large que la ligne intermediate.” And on page 344 we read: “Pirates. . . . 
se rapprochent deja du genre Dolomede.” The name of “ waterspider’’ 
given to the species by Abbot and his additional observations on the aquatic 
habits of the spider establish beyond doubt the identity of tritoti with 
sexpunctatus Hentz, which latter becomes therefore a synonym of the 
former.

to give me, together with his entire collection of Brazilian spiders.

Lower margin (retromargin — A.P.) of fang groove with 4 large, equally strong 
and equidistant teeth; upper margin with 3 teeth of which the middle is the largest; 
second row of eyes slightly proeurved by their lower margin: the laterals oval, 
much smaller and equally removed from the median and the posterior eyes; the 
medians are removed by their radius from each other and from the laterals, and a 
little closer to the slightly smaller ones of the anterior row; quadrangle a little 
longer than broad, scarcely narrower in front; elypeus about twice the diameter 
of the anterior eyes; eephalothorax high, steep behind, straight to posterior row of 
eyes, from this point on slightly inclined; sides of head sloping, but steeper than sides 
of thorax: median groove deep anteriorly, scarcely visible posteriorly; head and 
radiating grooves not distinct: mandibles very strong; lip scarcely longer than 
broad in front, narrower toward base, its tip truncate, a transverse impression near 
middle; maxilloe arched, broader toward end. their outer edge straight, while their 
inner edge is strongly emarginate around lip; spinnerets short, the posterior pair 
more slender and a little longer; terminal joint short: legs very strong; tarsi and 
metatarsi with thick scopula?. 
Color: Entire animal tan colored; abdomen a little darker above and on sides; 
tarsi and metatarsi darker; mandibles dark reddish brown: lip and maxillse a little 
lighter, with a still lighter edge: integuments covered with golden yellow hair; longer 
grayish hair on mouthparts. 
Spixes ox legs: First leg .— Femur, above. 1-1-1. in front. 2 distal ones, behind, 
1-1: tibia, below, 2-2-2-2: metatarsus, below, 2-2-2.
