white colour, with the exception of the axillary joint and the 

 erreater part of the humeral joint, which have a brown hue. 

 The abdomen is oviform, convex above, and projects over the 

 base of the cephalothorax ; it is of a dark-brown colour, and has 

 a large, dull, yellowish-white spot on each side of the medial 

 line of the upper part, near its middle ; some scale-like hairs, 

 that reflect prismatic colours, are distributed on the under part; 

 and the spinners have a brownish-yellow hue. 



An immature female of this Salticus was the only specimen 

 of the species included in the collection. 



Salticus candidus, n. sp.

 cephalothorax -j^, breadth ^; breadth of the abdomen -^;

The cephalothorax is large, glossy, somewhat quadrilateral, 

 abruptly sloped at the base, and advanced a little beyond the 

 falces in front ; it is of a pale-yellow colour ; the entire region 

 of the eyes and a large spot on each side of its base have a black 

 hue, and the sides are sparingly supplied with scale-like hairs 

 that reflect brilliant prismatic colours. The very minute inter- 

 mediate eye of each lateral row is nearly equidistant from the 

 eyes constituting its extremities. The falces are small, sub- 

 conical, vertical, and of a pale-yellow hue, with an oblong, soot- 

 coloured spot at their base, in front. The maxillae are short, 

 straight, and enlarged and rounded at the extremity; and the 

 lip and sternum are oval. These parts have a pale-yellowish 

 hue, the sternum being the palest, and the lip having a tinge of 

 brown at its base. The legs are provided with hairs and a few 

 fine spines, and are of a yellowish-white colour, with a small 

 black spot at the extremity of the femur of each posterior leg, 

 on the inner side; the fourth pair is the longest, then the third, 

 and the second pair is the shortest ; each tarsus is terminated 

 by two curved, pectinated claws, and below them a small scopula 

 is situated. The palpi resemble the legs in colour, and the 

 development of the digital joint is such as merely to suffice for 

 the determination of the sex. The abdomen is oviform, glossy, 

 convex above, and projects over the base of the cephalothorax; 

 it is of a yellowish-white hue, with a soot-coloured mark on 

 each side of its anterior extremity, from which a short longitu- 

 dinal streak of the same hue passes to the sides ; the upper part 

 is crossed by two somewhat irregular, curved, black bands, 

 the anterior one is the broader, and their convexity is directed 

 forwards ; a circular black spot, situated immediately above the 

 spinners, comprises two very minute white specks placed trans- 

 versely ; and the sides, like those of the cephalothorax, are
