Plots of Snout – Urostyle Length (SUL), TL/SUL, HW/SUL, GFW/SUL, GFH/SUL, and GFW/GFH. Plots are grouped according to species and sex where appropriate, and color-coded following Figures 1 and 5. Boxes represent the interquartiles. Whiskers extend to the most extreme data point no more than 1.5 times the interquartile range from the box. Width of each box reflects relative sample sizes (square-roots of the number of observations). Asterix mark the holotype measurement.
