FIGURE 11. P1 elements of Wurmiella? polinclinata estonica and Wurmiella? polinclinata polinclinata. 1-11 are classified as W.? polinclinata polinclinata. 12 and 14 show some characteristics of each subspecies, but compare most closely to W.? polinclinata polinclinata. 13, 15-17 are classified as W.? polinclinata estonica.
