One hundred ninety-four larvae of Symphurus plagiusa were taken in the lower Chesapeake Bay during a three-year zooplankton survey 1971-1974. Early larval stages (1.3-6.2 mm NL) are illustrated and described. Recently hatched larvae (1.3-2.8 mm NL) are distinguished by pigment patterns, gut configuration, and a fleshy occipital hump. Later larvae (2.8-6.2 mm NL) are identified by pigmentation, gut configuration and produced dorsal rays. Larvae were taken during July and/or August each year. Recently hatched larvae (1.3-2.9 mm NL) made up the majority of the catch and were most abundant in the deepest and most saline portions of the bay. Large estuaries may be more significant spawning areas for Symphurus plagiusa than previously reported. Evidence is presented that earlier descriptions of S. plagiusa larvae may be in error.
