row of eyes viewed from in front moderately proeiirved, 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

 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 radius from the anterior 

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

 the diameters being as 8: 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
