Excerpt from The Light Recipient Organ of the Copepod, Eucalanus Elongatus

Within the group of Copepoda the marine forms have been least studied, for the paper Of Richard which is the most thorough of any dealing with the more minute anatomy Of the nervous system, is concerned with only fresh-water forms. For twenty-eight years previous to the appearance of Richard's work there was none dealing primarily and specifically with the nervous system. Claus devoted a portion of his monograph on the non-parasitic Copepoda. To the anatomy Of the marine representatives, and in it we have the most complete, as well as the best, comparative study of the nervous system and sense organs of the pelagic forms that has appeared; The general disregard of the nervous system in the marine Cope poda would alone be reason enough for taking up the study at the present time. But in View of the closer attention which the nervous apparatus in decapods has received recently, a study of the lower forms for purposes of comparison seems especially desirable. The present investigation grew out Of a desire to gain some knowledge of the peripheral nervous system and sense organs of the Copepoda as a preliminary step toward a study of the reactions, including the diurnal and seasonal movements, Of these enormously abundant and very important plankton organisms. It is hoped that this paper may be one of several dealing with the nervous system, the central organs being taken up at a Subsequent time.
