Figures followed by + indicate that the rattle strmg was broken but rattle increment is indicated by the use of the fine wire technique (see text). Figures in parentheses indicate increment not definitely known. Decreased lengths were recorded for snakes recaptured in some instances, probably due to error in measuring arising from variation in amount of stretching, in attempts to straighten them out and obtain relaxation. Some relax easily, and might measure long, while slight and hardly noticeable contractions in others may make them measure short. Smaller snakes could be measured much more easily and accurately than large and muscular ones, in which measurements were subject to a greater margin of 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 California.
