Much more generally distributed and constantly present are a few molluscs and crustaceans, such as are shown in Figure 20. There are a few adult insects (fig. 21) and many insects in immature stages (figs. 22, 23) and 24. Some help toward the recognition of these may be had from the table on pages 40 and 41, which contains brief hints, also, of the situation they occupy in the water and the role they play in the food consumption. There are leeches, and fresh-water sponges and bryozoans, and a host of lesser forms of many groups, mostly too small to.
