Text Appearing Before Image:
tentacles, the 4 radial onesbeing about as long as bell-diameter, the 4 interradial ones shorter. Tentacle bases havelateral spurs. Also about 24 small papillae on bell-margin, none having lateral cirri. 8lithocysts, each with 4 or 5 concretions. Peduncle slender and almost as long as the bell-diame-ter. Stomach cylindrical, two-thirds as long as bell-height. Mouth with 4 slightly foliated lips.The 4 large, swollen gonads occupy the middle two-thirds of the radial-canals on the peduncle. Bell nearly colorless. Tentacles and manubrium are of a bluish tinge and the gonadsare opaque, milky white. Maldive Islands, Indian Ocean; December. This species is most closely related to E. gentiana Haeckel, from the Canary Islands,but has smaller marginal cirri and a bell differing in shape. It differs from E. levuka ofFiji in the position of its gonads, for in E. levuka these are on the 4 radial-canals near thering-canal, while in E. lactea they are confined to the peduncle.
