row of eyes viewed from in front moderately procurved, a line tangent 

 to the lower edges of median eyes intersecting upper border of lateral 

 eyes; viewed from above a line tangent to the anterior edges of median 

 eyes passes near middle of surface of laterals. Anterior median eyes 

 with diameter smaller than that of the laterals in ratio 3:4; not quite 

 two thirds their diameter apart, less than their radius from the lateral 

 eyes. Posterior lateral eyes smaller than the anterior laterals, their 

 diameters comparing as 13: 16; about their rachus from the anterior 

 ones. Posterior median eyes very much, smaller than the laterals, 

 the diameters being as S: 13; somewhat nearer lateral eyes than to 

 the anterior medians; but little elongate, somewhat obliquely trun- 

 cate caudad. A line tangent to caudal edges of the two posterior 

 eyes one each side intersecting the anterior median eye of the opposite 

 side
