POTTHOFF: DEVELOPMENT AND STRUCTURE OF FINS IN CORYPHAENA 



Figure 8. — Posteriormost dorsal fin pterygiophore with its secondarily and serially associated rays from a 230 mm SL Coryphaena 

 equiselis. Left: anterodorsal view, secondarily associated ray has been moved to the right of the proximal radial; right: left lateral view, 

 pterygiophore has been tilted 30° from the horizontal toward the vertical. Symbols: Dj, distal radial of secondarily associated ray; 

 D, distal radial of serially associated double ray; P, proximal radial; Rj, secondarily associated ray; R, serially associated double ray. 

 Stippled, cartilage; darkened, bone.

Figure 9, — Anterior and right lateral views of right side of a disarticulated posteriormost double dorsal fin ray with its distal radial 

 from a 230 mm SL Coryphaena equiselis. a, right half of anterior ray, anterior view; b, right half of posterior ray and right half of its 

 distal radial, anterior view; c, right half of anterior ray, lateral view; d, right half of posterior ray and right half of its distal radial, 

 lateral view. Symbol; D, distal radial.
