. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. 9. Outline drawings of ganglia and eyes of salpa. a. — anterior ; d. — dorsal ; Gg. = ganglion ; />. = posterior ; r'. = ventral ; x. indicates in each case the same region of the eye. FIG. A. Dorsal view of ganglion and eye of a solitary salpa. The horseshoe- shaped eye is above the ganglion, with the ends of the horseshoe pointing forward. FIG. 1). The same seen from the right side. FIG. C. Ganglion and eye of an immature chain Cyclosalpa pinnata. In an earlier condition this eye was horseshoe-shaped and lay horizontally on the dorsal surface of the ganglion, resemblimg Figs. A and B. It has now rotated forward and upward through an arc of about 90°. That surface of the eye which was dorsal when the eye was horizontal is now anterior. FIG. D. The same eye and ganglion as those shown in Fig. C., but here seen from behind. The eye is in the form of a flat plate, ihe hollow of the horseshoe having become filled with cells. FIG. E. The eye and ganglion of an adult, chain Cyclosalpa pinnata, seen from the right side. The eye has shifted 90° still further forward and is again horizontal, but with its former posterior portion now anterior. (Cf. Plate VII., Fig. 3. ) FIG. F. Dorsal view of the same eye and ganglion as those shown in Fig. E. The eye is seen to be split posteriorly into two limbs, being again horseshoe-shaped. (Cf. Plate VII., Fig. 4.).
