Figure 19. — Paratfiis ociilatiis n. sp. Specimen No. 118. Eyes, x 70. 



The only really well preserved organs are the eyes (textfigurc 

 ig). They are eight in number and apparently only the right 

 anterior lateral eye is completely indiscernible. Of the right 

 anterior median eye a part of the outline is preserved and the 

 remaining eyes are clearly visi1)le. The anterior row is slightly 

 procurved and much longer than the strongly recurved posterior 

 row. The anterior median eyes are the largest and are about 1.75 

 their diameter apart. The anterior lateral eyes are also large, 

 but distinctly smaller than the anterior median eyes and are sepa- 

 rated from the latter by 1.50 their diameter. The eyes of the 

 second row are considerably smaller, their diameter being about 

 3.50 times smaller than the diameter of the anterior median eyes. 

 All eyes of the second row are of the same size. The posterior 

 median eyes are situated between and slightly behind the anterior 

 median eyes, are twice their diameter apart from each other and 

 about one diameter from the respective anterior median eye. The 

 posterior lateral eyes are behind and to the outside of the anterior 

 median eyes from which they are removed by three diameters, 

 while the distance between the posterior lateral and posterior 

 median eyes is about six of their diameters. This arrangement of 

 the eyes agrees closely with the description given In- Scudder for 

 Parattus resiirreefits and is the reason why I have placed the 

 otherwise so poorly preserved specimen without hesitation under 

 the genus Parattus.
