Distribution of the greatest diameter of the large light organ in the fifth row, expressed as percentages of the average diameter of the scale areas of the second row. A) C. sloani from the Atlantic. B) C. sloani from the Indo-Pacific. C) C. sloani secundus. Figure 3 shows the mean, range, ± two standard errors, and ± one standard deviation for the photophores of the fifth scale row. There is obviously no significant difference in the value of the mean for the three distributions. The distribution of C. s. sec- undus is quite symmetrical, while the two samples of C. sloani are skewed to the left. What significance, if any, this may have we are not able to 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.
