Figure 8. Comparison of the slow tail movement of A. roquet extreiniis (upper) with the rapid tail movement of A. trinitatis (lower). Numbers at the tip of the tail indicate frames elapsed from start of display (one frame equal to 1/16 second). A. Tail rise in extrcmus. The tail is slowly arched up. A full two seconds elapse before peak is reached. B. Tail lowering (same display). The tail is dropped more quickly than raised. Multiple dashes at 36 indicate tail was in rapid motion and film was blurred on that frame. Total time interval for sequence is 40 frames {IVi seconds). C. Tail rise in trinitatis. The peak is reached in 3 frames. D. Tail lowering (same display). The tail is down one frame later. Total time interval. 4 frames (Vi second). The drawings were made by superimposing images from a single frame Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
