St. 297. to the figure of Nakazawa, measures 1-3 mm., and unless the rate of growth is remark- ably great, it is necessary to suppose that there are many as five unknown stages, or eleven in all. I have accepted this number provisionally. The actual number of stages may seem a matter of small importance, but it must have some bearing upon the length of larval life and consequently on the possibilities of distribution. It is very disappoint- ing that in this, as in the other cases, the earliest stages are not represented in the material and speculation has to take the place 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 Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
