COMMENTS ON MATERIAL EXAMINED.—The types, from Ternate in the Moluccas, are not available. Fischli's description and illustrations are quite detailed; the following summary of his findings updates his terminology.

DESCRIPTION.—Medium-size specimen with 95 segments; length 14 mm. Ceratostyles with up to 30 moniliform articulations in A-III. A-III. to setiger 7. Peristomium cylindrical. Separation between peristomial rings distinct on all sides. Peristomial cirri to posterior edge of prostomium, with up to 7 articulations.

Maxillary formula 1+1, 5+5, 7+0, 5+7, and presumably 1+1. Mx III long, located behind left Mx II.

Branchiae present, pectinate, reduced in mid-body region, erect. Branchiae from setiger 6 to setiger 95. Branchiae present to near posterior end, present on more than 65% of total number of setigers. Maximum 5 filaments at about setiger 10. Mid-body setigers in 1 specimen with single filaments; posterior setiger with 2–3 filaments.

Ventral cirri basally strongly inflated in median setigers, less distinctly inflated in far posterior setigers. Inflated bases nearly spherical. Notopodial cirri with up to 5–7 articulations, most distinct anteriorly, but present in all setigers.

Limbate setae marginally smooth. Pectinate setae flaring, flat. Both marginal teeth distinctly longer than other teeth; ~15 teeth present. Appendages of compound falcigers tapering, tridentate. Distal tooth well developed. Guards symmetrically rounded; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae, presumably yellow or light-colored, distally gently double-curved, tapering to blunt tips; cross-sections round. Subacicular hooks tridentate with teeth in a crest. Starting segment for subacicular hooks not mentioned. Fangs decreasing evenly in size from large main fang to small tertiary fangs.

UNKNOWN MORPHOLOGICAL FEATURES.—Many features from all parts of the body.

EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEATURES.—None.

ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—None.
