A comparative study reveals the fact that this centre varies in size with the degree of differentiation of the lateral lines. Thus, in the sturgeon, whose other medullary centres are relatively feebly developed, this system is greatly enlarged and a portion of it has been differentiated in front to form the lobus lineas lateralis of Johnston (Text- figure 4, /. /.), the so-called

This acustico-lateral centre, like the vagal lobe, is difficult to correlate with anything found in the spinal cord. These cases, and many others which might be given, illustrate the way in which comparative anatomy assists.
