Although the primary gonad is normally bisexual and at least some degree of intersexuality is usually found in sexually mature yearlings, only 4 among 96 such individuals from W. Sayville and 4 among 389 from New Haven Harbor were classed as true hermaphro- dites. These showed approximately equal areas of male and female cells (Fig. 12, B). Several others were considered to be hermaphro- ditic males, being provided with spermaries of normal appearance except for the presence of scattered ovocytes (Fig. 12, A], sometimes fully grown. oc.
