A REVISION OF THE PISAURIDAE OF THE UNITED STATES 23 
Cephalothorax slightly longer than broad, constricted in front of 
cervical grooves. Eyes in two rows (pl. 9, fig. 4); anterior slightly 
procurved, posterior strongly recurved; median ocular area as wide, 
or slightly wider posteriorly than long; eyes of the anterior row 
equal in size and equidistant. Lower margin of furrow of chelicera 
with three teeth (pl. 9, fig. 3). Abdomen about twice as long as 
broad. Legs: First, second and fourth longest, about equal; third 
shortest; tibiae and metatarsi of first and second legs beneath, with

Type: Dolomedes mirus Walckenaer; type specimen not known to 
exist 
Type locality: Georgia 
Female: Length 13-16.5mm; average of ten, 14.4mm; legs 1-2-4 about 
equal, third shortest; pl. 5, fig. 1; pl. 8, fig. 3; pl. 9, figs. 2-5; pl. 11 
Cephalothorax above with ground color light yellow to light brown 
on the sides and with a median band, dark brown, tapering slightly 
from clypeus to posterior margin of cephalothorax; median band 
inclosing the eyes and occupying about one-third of the entire width 
of the thorax; extreme margin of thorax often with a narrow, 
dark line; sides diffused with dusky; bordering the median band, 
often a line of white hairs; the median band clothed with brown 
hairs and in the eye region, long, white ones. In life or dry, the 
sides appear covered with dirty white hairs and the color of the 
integument is obscured. Eyes surrounded with black (pl. o, fig. 4); 
eyes of anterior row in a slightly procurved line, practically esual in 
size and equi-distant, separated by a little less than the diameter of one 
of them; posterior row strongly recurved, eyes equal in size and 
larger than those of anterior row; median separated by the diameter
