Moreover, the duct invariably keeps ahead of the progress of segmentation backwards. an. pr. d. ntcd. sp. cd. som. I. p.. spl. I. p. end. Fig. IV.

Distribution. —The giant ganglion cells of Ctenolabrus form a single median longitudinal row in the dorsal portion of the cord (Fig. 1). They lie within the dorsal fissure, their upper surfaces being on a level with the dorsal limit of the cord, and are covered by the membrana prima (Fig. 3). Each cell is surrounded by a capsule formed of three parts: 1) the membrana prima, which is arched above each cell (Figs. 3 and 5, mb. pr.); 2) the neuroglia fibres (fbr. n'gl), which come oft from this membrana
