 the former one with eyes largest of all and about their 

 radius apart. Posterior lateral eyes separated from central 

 ones by a distance about 1 V^ the diameter of the former. 

 Posterior eyes form an area, that is much broader than long

 meter of anterior lateral eyes and distance from them to 

 eyes of second row not fully as long. .
