Diagram of nephridium in longitudinal section. The actual distance between adjacent nephridia is commonly from mm. to mm. in the mounted sections, although some are sep- arated by only mm. or twice the diameter of the terminal bulb. All are placed in a very similar situation with regard to the blood lacunae and the nerve cords, always lying near the lumen of the blood space in the angle adjacent and somewhat dorsal to the nerve cord (Fig. 4). In many cases the terminal organ is situated on a low pa- pilla, formed of the endothelium of the blood lacuna and its underlying basement membrane. This papilla projects somewhat into the lumen of the blood space, so that the greater part of the surface of the ne- phridium comes in close proximity to the blood (Figs. 5, 6)..
