimens 
here to represent them! As Hentz nowhere mentions 
rkenaer's « Apteres,” it is more than probable that he was
