All thoracic segments narrow, wider than long; first two abdominal segments longer, with setiger 8 about as long as wide; following abdominal segments narrow, wider than long. Thoracic noto- and neuropodia with simple fingerlike postsetal lamellae; abdominal notopodia also with simple postsetal lamellae; abdominal neuropodia expanded into inflated glandular lobe bearing weakly notched tip. Thoracic noto- and neurosetae all camerated capillaries; abdominal notosetae also camerated capillaries; abdominal neurosetae simple, smooth capillaries, some minute, hairlike. Branchiae not developed on this juvenile. Pygidium with two lobes surrounding anus; with two long, thin anal cirri.

These specimens were subsequently set up in Petri dishes in a refrigerator for later examination in life.
