The Journal of MoriUologv.—Vol. XX. No. .S. A STUDY OF THE LIFE-HISTORY AXD HABITS OF CH.ETOPTERUS VARIOPEDATUS, REXIER ET CLAPAREDE. HOWARD EDWIN ENDERS.With Three Plates. Introductiox. While I was at Beaufort, ^orth Carolina, during the season of1003, I became interested in the peculiar modifications that adaptChsetopterus to its sedentary mode of life. At the suggestion of Dr.E. A. Andrews I undertook to study its embryology and anatomy thefollowing season, but was unable to rear the larvse beyond the stageswhich E. B. Wilson has described. Toward the end of the seasonof 1905 I was successful in rearing lan^se from eggs to such a stagethat it was possible to know the younger larvse collected in the tow-ings. I was fortunate enough to find a sufiicient number of Chsetop-terus larvse in the towings to observe the important stages in the life-history and to rear the younger ones in the aquaria. In a brieftime they grew to stages that correspond with the young worms on thesand flats.
