oped. It is termed the axone cap and is primarily an acoustico- 
lateral connection. 
There is clear evidence that the different dendrites of Mauth- 
ner’s cell have different types of connections. The endings of 
the VIIIth root fibers upon the lateral dendrite in Ameiurus are 
well adapted for a study of the nature of the synapse. The two 
plasma membranes are seen in contact. The cell affords an ex- 
cellent material for the study of the structure of the cytoplasm.
