Despite this simplifica- tion in structure the maxilla is relatively enormous compared with that of Nebalia, and this is due to the development of the first endite, which is approximately twice the length of the rest of the limb. It consists of a curved spoon-shaped plate armed on the inner edge with a row of closely set setae (Fig. 4 A). In Nebalia I pointed out (1927, p. 365) that the most anterior setae on this endite curve round the hinder face of the paragnaths just as do the setae of the proximal endite of the maxillule, and, since the limb projects at right angles to the body axis, the tips of these setae lie in one transverse plane. In Nebaliopsis the homologous setae occupy a similar position but, owing to the ant A.
