NERVOUS SYSTEM IN GONIONEMA MURBACHII. 45 



tween the radial nerves, the cells lie radially closer, sending some 

 of their fibers up to the gelatinous layer. This net-work thus 

 serves as a connecting link between the radial and marginal nervous 

 structures. The manubrium also has its network of cells and 

 fibers and along the margin of the manubrium is a row of large 

 multipolar cells (Fig. 3, v) that send fibers to the periphery where 

 they join special sensory cells that lie among the epithelial cells 

 (Fig. 3, r~). In the radial region of the manubrium are larger 

 closely set nerve cells. It was seen that fibers from the nerve 

 rings extend to the tentacles and sense organs, and that the lat- 

 ter contained most peculiar nerve tissue. To understand that 

 and the endings of the different nerve fibers, requires detailed 

 histological study of sections of the various regions of the body. 

 This I hope will be done in the near future.
