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^e. 



Genus Thomisus, Walck. 



Thomisus pallens^ n. sp. 



Length of an immature female -^ of an inch ; length of 

 the cephalo thorax xV? breadth -V ; breadth of the abdomen -'-5- ; 

 length of an anterior leg -f- ; length of a leg of the third pair -^. 



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 maxillae 

 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 tibige 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 

 Island of Bermuda.
