is of a yellowish-grey hue with some reddish hairs intermixed, 
and has three brown bands in the middle, which unite in a 
point near the spinners. 
An adult and an immature male of this Salticus were taken 
in the Island of Bermuda. 
Family THOMISID&. 
Genus THomisus, Walck. 
Thomisus pallens, n. sp. 
Length of an immature female ~ of an inch; length of 
the cephalothorax =, breadth +5; breadth of the abdomen +5 ; 
length of an anterior leg 2; length of a leg of the third pair 4. 
The cephalothorax is slightly compressed before, truncated 
in front, rounded on the sides, depressed at the base, convex, 
and glossy ; the falces are subconical and vertical ; the maxille 
are convex near the base, obliquely truncated at the extremity, 
on the outer side, and inclined towards the lip, which is tri- 
angular; the sternum is heart-shaped; the legs are glossy, 
sparingly supplied with hairs, and have two parallel rows of 
spines on the inferior surface of the tibiz and metatarsi of the 
first and second pairs, which are much longer than the third 
and fourth pairs; the first pair slightly surpasses the second, 
and the third pair is the shortest; each tarsus is terminated 
by two curved, pectinated claws ; the palpi are short, and have 
a small, curved, pectinated claw at their extremity. These 
parts have a pale dull-yellowish hue, the lateral margins of 
the cephalothorax being the palest. The eyes, which are 
dark-coloured, are disposed on the anterior part of the cephalo- 
thorax in two transverse curved rows, forming a crescent 
whose convexity is directed forwards; the four intermediate 
ones describe a square; and the eyes of each lateral pair are 
seated obliquely on a conspicuous pale tubercle, the anterior 
one being the largest of the eight. The abdomen is oviform, 
somewhat depressed, thinly clothed with short hairs, and pro- 
jects over the base of the cephalothorax; on the anterior half 
of the upper part there are five depressed spots, which de- 
scribe a narrow, elongated angle whose vertex is directed for- 
wards ; its colour is yellowish-white, the upper part being the 
palest. 
An immature female of this spider was captured in the 
Tsland of Bermuda.
