Papers . reserved materialthis pigment completely obscures the eyes, whUe in others the smaller pair only areinvisible. It seems probable that this condition is responsible for confusion in theclassification of this and related species, some of which have been described as havingonly one pair or no eyes. The peristomium is wider than the prostomium and usually is a little wider than thefirst setigerous somite. In some individuals there is a faint constriction, especiallynoticeable on the lateral and ventral areas, which obviously marks the boundarybetween the first and second somites. By a number of writers the possession of oneor two apodous somites has been regarded as of importance in the separation of this distinction really occurs it would be important as indicating that the secondapodous somite of one genus is homologous with the first setigerous of another. Inmy study of the LeodicidEe I have found so much variability between closely allied 164 Leodicidce fro7n Fiji and species of the same genus in the degree of distinctness of the first two somites that Ivery much doubt whether there is anywhere a Leodicid with only one apodous this assertion is perhaps going beyond the evidence in such a genus as Onuphis,it seems to me obvious that these lateral and ventral markings in Oenone indicateclearly a fusion of somites and that a classification which separates this genus fromothers because of the (apparently) single apodous condition is erroneous. The appearance of the ventral prostomial surface varies with the amount of pro-trusion of the palpal lobes, but it usually shows some longitudinal wrinklings. Inother respects there is nothing to be added to the descriptions already given by Fauveland others. The genera of the Lumbrinereinse with foliaceous dorsal cirri are somewhat confused,The first genera and species were described by Savigny (1820, pp. 55, 56, plate 5, and 3) as Aglaura fulgida and Oenone lucida.
