Salticides. — Eyes 8, exceedingly unequal in size, in 3 transverse 

 rows, 4.2.2., or forming a large quadrangular 

 figure, and occupying the greater part of the 

 top of the caput. The central pair of the 

 anterior row are always largest, and those 

 of the middle row the smallest. 



Spinners 6. 



Legs moderately long, often greatly differing 

 in strength ; terminal tarsal claws 2. 



Caput almost always as broad as the thorax, 

 and without any lateral marginal constric- 

 tion. 



These are spiders which, with a few exceptions, 

 are noted for their leaping habits. The 

 large quadrate cophalo-thorax gives a 

 general form not easily mistaken, although 

 in respect to robustness there is immense 

 variation in the different groups. They 

 spin no snare, though they frequently form 

 silken nests of a tubular and other kinds.
