Steche showed the line as extending first of all almost at right-angles to the main axis of the float, and then as curling round in the oral direction. Thus he represented the last lateral group of cormidium III for example as approaching the chief tentacle of cormidium IV, whereas in fact I find that it lies next to the chief tentacle of cormidium II. The bud- ding line also does not run in the early part of its course as far down towards the lower part of the float as Steche showed it. Okada (1932) too has commented on this error of Steche's. Okada also correctly described the line of ' insertion' of the lateral groups as extending first obliquely downwards, and then upwards. These terms apply when looking down on to the animal as it floats on the water (Text-fig. 21). Steche's elaborate diagrams of a two-dimensional arrangement of the cormidia do not in my view
