retinal rods ; is, in fact, a laminated part of the cuticle filling 

 the small retinal cup. 



Beddard would interpret this eye as Carriere has done that 

 of Nereis, thinking that separate minute pigment cells might 

 be found in the pigmented zone of the retina. 



Phyllodocid^. 



Eulalia annulata Verrill ? 



The two large eyes look upward and outward and are buried 

 beneath the surface. The retinal cells when isolated have much 

 the form of those found in Lepidonotus (Fig. 51), but the pig- 

 ment in them is red, not black. In section (Fig. 31) the retina 

 is buried in the brain, but sharply marked off from it and from 

 the epidermis also, except at one point ; here the retina and 

 epidermis are continuous. The cuticle penetrates this region 

 as a slender stalk continuous with the lens. 



The lens is much shrunken both by Perenyi's liquid and by 

 chromic acid, and presents an unusual appearance, being a mass 

 of darkly staining round granules. How far this is merely arti- 

 ficial could not be determined from the material at command, 



Ejilalia pistacia Verrill. 



The eyes here differ in not being as far removed from the 

 surface as in the preceding species, and in having a stouter con- 

 nection with the cuticle. The lens seems to extend out to the 

 cuticle without a very marked stalk ; but it is poorly preserved, 

 presenting the appearance of a reticulated coagulum containing 

 some dark granules seen in the other species. 



The dark red, retinal pigment is in strong contrast to the 

 brightly refracting green-yellow spherules found, in this species, 

 aggregated in the cuticular ends of the ordinary epidermal cells. 



Phyllodoce catenula Verrill. 



Here again we find the same structure ; the retinal cells are 

 longer and the lens comes into direct contact with the cuticle, 

 presenting also the finely granular appearance of a coagulated 

 liquid mass. 



Some imperfect observations upon Anaitis picta Verrill indi- 

 cate that here again the eyes are much as in Phyllodoce.
