Remarks. Simon* properly characterized this genus under the 
name Thanatidius but selected as the type, Thomisus dubius 
Hentz. It is evident, therefore, that Simon had before him a 
specimen of the earlier described Tetragonophthalma 
undulata of Keyserling when he gave his diagnosis. 
Habits. Specimens from the Okefinokee swamp in Georgia were 
collected in the low ground bordering the islands. A mature male 
was taken in May 1912 and a mature female in June of the same 
year. 
Distribution. “Denmark, 5S. C.; *Billy’s island, Okefinokee 
swamp, *Waycross and *Fargo, Ga.; Punta Gorda, *Miami, Archer, 
Fla.; Mensura and Shreveport, La.; Havana, Cuba. 
PISAURINA Simon 
Hist. Nat. Araignées, 1898, 2:205 
The genus Pisaurina, proposed by Simon to include Dol o- 
medes mirus Walckenaer (type), and those species of Hentz 
described under the name Micrommata (M. undata, M. ser- 
rata, M. carolinensis ), was characterized as follows: an- 
terior row of eyes in a slightly procurved line, median larger than 
lateral; median ocular area slightly longer than broad posteriorly; 
posterior median somewhat larger than anterior median. Careful 
measurements of a considerable number of individuals of both sexes, 
however, show the median ocular area is as wide posteriorly (a 
little wider in some) as long, and that the eyes of the anterior 
row are equal in size and equidistant.
