organs, which are moderately developed, with a slender, curved, 

 reddish brown spine near the extremity, on the outer side, and 

 are of a yellowish-red colour. The abdomen is oviform, clothed 

 with hairs, somew'hat depressed, and projects over the base of 

 the cephalothorax ; the vipper part is of a yellowish-brown co- 

 lour, with a series of yellowish-white angular lines in the middle, 

 whose vertices are directed forwards ; three dark-brown spots 

 occur on each side of the medial line, and above the prominent 

 yellowish-red spinners there is a yellowish-white space, which 

 comprises two contiguous, brown, angular lines; the upper part 

 is encompassed by a white band, and the sides and under part 

 have a dark-brown hue, a dull-yellow band extending along 

 each side of the latter. 



This Salticus was captured in the island of Madeira.

The cephalothorax is glossy, somewhat quadrilateral, and 

 slopes from the posterior eyes to both extremities ; it projects a 

 little beyond the falces in front, has a broad, shallow indenta- 

 tion in the middle, and is of a brown colour, the medial line 

 and the sides, which are much the palest, having a tinge of red; 

 and the hue of the cephalic region and narrow lateral margins 

 is brownish -black. The minute intermediate eye of each lateral 

 row is rather nearer to the posterior than to the anterior eye of 

 the same row. The falces are short, subconical, and vertical ; 

 the maxillge are straight, and enlarged and rounded at the ex- 

 tremity ; and the lip and sternum are oval. These parts are of 

 a red-brown colour, the falces being the darkest, the maxillae 

 uuich the palest, aud the base of the lip having a dark-brown 

 hue. The legs are moderately robust, and are ])rovided with 

 hairs and sessile spines, two parallel rows of the latter occurring 

 on the inferior surface of the tibire and metatarsi of the first 

 and second pairs ; they are of a dull-yellow colour, with a red- 

 brown annulus at the base of the tibife, metatarsi, and tarsi; 

 the fourth pair is the longest, then the third, and the second 

 pair is the shortest; each tarsus is terminated by two slender, 

 curved claws, and below them there is a small scopula. The 

 palpi are short, and have a pale-yellowish hue. The abdomen 

 is oviform, thinly clothed with hairs, convex above, and projects 

 over the base of the cephalothorax ; it is of a yellowish-white 

 colour, the under part being the palest ; the sides are irregularly 

 marked with brown intermixed with yellowish-white; a broad 

 yellowish-white band, which extends along the middle of the
