Posterior row of eyes strongly recurved; medians their radius apart, 

 two and a fourth or more times their diameter from the laterals. 

 Lateral eyes nearly contiguous, the anterior one the larger, elevated 

 on a low common tubercle. Area of median eyes wider than long in 

 about ratio 25 : 22 and wider in front than behind in about ratio 5 : 4. 

 Anterior row of eyes distinctly recurved; median eyes larger than the 

 posterior medians (diameters as 5:4), three fifths their diameter apart 

 and not fully their diameter from the laterals.
