Figure 5: Female from Pocasset River, Massachusetts, June 12, 1960. Figure 6: Female from Silver Glen Springs, Florida, Jan. 2, 1960. Figure 7: Female from upper reaches of Bass River, Massachusetts, Oct. 26, 1960. Figure 8: Male from Stony Brook, Massachusetts, Oct. 12, 1960. In addition to the number of parts, the arrangement of the parts tends to differ with the geographical origin of the animals. In the Pocasset River animals, the part of the pattern studied tends to be "squared off" at the base; the two large parts extend down to a hypothetical base line and the small parts on either side rest on this "base ; (See Figs. 3, 5, 7, 8.) If both arms are horizontal with the upper edges roughly parallel with this base line, the whole effect is one of rectangularity. The pattern of Lake George animals tends to be elongated rather than squared. As already noted, the arms reach upward, often with a widely flared V between the arm and the central vertical part (Fig. 6). Instead of the small pieces being arranged at the base beside the vertical part, the lower end of the vertical part may be truncated and the small pieces arranged as a downward but interrupted continua-.
