by Abbot.' Walckenaer’s description of the species follows: 
“Abdomen en ovale allongé fauve, a dos blanc sur ses cotés, et au 
milieu seize points d’un blanc-bleuatre clair, six de chaque cote 
disposés longitudinalement, et quatre plus petits placés sur deux 
lignes transversales au-dessus de l’anus. Corselet allonge fauve, 
borde d’une raie branche sur les cotés. Pattes fauves mouchetées 
de taches plus foncées.”’ 
The description fits Abbot’s figure except that he mentions six- 
teen bluish white points instead of fourteen as indicated in the 
drawing. [vidence that Walckenaer had a specimen before him is 
also indicated by the fact that he gave the length as nine lignes 
whereas the drawing is considerably larger. This is Abbot’s “ water 
- spider’? and the following note accompanies the drawing: “ Taken 
June 4th. It makes no web and keeps on the water in ponds, springs 
and brooks, running on the water’as 1f on the ground. It retreats 
under logs, boards etc., preying on the insects it meets with, prin- 
cipally such as fall into it, not very common.”’ 
Specimens having the wide thoracic band I have found only in 
collections from Georgia, chiefly from various localities in the 
Okefinokee swamp. Mature females were taken in June on Billy’s 
island; other specimens were taken from Minnie lake, Billy’s lake, 
and the surrounding cypress bays.

This subspecies, which is the familiar form in the north, also 
occurs in all the South Atlantic states and differs in the arrangement 
and extent of the color areas and in the smaller size of the males. 
In this species the light integument and white-haired submarginal 
band? of the cephalothorax is reduced to a line which is not continued 
across the clypeus; the white spots of the abdomen are usually ar- 
ranged in two rows of five or six each, the posterior ones becoming 
indistinct in old or rubbed specimens. The females may be as large 
as those of the typical form, but the males average but 9mm in 
length. A large male from Georgia measures 13mm. The structure 
of the palpi and epigyna in the two varieties affords no grounds for 
their separation as distinct species although there may be slight dif- 
ferences noted in the shape of the tibial apophyses. In young mature 
males from the north, there is a more or less prominent spur or 
blunt tooth at the base of the apophysis which is reduced in older 
specimens and lost in the southern form. Dolomedes sex-
