Diagnosis Original diagnosis by Johnston (1865: 67): ''Lumbriciform, the body acephalous, distinctly annulated, flattish on the ventral aspect: first segment pointed: mouth inferior: segments crenulate, armed with setaceous bristles (No. I. fig. 5) in four fascicles; a segment (genital?) among those of the anterior portion of the body furnished with stout spines (No. I. fig. 4) in two fascicles: anus terminal, naked. Littoral.'' [details]
Etymology Not stated, uncertain. The Latin word valla is the inflection of the Latin noun vallum, and means 'wall' or 'rampart', but it is not clear to what it is referring to. [details]
