 when it is only a quarter of this size (fig. 220). The head is 

 narrower than in O. salticus, and the lateral eyes so high that 

 they appear to belong to the upper rather than the middle 

 row. The abdomen is the same width as the back part of the 

 cephalothorax and tapers a little toward the spinnerets. The 

 first pair of legs is longest and the second next. The general 

 color is green, with the space between the eyes red, red spots 

 and black spines on the legs, and two rows of red spots on the 

 abdomen, sometimes united into a stripe, with pairs of white 

 spots surrounded by red.
