Transverse section through the vagal lobe of Ameiurus nebulosus, illustrating a secondary gustatory neurone similar to that shown in Fig. 30. GoLGi method. X 60. As the figures show, they are very unlike the correspond- ing cells of the vagal lobe of the larger cyprinoid fishes, whose minute cell bodies are closely crowded around the periphery with the bushy dendrites thrust directly inward and giving off at the apex the neurite. These cells are exceedingly numerous in the carp and relatively few in the cat fish, and this fact doubt- less explains the difference in form. Probably neither type is very near the primitive form. Johnston figures in his Petro- myzon paper ('02, Figs. 7 and 21) chief cells of the vagal lobe of Lampetra whose cell bodies lie close to the ventricle and give off the neurite directly, while the busy dendrite is directed to- ward the periphery. Houser ('oi) unfortunately secured no impregnations of the chief gustatory cells of the shark, his prep-.
