Fam. Salticides. 

 Genus Salticus, Bl. (Attus, Sim*, &c). 



Salticxjs inexcultus, sp. n. 



Adult male, length 2| lines. 



The cephalothorax of this species is massive and, looked at from 

 above, of a short, broad, oval form ; in profile the hinder slope is 

 very abrupt and a little hollow ' or impressed, the ocular region 

 sloping forwards and slightly prominent ; it is of a deep brown 

 colour, with a not very broad marginal band (running also round the 

 front) of white squamose hairs ; the upper surface of the caput is 

 thickly clothed with brightish and rather coppery-yellow, short, 

 adpressed, squamose hairs ; and these are continued in a tapering 

 form to the hinder slope, where they merge in a longitudinal central 

 band of white hairs ; the sides of the caput and thorax are thinly 

 clothed with dull coppery-yellow hairs ; and the upper surface, as 

 also the ocular area and clypeus, is furnished with longish promi- 

 nent bristles and strong hairs. 



The eyes are normal both in respect of position and relative size ; 

 the two forming the third or hinder row are rather wider apart than 

 the laterals of the first row, and the area enclosed by these four is 

 about double as long in its transverse as in its longitudinal diameter ; 

 the exact position of the two minute eyes forming the middle row 

 could not be ascertained, owing to their concealment by the hairs 

 around them. 



The legs are strong and moderately long ; their relative length 

 appeared to be 3, 1, 4, 2; they are of a dark brown colour (the 

 femora of the first pair of a red hue), furnished with hairs, bristles, 

 and spines, a few of the hairs being white and squamose ; the tarsi 

 of the second, third, and fourth pairs are of a pale yellowish colour, 

 banded with brown ; and each has a terminal tuft of hairs beneath 

 the tarsal claw. 



The palpi are short and rather slender, of a pale yellowish colour, 

 except the posterior halves of the humeral and the digital joint, 

 which are brown ; they are furnished with hairs and bristles : 

 numerous squamose white hairs are distributed over the upper sur- 

 face and sides of the humeral and cubital joints, and a few on the 

 radial ; this last is about equal in length to the cubital joint, and its 

 outer extremity is produced into a tapering, blackish, corneous, pointed 

 apophysis. The digital joint is equal in length to the radial and cubi- 

 tal together, and has numerous whitish hairs at its extremity. The 

 palpal organs are simple, not prominent nor highly developed ; a 

 slender filiform blackish spine issues from their base and curves 

 round their inner margin to their extremity. 



The falces are small, subconical, directed backwards, and of a 

 deep black-brown colour. 



The maxillce, labium, and sternum are normal in form, and of a 

 deep brown colour, tbe former tipped with a paler hue. 



The abdomen is small, oval, thickly clothed with hairs of a yellow- 

 ish grey, black, and coppery hue, forming a broadish roughly dentate
