GROW, DARSIE DARSIE We have not had any of these determined as yet. We should be glad to collectspecimens for anyone who would determine them for us. One or two kinds of tricladids are found uiuier stones. Most of these are bro\vnor gray, some are pink and some almost red. At least one species of polycladid is found cotnmonly under stones.
