length greater than that of the shaft. There are also very stout smooth sete, which 
serve for support and are rounded at the end. 
In the ventral setze there are found again two types of furcate seta. The first (Pl. 46. 
fig. 18) is comparatively strong, but not so massive as in L. complanata. The longer 
ramus is about four times as long as the shorter, has an incurved tip, and invariably 
bears a number of serrations on the internal margin. The serrate type is prevalent 
throughout. The second type is slenderer, and resembles the furcate setze of the dorsal 
bundle, but is rather more attenuate. The longer ramus often attains to as great a 
length as that described in the corresponding dorsal sets. This kind of bristle seems, 
after the middle, to pass partly into such a subfurcate seta as occurs in E. complanata, 
Locality. Mahlos Atoll, Maldives: a single specimen associated with several individuals
