Figure 11. Variation in keel width across the examined SBMNH lot. Scatter plot of keel width (KW) against shell length (ShL) for the single shell lot collected at El Mogote, La Paz, Baja California Sur, Mexico (24° 10' 00" N, 110° 24' 00" W) on 15 January 2000 (SBMNH 345766 & 345768). Eared shells (solid circles) and earless shells (open circles) distinguished. Linear regression lines for eared shells (dashed) and earless shells (dot dashed) with corresponding equations and coefficients of determination (i.e. R2 values) presented.
